CIGS “lost years”: the way back

Polaris solar PV net news: with the withdrawal of the Bosch Group and the place des Vosges, clamor about “PV lesson on” resurgence. After after several years of struggling, Vosges stake finally gently down the CIGS project, contributed to more than 50 million RMB seeking transfer. Former ally–early in the Bosch Group has decided to withdraw from the photovoltaic manufacturing business, not just the CIGS, Bosch has stopped in early 2014, including silicon ingots, wafers, solar cells and related components for all production of photovoltaic products, formally withdrew from the once-booming industry.

As held to “teach” people typically, prestige value because of the photovoltaic industry has been up and down a couple of percentage points. However, PV abused me many times, I treated PV as first love, CIGS thin-film industry is also true. As the stock market, it was left to sell, nature was also bullish on “buy”. The latest news is that Fujian’s first CIGS thin-film photovoltaic technology Jingfu intercontinental energy technology company in Nanping city of jianou officially inaugurated. This is the fourth announced since 2014 CIGS thin-film technology projects, and Hina’s multi-billion dollar investment plan, € 300 million in Jiangsu baoying CIGS project base, changshan was worth 1.8 billion in joint energy projects … … 2014 total over billions of CIGS thin-film manufacturing operations, seemed to let people return to the 2011 years ago during the peak of PV industry.

Recalling China PV industry this decade in a hurry, one of the most obvious problem is the excessive concentration of investment, and caused severe overcapacity. Only a solar cell capacity in China will be able to completely cover the global installed capacity requirements, direct consequences of overcapacity is a loss sustained losses. More and more business is unsustainable and had to give up the light industry, place des Vosges and Bosch’s frustration lies. 2014 CIGS thin film investment boom will not to repeat it? This is of course a big fear of police, but the CIGS thin-film investment directly gives people another think: CIGS thin film is probably the case. 2014 investment return, just let our PV industry walked a road originally led–CIGS, polycrystalline silicon and thin-film complement each other, “not abandon”.

Crystalline silicon, thin film: who is the mainstream is not important

Recently, a Chinese first-tier hydropower development staff by GCL Chairman, Mr Zhu’s open letter in the solar circle go crazy. This occasion was held in Beijing on September 11, “2014 solar leaders Summit”, the GCL and Yingli group, two executives support c-SI, directed at the film route weaknesses. Thin-film crystalline silicon PV and PV road battle seems to be opened again. Mr Gao is Trina said that some alternative to crystalline silicon film companies say the future is nonsense, crystalline silicon the mainstream 5-10 will not change in the future, thin-film batteries only when the supporting cast.

Farce that has begun. Yes, since 2009, thin film solar module production reached 19% after the highest proportion of global production, and thin-film solar market has been significantly related to the recession. Reasons are pretty simple, except for some very few examples in addition to thin film solar module prices are relatively expensive, inefficient, than Chinese now dominate the mainstream market compared to crystalline silicon solar cell technology profitable.

However, as repeatedly on related enterprises in the key technology breakthroughs, CIGS thin film is no longer drops. Data from OFweek industry research center showed that 2013 global thin film solar cell production capacity reached 8.4GW, about 4GW, capacity, production is more 20%-2012. In terms of efficiency, in September this year, Manz group in Baden-Fu Dengbao CIGS thin-film solar technology research and development partner State Centre for solar energy and hydrogen research (ZSW), CIGS thin film solar efficiency hit a new world record of 21.7%. It is thin-film solar technology never before seen in the highest conversion efficiency, significantly beyond the current polysilicon solar technology to mainstream records.

CIGS thin-film technology has broken the amorphous silicon solar cell efficiency in “monopoly”. Even say, step by step, with the technical potential of CIGS were discovered, once plagued with thin-film photovoltaic cost problem has been greatly eased, which we mentioned in the post.

As the GCL You Da had considered, comparing polycrystalline and single crystal who is leading meaningless, crystalline silicon and thin film is a meaningless thing, these are just two different directions. “Crystalline silicon and thin film are complementary, who is out and who is not an issue. “In response to Mr Zhu reply letter says so.

CIGS thin-film: an original road

Solves the problem of who are mainstream, we step back to look at CIGS’s status: why CIGS is a road originally?

As we all know, SI route always occupies a leading position in the global photovoltaic industry. Before 2009, the global polysilicon prices soared to a historic peak, and amorphous silicon solar cell costs rising, makes thin-film solar wind is good. Thin-film solar cell industry gained rapid development during this period.

However, Chinese domestic CIGS industry started in the late period. Before 2001 the domestic units rarely engage in CIGS thin-film solar cells research, and countries with low budgets, battery technology is difficult until the “ten five” period Copper Indium selenium, solar cells are included in the national 863 key issues, which have made considerable progress in China. And then got out of hand, the emergence of a large number of areas such as Hina, place des Vosges, Putney best CIGS companies such as solar energy, and CIGS also once known as the “King of film.” It can be said that these are normal “growth”, the CIGS PV industry in China will become another following amorphous silicon solar cell.

But why such good opportunities, CIGS thin-film technology in China is still in such an awkward position? I think the main reason is the Chinese PV companies are too fancy to benefit in the short term due to utilitarian. So-called utility is reflected in the following aspects, blindly hypnotized by amorphous silicon solar cell burst of prosperity, concentrated investment in the photovoltaic industry a lead in a film, amorphous silicon bipolar PV industry structure unbalance; be deterred by CIGS technology development cycles, money lost in terms of technology development initiative. Even though a few companies recognize the great potential for CIGS thin-film technology, amorphous silicon solar cell under the monopoly situation, it’s hard to set off waves.

A direct consequence of this is that serious excess capacity of crystalline silicon PV industry. Along with the United States, the European Union and other major solar markets have on China’s limits on crystalline silicon solar products, China PV industry never recovered. Temporarily scenery no two of PV giant Wuxi Suntech crashing collapsed, cold of PV winter in the, whole China crystal silicon PV industry are in “double anti-” of prestige Xia howling shaking, price, and losses, global PV enterprise are because serious of price chaos was, component Enterprise basic unprofitable, Vosges and Bosch of exit, except operating strategy of problem, is big part is on this deteriorated of big environment of compromise. PV cold winter that two years is not only the end of crystalline silicon PV, as represented by the CIGS thin-film PV has also lost several years of development opportunities.

Transition is around the corner it’s time to pick up CIGS

The beginning of 2013, China began to shift from foreign to domestic PV Market Center. With the strong support of the Chinese Government, conservative domestic solar market and finally was knocked by 1.1 points. According to OFweek Research Center data show that in 2013, China’s new PV 11.3GW, is the photovoltaic industry since the birth of the highest value. It is estimated that 2014 PV installed capacity can be maintained at a level about 10GW. Large font size, energy companies and the strength of private companies are struggling to carve up this big cake.

Energy giants have entered, indeed to the crumbling of PV industry in China has brought boundless vitality. But unfortunately is that the layout of most enterprises are still stuck in the silicon industry chain category. Prospects for a more representative of the industry’s film industry investment, even if it concerns energy “national team” very few businesses.

Breakdown for thin film type of power generation technology, nowadays the CIGS technology is developing most rapidly and widely, has become a major film generation technology trends, is now recognized as one of the most promising generation of thin film technology was widely rated as “the future of solar energy.” This which of key causes is, CIGS film solar no light to attenuation phenomenon, and anti-radiation performance high, and stability and conversion efficiency quite excellent and can made flexible component, unique of advantage, Copper Indium Gallium se film power technology has very strong of market competitiveness, and in PV building integration (BIPV), and flexible roof, and households with power, and car, field can get scale application, can be described as future light.

Short story: “the lost years” in the CIGS defenders

Rush for 40 years

In 1975, the electron physics Research Institute at the University of Stuttgart has opened the CIGS technology lab studies, 1987, Manz group was officially established. Nearly 40 years of accumulated scientific research makes the Manz group retains history in CIGS fields and deep solid technology base.

Today, the Manz group has grown to become the world’s only equipment supplier with CIGS module volume production experience. Manz CIGS turnkey production line adopts a linear co-evaporation source, unique to the world of high-end technology, under a certain amount of capacity, through the core technology of the production of CIGS Manz component yield is over 94%, efficiency increase over 15.3%. More critical is the use of local materials, can dramatically reduce material costs and factory construction costs.

The latest news is that in September, the Manz group in Baden-Fu Dengbao CIGS thin-film solar technology research and development partner State Centre for solar energy and hydrogen research (ZSW), CIGS thin film solar efficiency hit a new world record of 21.7%. It is thin-film solar technology never before seen in the highest conversion efficiency, significantly beyond the current polysilicon solar technology to mainstream records.

Thin-film photovoltaic people South of cloud

The Yunnan stone forest, the first reaction of most people hear the word: this is a famous scenic spot. In fact, it is only an interpretation of it, in a simple search on the Web, in addition to “the stone forest scenic spot in Yunnan province,” outside of the senses, “Shilin Yi Autonomous County, Yunnan province,” also crops up. People familiar with the domestic photovoltaic industry will know is located in Shilin, Yunnan, the largest 1-MW grid-connected solar power plant July 2012 completion of the mulberry trees, blue sky in Beijing automation technology co.

Say it focuses eyes of the PV industry, because the thin film solar power plant using CIGS technology, is China’s first demonstration in the CIGS thin-film solar project, described as a commercial use of the CIGS thin film solar cell breakthrough. And, according to plant operators monitor data, run the product performed well so far, although the most critical parameter is the product in terms of cost and conversion than solar cells of polycrystalline silicon slices, but due to the low light intensity, wider absorption spectrum, as well as better power performance at higher temperatures, power generating efficiency higher than comparable crystalline silicon solar power station is about 10%.

Shanghai CIGS the first person: and all our stakeholders “game”

Graduated from Cambridge in 2005 to return, NI Huan in the United Nations Development Programme and the World Bank Group and other institutions engaged in the study of low-carbon industries. During the Spring Festival this year, in located on the first floor of her home garden installation of photovoltaic power stations. From March onwards she investigates some household PV power station project, first developed crystalline silicon solar panel design because neighbors blocked.

Cambridge alumni in May at a party, she met were engaged in Copper-Indium-Gallium-selenium (CIGS) thin-film solar cell business students, the two men hit it off, and redesigned the use of Copper-Indium-Gallium-selenium thin film solar cell power generation programme, also makes her the first domestic installation of Copper-Indium-Gallium-selenium thin-film solar cells for home users. On April 20 to the power company for the record, May change the power plant programme, July 22 film power station completed, August 3 power generation. Talking about this experience the greatest experience, NI Huan feeling is, to all stakeholders “game.” But NI Huan said, “I’m enjoying the process, although not so well, but I still find it interesting. “In fact, in the mid to late August, NI Huan until 6 o’clock in the afternoon there is a power output of photovoltaic power station, crystalline silicon will not have such effects. At the same time enjoy the installation process, NI Huan also in the enjoyment of your choice.
