Polaris solar PV net news: according to a report published recently by the global renewable energy development to 2014, according to the 2013 global PV market, its capacity up to 38.7GW, which were added to 12GW, rose 232%, close to 2013, its capacity in Europe put together. From the global PV market with a European core region is gradually moving towards Asia, and China surpassed the old PV powerhouse Germany as the world’s largest PV markets.
Meanwhile, the report shows that 2013 global thin film solar cell production capacity reached 8.4GW, about 4GW, capacity, production is more 20%-2012 film power development was steady development trend in the world. Film generating more attention, with no pollution, low energy and a wide range of applications and the technical advantages of low costs per kilowatt are inextricably linked. From a development point of view, some time in the future, film power there is still much room for improvement and potential.
In recent years, the PV industry achieve sustained development of China is closely linked with the rise of films generating industry and technological breakthroughs. In terms of film technology, Copper-Indium-Gallium-selenium (CIGS) technology is developing most rapidly and is widely used, 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.” In this sector, represented by Hina, thin-film CIGS production components of the power plant already has high photoelectric conversion rate has reached 15.7%, and is gradually increasing speed of about 1% per year, estimated 2020 production module efficiency of up to 20% per cent.
Due to the Copper-Indium-Gallium-selenium thin-film solar cells without light-induced decay, radiation resistance, stability and high conversion efficiency is very high and can be made of flexible components, such as unique advantages, Copper-Indium-Gallium-selenium thin-film technology has a very strong market competitiveness, and building integrated photovoltaics (BIPV), flexible roofs, residential areas such as power generation, automobiles are expected to be large-scale application.
Thin film solar power generation technology in building integrated photovoltaic (BIPV) has huge market potential. In broad terms, building integrated photovoltaic (BIPV) is to make thin-film solar power generation panels combined with roof and wall surfaces of buildings, turning each building small power plants, electric power “spontaneous use, redundant Internet access” without covering or long distance transmission. In the industrial field, today most industrial plants using cannot be load-bearing lightweight steel roof, traditional rigid photovoltaic modules cannot be in a typical industrial plant because of the larger mass promotion. In industrial roofing applications, flexible thin-film components using flexible substrates can be bent, you can paste the installation, more promising in the construction market: on the one hand, flexible thin film solar module lighter for the same area may meet the requirement of non-load-bearing weight on the roof, on the advantages that can be bent, you can paste the installation can meet the design and aesthetic requirements.
According to the National Bureau of statistics data, the calculation that by 2020, China’s urban and rural housing construction area is about 89 billion square meters, East, South and West walls area of area of 15% rooftop 10%, direct market size of more than 10 trillion yuan, indirect market size of 30 trillion yuan, equivalent to China’s auto market 3-5 times. Even under the 10% conversions and solar 1300 power hours per year on average, capacity equivalent to 368 gezhouba or 45 Three Gorges, alternatives to 30% per cent of the annual electricity consumption of the whole society needs could reduce carbon dioxide emissions by about 1.3 billion tonnes per year, approximately equivalent to the annual emissions of 20% in our country.
