SolarBlade1/2 cell cutting system: the inevitable path of high efficiency solar cells

Technical unit: ASM renewable

Last year January 8, NDRC, eight Department door released of energy efficiency “lead who” system implementation programme, which clear proposed: silicon PV battery pieces conversion efficiency reached 17% above, polysilicon PV battery pieces conversion efficiency reached 16.5% above; February 6, National Energy Council again issued on play market role promote PV technology progress and industry upgrade of views (sought views draft) pointed out that, will strictly implementation PV products market access standard. Starting in 2015, enjoy State-subsidized solar power projects use photovoltaic components and grid-connected inverter products should meet the standard conditions of the PV manufacturing industry-related requirements. Among them, the polycrystalline silicon solar module conversion efficiency of not less than 15.5%, monocrystalline solar module conversion efficiency of not less than 16%, multi and monocrystalline silicon cell conversion efficiency of not less than 17% and 18.5%, respectively.

Signs show that the national authorities are sparing no effort to promote the efficient application of photovoltaic products and set stricter market access standards, promoting industry survival of the fittest.

Global PV market development depends on the degree of cost reduction, photovoltaic conversion efficiency is a core element of cost reduction. Standard daylight conditions, the surface solar radiation energy density up to 1000W/m2, PV modules can be collected about 157-175W/m2 of energy, PV can be sampled only 125-140W/m2 to the energies. Development should focus on reducing the cost per kilowatt of solar photovoltaic technology–the key lies in conversion efficiency.

ASM renewable Zhiming Chen, Senior Sales Manager, the so-called high performance battery, basically involves “halves” technique, although ASM advocates 156mmx156mm slicing SolarBlade 1½ cell cutting system at home and there is no universal, however, ASM has seen the China from the Government to a power plant investment level of consistency: effective capacity is the core of China’s future power plant application.

Zhiming Chen said currently SolarBlade 1½ cell cutting system, for its essence for solar cell conversion efficiency, greatly increased slicing yield in the process, and in foreign countries take the lead in planning applications. Now ASM has received more than 500MW SolarBlade ½ orders for cell cutting system. By Zhiming Chen’s estimate, the next few years, with the power plant investment in China as well as increasing pressure on component manufacturers to parity, increasingly high demands for cost per kilowatt. “Half of” large scale application technology will be in the country. At the same time ASM synchronization technology of high efficiency solar cell cost reduction efforts. Such as steel plate printing technology research and development. Its advantages based on three points: 1. fine grating lines become narrower, less paste for even 2. increase conversion efficiency, 3. longer service life of the steel plate.

Technical units: the Dow Chemical Company

In the actual operation of power plant, generation——-most key components is decaying. A power plant operation and maintenance engineers in the industry, put into operation since 2011-SI based PV power plant, generally facing degradation, capacity reduction problems. Germany Fraunhofer ISE 2012 on world range within of component fault situation also for has statistics, which common of component quality problem has debris (hidden crack), and welding connection sex failure, and battery tablets attenuation, and wiring box material and line cable insulation failure, and hot spot, and package material (EVA) of off layer, and potential induced attenuation effect (PID), and interconnected failure (welding), and back Board of mechanical performance failure, and received plug-in fault,. In recent years, as the technology advances, some of these problems have been rare, and there are always new problems emerged. Component power attenuation in the Northwest has been appearing in a wide range of on-grid PV power station. In response to the component power losses, some power plant investors have begun for component suppliers in the purchasing contracts of PV modules is clear power indicators. This also means that the current PV module power attenuation has been upgraded to a more central level.

At present, the world’s largest chemical company, Dow Chemical Company to the domestic photovoltaic modules photovoltaic module sealants are recommended customers ENGAGE POE film raw material.

Dow Chemical argued because POE the raw materials used, the company found that, compared with EVA film, POE, such as packaging film made from ENGAGE power performance is better, less water vapor transmission rate, weather and better performance. While the core is made of POE encapsulated membrane can greatly reduce the attenuation effect induced by electric potential (PID), very suitable for n-type batteries and double glazing module. Select ENGAGE POE that encapsulates the purpose of membrane materials, Dow elastomers sector global strategic marketing manager Michael Shoemaker said stems from their customers in China use the feedback, this is confirmed, the current domestic power problem PV PV industry is causing concern.

Michael Shoemaker, says Mr PV Application market is developing very fast in China, in order to cope with the structural changes in the market, Dow relies on Saudi Arabia and Thailand two manufacturing centers, establishment of a research and Development Center in Shanghai, China, to prepare for the fast-growing solar PV market in this region.
