News May 1, 8% conversion efficiency for the international advanced level;-per-watt of crystalline silicon using crystalline silicon cells is equivalent to the volume of 1% of the cost of production greatly reduced.
This reporter recently from China, ENN Solar Energy Co., Ltd. Was informed that a piece of China's first super-large 5.7 ㎡ Binodal line silicon thin film solar cells will be May 6 at the opening of "SNEC Third (2009) International Solar Light V General Assembly "formally unveiled.
According to ENN Solar Dr. Wan Kejia general manager, ENN Solar's large dual-end silicon thin film solar cells have achieved conversion efficiency of 8%, silicon-based thin-film battery is the international advanced level; at the same time, product-per-watt of crystalline silicon used in the volume of crystalline silicon cells is equivalent to only 1%, significantly lower cost-per-watt battery, to avoid the production of crystalline silicon in the process of high energy consumption, more conducive to energy saving and environmental protection, applicable to vehicle battery charging station, residential roofing, building walls and large-scale power plants and other fields, has a broad application space.
It is, ENN Solar Energy Co., Ltd.'s Super silicon-based thin film solar cells into mass production soon. This super-size solar cells, PV modules can greatly reduce the installation costs, and lower system cost of power generation, especially for large power station.

China's first large block of solar cells available
Self-cleaning, low-reflectivity surface to improve the efficiency of 2% of the battery
United States Georgia Institute of Technology are developing a technology, it is highly likely to c-Si solar cell conversion efficiency by as much as 2 percent.
Fellow of the Institute adopted the two different types of chemical etching method to produce micro-and nano-scale surface features, an increase of light absorption rate, a decrease of reflection, so that the battery maintain a clean surface.
Through the three-dimensional structure to capture sunlight, and the production from a clean surface - to allow the accumulation of rain or dew in the battery array wash away dust and dirt, the surface treatment to increase the light absorption rate. As a result of free water in the above and scroll down, the surface characteristics have been defined as a super-hydrophobic. "More sunlight to enter the photovoltaic cells, and little is reflected back to reach higher efficiency," Georgia Institute of Technology Materials Science and Engineering Professor CP Wong said, "The simulation results show that this surface We have the ability to structure the final battery efficiency by 2%. "
Wide Fund for Nature in the United States and Georgia Institute of Technology National Electric Power Test Research and Application Center, with the support of the study report was completed in March 24 in Salt Lake City in spring 2009 at the American Chemical Society national meeting.

SRI: 2013 global solar market will reach 70 billion U.S. dollars
April 28 news according to SRI Consulting's latest report, the global solar market will double in 2013, reaching 70 billion U.S. dollars. Due to the volatility of oil prices in recent years and the effects of global warming, renewable energy development has been increasingly widespread support, the company explained. The first and second generation of photovoltaic cells require different forms of silicon, very little of the transition metal elements, as well as non-metallic elements. Thereby increasing the price of silicon material. The third and fourth generation of technology to focus on organic polymer and nano-materials, thereby reducing production costs.
"Organic photovoltaic cells research in recent years has made tremendous progress. The conversion efficiency has been more than 5%. Of course, commercial silicon cells are still the main market, because its conversion efficiency has exceeded 25%."
SRIC's report examined the photovoltaic industry in new equipment. From raw materials to final production, the field of solar energy has a very great opportunity, and is increasing at an alarming pace. Organic battery manufacturers are now actively seeking cooperation with the electronics companies.
