According to the Russian "STRF" science website on March 25, the research group of the Institute of Physics and Technology of the Russian Academy of Sciences to develop a new solar thin film battery, this silicon-based solar cell module, the photoelectric conversion efficiency theory Up to 27%.
Russia's "Хевел" company, through its cooperation with Switzerland, produces solar cells at the Russian plant to produce thin film solar modules with an annual output of 100 megawatts. Production technology in Switzerland ensures that the solar cell modules produced have a photoelectric conversion efficiency of 8.9%. In order to improve the technology and further improve the photoelectric conversion rate, in 2010, Russia "Хевел" company established a thin film solar cell technology research center at JOMEX Institute of Physical Technology. The researchers of this center gradually changed the photoelectric conversion of the thin film solar cell Efficiency is increased to 10% and further to 12%.
In a parallel study, Russian researchers are working to perfect a new product based on thin-film silicon solar cells. In 2012, Japan's Sanyo solar cell patent based on crystalline amorphous heterojunction technology expires, the Russian scientists with the patented technology, the use of the Russian Nobel Prize winner Alferov on photoelectric heterogeneity research results, research and development A new solar thin film battery. The new solar thin film battery based on silicon materials, the production of the use of plasma chemical deposition method to form a layer of amorphous silicon nanocrystalline thin film on the surface of the crystalline silicon. At present, the photoelectric conversion rate of industrial samples produced by the research center based on the thin film solar module of this technology has reached 21%, which is nearly twice that of the traditional thin film solar module.
