Russian scientists have developed solar thin film batteries
According to the Russian "STRF" science website on March 25th, the research team of the Institute of Physics and Technology of the Russian Academy of Sciences has developed a new solar thin film battery, the solar cell module based on silicon material, its photoelectric conversion efficiency theory can be Up to 27%.
Russia's "Хевел" company cooperates with Switzerland to set up a solar cell in Russia, with an annual output of 100 megawatts of thin-film solar modules. The production efficiency of the solar modules produced by the Swiss production technology guarantees a photoelectric conversion efficiency of 8.9%. In order to improve the technology and further improve the photoelectric conversion rate, in 2010, Russia's "Хевел" company established a thin film solar cell technology research center at the Institute of Physical Technology, and the researchers of the center gradually converted the photoelectric conversion of the thin film solar cell. The efficiency is increased to 10% and thus to 12%.
In parallel research, Russian researchers are working to perfect a new product, a thin-film solar cell based on silicon. In 2012, Japan’s Sanyo’s patent for solar cells based on crystal amorphous heterojunction technology expired. Russian scientists used the patented technology to develop research results on the heterogeneity of photoelectricity by the Nobel Prize winner Alferov. A new solar thin film battery. This new solar thin film battery is based on silicon material, and a nano-film of amorphous silicon is formed on the surface of crystalline silicon by plasma chemical deposition. At present, the industrial sample photoelectric conversion rate of the thin film solar cell module based on the technology produced by the research center has reached 21%, which is nearly twice that of the conventional thin film solar cell module.
