According to news from Xinhua News, Aug. 29, Japan, improving the conversion efficiency of solar cells has always been a major problem for the global industry. In general, it takes a year for each 0.1% increase in solar cell conversion efficiency. Recently, the research groups of Kyoto University and Tohoku University in Japan have developed a new technology that can increase the photoelectric conversion efficiency of solar cells by 2%, without increasing production costs, and accelerating the development of the solar energy industry.
According to the "Nihon Keizai Shimbun" news, research groups at Kyoto University and Tohoku University have developed a manufacturing technology that can increase the efficiency of solar cell power generation. After the technology is applied to residential silicon-type crystalline solar cells, the photoelectric conversion efficiency of the battery can be increased to 18%, and the manufacturing cost will not be higher than that of existing solar cells. At present, the research team is working with companies and plans to produce batteries using this technology within 1 to 2 years and sell them to the market.
Polycrystalline silicon batteries are relatively simple to manufacture because they are crystallized. They are always cheap and are the main solar cells used in residential buildings. Currently, the photoelectric conversion efficiency of solar cells sold on the market is generally around 16%, and it takes about 1 year for each 0.1% increase. In order to compete for markets, companies in various countries are actively developing new technologies that increase the photoelectric conversion rate.
Kyoto University professor Junichi Shigetsu made full use of silicon crystals to develop technologies to increase power generation efficiency. This technology does not require changes to the production process and does not increase production costs. At present, the research team is cooperating with the “First Electromechanical†company that manufactures crystallization devices and tries to produce batteries using this technology. The research team revealed that the new technology may increase the photoelectric conversion efficiency of the battery to about 20%. (Reporter Wang Peng reports)
