In the future, while the industrial chain is further improved, China's photovoltaic will also develop in the direction of technological innovation. With the change of technology, the conversion efficiency of solar cells has been continuously improved, and the conversion efficiency of general commercial solar cells is about 10% to 24%. At present, the highest record of solar cell conversion efficiency in China is created by the silicon heterojunction cell independently developed by Longi Green Energy, up to 26.81%.
