in the new generation of high-efficiency solar cells, HJT technology lead a new round in PV technology. With a single hybrid structure integrating the advantages of crystaline siicon and amorphous sicon thin film technology. HJT solar cell has the advantages of high eficiency and stablity with a low-temperature and simplified manufacturing procedures. Extremely low temperature coeficient so as to avoid lD and PlD effect, There is no color diference between the front and back side, the bifaciality is more than 95%. The backside has an obvious advantage in power generation, which ensures a stable and high eficiencypower output reaardlessof seasonal circulation and climate change.
