"In half a year, the efficiency of perovskite laminated battery has increased by 1%, which is unparalleled by other technologies. The efficiency of crystalline silicon battery has only increased by 0.1% in the past five years." Shen Chengyong, co-founder and CEO of Renshuo Photoenergy, told Shanghai Securities News that the efficiency of Renshuo Photoenergy's laminated battery laboratory is expected to exceed 30% next year.
Tan Hairen, chairman of Renshuo Photoenergy and professor of Nanjing University, told the Shanghai Securities News that the breakthrough in conversion efficiency showed that the efficiency achieved by the technical path of perovskite laminated perovskite (i.e. all-perovskite laminated battery) was far higher than that of single-junction perovskite battery. "We have always predicted this, but now we have proved it from the experimental results." He said that the laboratory efficiency of single-junction perovskite battery has not improved in the past year or two, and remains at about 25.7%. In contrast, the efficiency of the all-perovskite stack battery has broken through faster, and it is far from reaching the upper limit.
