The scientific team from the Institute of New Energy Technology of Jinan University has made a breakthrough in the research of large-area polymer substrate flexible perovskite photovoltaic modules, bringing the efficiency based on trans structure to 20.20% (12.11 cm2) and the aperture area efficiency to 19.21% (12.74 cm2), which are the highest conversion efficiency records so far. The samples showed excellent stability in the maximum power point tracking test.
The research was jointly conducted by Professor Mai Yaohua, associate researcher Liu Chong and Wu Shaohang and doctoral student Zhang Cuiling. The achievements have been tested and certified by the National PV Industry Measurement and Testing Center.
