Molecular Engineering Pushes PTAA Perovskite Solar Cell Efficiency Past 26 Percent

Tokyo, Japan (SPX) Apr 23, 2026

Researchers from Dalian University of Technology, Fudan University, and City University of Hong Kong have developed a molecular design strategy that pushes PTAA-based perovskite solar cells (PSCs) beyond 26% efficiency. Led by Professor Ze Yu, Professor Yingguo Yang, and Professor Hin-Lap Yip, the team addressed a persistent bottleneck in 2D/3D heterojunction devices: poor carrier transport caus
