Abstract:Dopant‐free hole transport layers (HTLs) are crucial in enhancing perovskite solar cells (pero‐SCs). Nevertheless, conventional processing of these HTL materials involves using toxic solvents, which gives rise to substantial environmental concerns and renders them unsuitable for large‐scale industrial production. Consequently, there is a pressing need to develop dopant‐free HTL materials processed using green solvents to facilitate the production of high‐performance pero‐SCs. Recently, several strategies have … Show more
The designed copolymer PATTBTT delivered a power conversion efficiency of 17.6% in PSCs, which was higher than those obtained for reference devices fabricated using conventional polytriarylamine-based hole-transport materials.
