Highly π-extended copolymer as additive-free hole- transport material for perovskite solar cells
Organolead halide perovskite solar ceils have achieved a certified power- conversion efficiency （PCE） of 22.1% and are thus among the most promising candidates for next-generation photovoltaic devices. To date, most high-efficiency perovskite solar cells have employed arylamine-based hole-transport...

| description | Organolead halide perovskite solar ceils have achieved a certified power- conversion efficiency （PCE） of 22.1% and are thus among the most promising candidates for next-generation photovoltaic devices. To date, most high-efficiency perovskite solar cells have employed arylamine-based hole-transport materials （HTMs）, which are expensive and have a low mobility. The complicated doping procedures and the potentially stability-adverse dopants used in these HTMs are among the major bottlenecks for the commercialization of perovskite solar cells （PSCs）. Herein, we present a polythiophene-based copolymer （PDVT-10） with a hole mobility up to 8.2 cm2-V-l.s-1 and a highest occupied molecular orbital level of -5.28 eV as a hole-transport layer （HTL） for a PSC. A device based on this new HTM exhibited a high PCE of 13.4% under 100 mW-cm-2 illumination, which is one of the highest PCEs reported for the dopant-free polymer-based HTLs. Moreover, PDVT-10 exhibited good solution processability, decent air stability, and thermal stability, making it a promising candidate as an HTM for PSCs. |
