Robust performance of PTQ10:DTY6 in halogen-free photovoltaics across deposition techniques and configurations for industrial scale-up
简介:With performance improvements,organic photovoltaics(OPVs)are an increasingly competitive technology for renew-able energy.However,most high-performance OPVs are small-area devices processed from toxic halogenated solvents via spin-coating,posing a challenge for mass production.We study a low-cost polymer donor(PTQ10)and a non-fullerene acceptor(DTY6)in a halogen-free solvent using industrially relevant blade coating.The non-inverted architec-ture performed best,achieving 12ficiency,with the blade-coating deposition surpassing spin-coating.Active layers processed from the two coating techniques exhibited similar exciton quenching,likely due to the same measured nan-odomain size and purity.However,blade-coated devices exhibited a higher charge carrier lifetime correlated with in-creased acceptor pi-stacking despite decreased donor pi-stacking.This suggests that optimizing crystallinity in blade-coated devices could result in even higher performance.Additionally,high performance in upscaled blade-coated de-vices(1 cm2)processed in air with a green solvent demonstrated the industrial potential of this system.展开
