摘要

Abstract

Advances in organic photovoltaic technologies have been geared toward industrial high-throughput printing manufacturing

which requires insensitivity of photovoltaic performance regarding to the light-harvesting layer thickness. However

the thickness of light-harvesting layer for all polymer solar cells (all-PSCs) is often limited to about 100 nm due to the dramatically decreased fill factor upon increasing film thickness

which hampers the light harvesting capability to increase the power conversion efficiency

and is unfavorable for fabricating large-area devices. Here we demonstrate that by tuning the bulk heterojunction morphology using a non-halogenated solvent

cyclopentyl methyl ether

in the presence of a green solvent additive of dibenzyl ether

the power conversion efficiency of all-PSCs with photoactive layer thicknesses of over 500 nm reached an impressively high value of 9%. The generic applicability of this green solvent additive to boost the power conversion efficiency of thick-film devices is also validated in various bulk heterojunction active layer systems

thus representing a promising approach for the fabrication of all-PSCs toward industrial production

as well as further commercialization.
