Abstract

Abstract : A well‐organized donor –acceptor crystalline structure is examined for high ­performance nonfullerene solar cells. By thermal annealing, nanoscale structures of both donor and acceptor domains are successfully modulated, followed by ­significant changes in the resulting ­photovoltaic characteristics. When annealed at 90 °C, a maximum power conversion efficiency of 7.64% with a ­remarkable open‐circuit voltage of 1.03 V is obtained.
