摘要：

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. Copyright © 2016 Wiley-VCH Verlag GmbH & Co. KGaA.
