The quaternary strategy allows adding two extra components into host systems to tune the charge transfer dynamics and charge transport mechanisms of the active layers. Hence, it is an attractive approach in organic photovoltaic cells (OPVs). This study presents a new case that supplies a record efficiency of 17.1% by using PCBM and a fused-ring based nonfullerene acceptor as the guests. It presents detailed study on influences of proportions of the three acceptor components on the active layer structure, hole transfer dynamics and solar cell performances. The impressive efficiency is achieved by effective tuning on the shortcircuit current-density, which is due to the modulation on charge mobilities and accelerated hole transfer, in relation to the subtle difference of the active layer structure via tuning the proportions of the acceptor components. Therefore, this study again demonstrates the value of the quaternary approach in the OPV field (See the article by Kun Li, Yishi Wu, Xuemei Li, Hongbing Fu & Chuanlang Zhan on pages 490‒496).
