Abstract

Embedding a third and/or fourth component into a binary blend active layer of organic photovoltaics (OPVs) is a promising approach to achieve high-performance photovoltaic cells and modules. This multicomponent strategy favors absorption broadening via additional components. Quaternary OPV (QOPV) blends have four components in three possible configurations: (i) a donor and three acceptors, (ii) two donors and two acceptors, or (iii) three donors and an acceptor. Although quaternary systems have only been relatively recently studied compared to other systems in OPVs, leveraging the synergistic effects of the four components leads to record power conversion efficiencies, currently approaching 20%. QOPVs provide ample material choices for compatibility and channels for charge transfer mechanisms, possibly leading to optimized morphology and orientation. Reviewing recent progress in advancing QOPVs is essential for understanding their contribution to the OPV field. The review mainly discusses research progress in QOPVs with a keen interest in their various configurations, semitransparency, and outdoor and indoor applications. It describes the not-well-understood QOPV's general working mechanism. This review explores high-performance QOPVs based on the fourth component's contribution as a donor, acceptor, or dye molecule and beyond in photovoltaic applications. Finally, there is a discussion around QOPV's outlook and projected future research directions in this field. This review intends to provide an overview of the quaternary systems approach to OPVs and inform current and future researchers on investigating the full spectrum of OPVs.

多组分有机混合系统:四元有机光伏技术综述
在有机光伏(OPV)的二元混合活性层中嵌入第三和/或第四种成分,是实现高性能光伏电池和模块的一种很有前途的方法。这种多组分策略有利于通过附加成分扩大吸收范围。四元 OPV(QOPV)混合物由四种成分组成,有三种可能的配置:(i) 一个供体和三个受体,(ii) 两个供体和两个受体,或 (iii) 三个供体和一个受体。虽然与 OPV 中的其他系统相比,四元系统的研究相对较晚,但利用四种成分的协同效应,可实现创纪录的功率转换效率,目前已接近 20%。QOPV 为兼容性和电荷转移机制通道提供了充足的材料选择,可能会导致形态和取向的优化。回顾 QOPV 的最新进展对于了解其对 OPV 领域的贡献至关重要。本综述主要讨论了 QOPV 的研究进展,并对其各种配置、半透明性、室外和室内应用产生了浓厚的兴趣。综述描述了尚未被充分理解的 QOPV 的一般工作机制。本综述根据第四种成分作为供体、受体或染料分子及其他光电应用的贡献,探讨了高性能 QOPV。最后,还围绕 QOPV 的前景和该领域的未来研究方向进行了讨论。这篇综述旨在概述四元系统方法在 OPV 中的应用,并为当前和未来的研究人员研究 OPV 的所有方面提供信息。
