摘要

在过去的几十年里,有机太阳能电池(OSCs)领域的材料化学发生了重大发展,器件性能显著提高,效率超过 19%。有机太阳能电池中的光活性层材料在光吸收、电荷生成、传输和稳定性方面起着至关重要的作用。为了促进 OSCs 的放大,必须解决这些电子受体和供体材料的光稳定性问题,因为它们的光化学降解过程仍然是光电转换过程中的一项挑战。在本综述中,我们概述了电子受体和供体材料的发展,强调了其化学稳定性行为中与 OSC 光稳定性相关的重要方面。在每个章节中,我们都会重点介绍电子受体和供体材料的光化学降解途径,以及它们与器件降解之间的联系。我们还讨论了阻碍光稳定性材料开发的现有跨学科挑战和障碍。最后,我们深入探讨了旨在提高光化学稳定性的策略,并讨论了开发光稳定性光活性层的未来方向,以促进 OSC 的商业化。

Understanding photochemical degradation mechanisms in photoactive layer materials for organic solar cells

Over the past decades, the field of organic solar cells (OSCs) has witnessed a significant evolution in materials chemistry, which has resulted in a remarkable enhancement of device performance, achieving efficiencies of over 19%. The photoactive layer materials in OSCs play a crucial role in light absorption, charge generation, transport and stability. To facilitate the scale-up of OSCs, it is imperative to address the photostability of these electron acceptor and donor materials, as their photochemical degradation process remains a challenge during the photo-to-electric conversion. In this review, we present an overview of the development of electron acceptor and donor materials, emphasizing the crucial aspects of their chemical stability behavior that are linked to the photostability of OSCs. Throughout each section, we highlight the photochemical degradation pathways for electron acceptor and donor materials, and their link to device degradation. We also discuss the existing interdisciplinary challenges and obstacles that impede the development of photostable materials. Finally, we offer insights into strategies aimed at enhancing photochemical stability and discuss future directions for developing photostable photo-active layers, facilitating the commercialization of OSCs.
