Owing to their unique porosity and large surface area, porous organic polymers (POPs) have shown their presence in numerous novel applications. The tunability and functionality of both the pores and backbone of the material enable its suitability in photovoltaic devices. The porosity induced host-guest configurations as well as periodic donor-acceptor structures benefit the charge separation and charge transfer in photophysical processes. The role of POPS in other critical device components, such as hole transporting layers and electrodes, has also been demonstrated. Herein, this review will primarily focus on the recent progress made in applying POPs for solar cell device performance enhancement, covering organic solar cells, perovskite solar cells, and dye-sensitized solar cells. Based on the efforts in recent years in unraveling POP's photophysical process and its relevance with device performances, an in-depth analysis will be provided to address the gradual shift of attention from an entirely POP-based active layer to other device functional components. Combining the insights from device physics, material synthesis, and microfabrication, we aim to unfold the fundamental limitations and challenges of POPs and shed light on future research directions.
由于其独特的多孔性和大的表面积，多孔有机聚合物（POPs）在许多新的应用中表现出了它们的存在。材料的孔和骨架的可调节性和功能性使其适用于光伏器件。孔隙诱导的主体-客体结构以及周期性的供体-受体结构有利于光物理过程中的电荷分离和电荷转移。POPs 在其他关键器件组件中的作用，如空穴传输层和电极，也已经得到了证明。本文主要集中讨论了近年来在利用 POPs 来提高太阳能电池器件性能方面所取得的进展，涵盖有机太阳能电池、钙钛矿太阳能电池和染料敏化太阳能电池。基于近年来在揭示 POP 的光物理过程及其与器件性能相关性方面的努力，我们将进行深入分析，以探讨人们关注的焦点从完全基于 POP 的活性层逐渐转移到其他器件功能组件。结合器件物理、材料合成和微制造方面的见解，我们旨在揭示 POP 的基本局限性和挑战，并为未来的研究方向提供启示。
