To date, the power conversion efficiency (PCE) of lab‐scale organic solar cells (OSCs) has exceeded 17%, which heralds the bright future for commercial applications of OSCs. High‐performance OSCs with thick active layers are essential for large‐scale production. First, the relatively thick active layers should be more compatible with the roll‐to‐roll (R2R) large‐area processing, which is conducive to forming uniform and defect‐free active layers in the process of high‐speed, mass production. Second, the thick active layers can absorb more incident light in their spectral range, which helps thick‐film OSCs to obtain relatively high short‐circuit current density (JSC). So far, relatively little attention has been paid to thick‐film OSCs, and the PCE of thick‐film OSCs lags far behind its thin‐film analogues. Herein, the recent development of thick‐film OSCs is highlighted and the critical limit factors on the PCE of thick‐film OSCs are pointed out. Some strategies are highlighted to improve the efficiency of thick‐film OSCs. This review study will be helpful to the researchers engaging in the development of efficient thick‐film OSCs.

高效的厚膜有机太阳能电池的批判性评论
迄今为止，实验室规模的有机太阳能电池（OSC）的功率转换效率（PCE）已超过17％，这预示着OSC的商业应用前景广阔。具有厚有源层的高性能OSC对于大规模生产至关重要。首先，相对较厚的有源层应与卷对卷（R2R）大面积处理更兼容，这有利于在高速，批量生产的过程中形成均匀且无缺陷的有源层。其次，厚的有源层可以吸收更多的光谱范围内的入射光，这有助于厚膜OSC获得相对较高的短路电流密度（J SC）。到目前为止，对厚膜OSC的关注相对较少，而厚膜OSC的PCE远远落后于其薄膜类似物。在此，重点介绍了厚膜OSC的最新发展，并指出了影响厚膜OSC的PCE的关键限制因素。重点介绍了一些提高厚膜OSC效率的策略。这项综述研究将对从事高效厚膜OSC开发的研究人员有所帮助。
