Semitransparent organic solar cells (ST-OSCs) offer unique features such as spectral tunability and see-through function, giving them great potential in photovoltaic (PV) agriculture. However, the combination of sufficient average visible transmittance (AVT) and high power conversion efficiency (PCE) with eco-friendly device fabrication has always been a key issue. Herein, a simple but effective strategy by incorporating pentacyclic aromatic lactam acceptor unit (TPTI) in copolymer donors for toluene processed high-efficiency ST-OSCs is performed. The comparisons between D18- and DEH-X-based ST-OSCs demonstrate the effect of TPTI inserting on the polymer main skeleton can not only lower the energy level, improve the processability in nonhalogen solvent, tune the ideal morphology for efficient charge dissociation, but also control a photon transport window suitable for plant absorption. Therefore, the resulting OSCs processed with toluene exhibit a PCE of 14.6% with an AVT of 22%, which represents one of the highest values for ST-OSCs made from nonhalogenated solvents. What's more, it is found that plant growth under ST-OSCs filtered light is comparable with that under natural light. Herein, a guide for developing high-performance ST-OSCs is provided and the prospect of ST-OSCs for green manufacturing PV greenhouse application is demonstrated.

高效半透明有机太阳能电池采用含五环芳族内酰胺的三元共聚物策略用于生态友好型温室应用

半透明有机太阳能电池 (ST-OSC) 具有光谱可调性和透视功能等独特特性，使其在光伏 (PV) 农业中具有巨大潜力。然而，将足够的平均可见光透射率 (AVT) 和高功率转换效率 (PCE) 与环保器件制造相结合一直是一个关键问题。在此，通过在甲苯处理的高效 ST-OSC 的共聚物供体中加入五环芳族内酰胺受体单元 (TPTI)，实施了一种简单但有效的策略。基于 D18 和 DEH-X 的 ST-OSC 之间的比较表明，在聚合物主骨架上插入 TPTI 的效果不仅可以降低能级，改善在非卤素溶剂中的加工性，调整有效电荷离解的理想形态，还要控制适合植物吸收的光子传输窗口。因此，用甲苯处理所得 OSC 的 PCE 为 14.6%，AVT 为 22%，这是由非卤化溶剂制成的 ST-OSC 的最高值之一。更重要的是，发现植物在 ST-OSCs 过滤光下的生长与在自然光下的生长相当。在此，提供了开发高性能 ST-OSC 的指南，并展示了 ST-OSC 在绿色制造光伏温室应用中的前景。发现植物在 ST-OSCs 过滤光下的生长与在自然光下的生长相当。在此，提供了开发高性能 ST-OSC 的指南，并展示了 ST-OSC 在绿色制造光伏温室应用中的前景。发现植物在 ST-OSCs 过滤光下的生长与在自然光下的生长相当。在此，提供了开发高性能 ST-OSC 的指南，并展示了 ST-OSC 在绿色制造光伏温室应用中的前景。
