Organic solar cells (OSCs) with visible transparency and vivid colors are promising for deployment in building-integrated photovoltaics (BIPVs), yet significant challenges remain to be addressed for not only balancing the trade-off between the photovoltaic and optical properties but also controlling the bandpass of visible transmittance for the coloration of semitransparent OSCs (ST-OSCs). Herein ST-OSCs with vivid colors are successfully developed by employing one fixed active blend in the rationally designed device layout with a high-quality Fabry–Pérot electrode. With the assistance of optical simulation, vividly colorful ST-OSCs have been obtained with power conversion efficiency of >14% and maximum transmittance up to 31%. Overall, this study provides new access to OSCs with promising features as BIPVs.

色彩鲜艳的半透明有机太阳能电池

具有可见透明性和鲜艳色彩的有机太阳能电池（OSC）有望在建筑集成光伏（BIPV）中进行部署，但不仅要平衡光伏和光学特性之间的权衡，而且还要控制太阳能电池的使用，仍然存在重大挑战。用于半透明OSC（ST-OSC）着色的可见光透射率带通。在这里，通过在合理设计的设备布局中使用一种固定的活性混合物和高质量的Fabry-Pérot电极，成功开发了色彩鲜艳的ST-OSC。借助光学仿真，获得了色彩鲜艳的ST-OSC，功率转换效率> 14％，最大透射率高达31％。总的来说，这项研究为OSC提供了具有BIPV前景的新功能。
