Donor PM6 and acceptor L8-BO are employed to build semitransparent organic photovoltaics (ST-OPVs). Opaque OPVs are fabricated by tuning the spin-coating speed of PM6:L8-BO solution to optimize the photon utilization by balancing photon harvesting and photogenerated carrier collection. The optimal opaque OPVs exhibit relatively high fill-factor (FF) of 77.58% and power conversion efficiency (PCE) of 15.07%, the average visible transmittance (AVT) of corresponding PM6:L8-BO films arrives to 53.25%, indicating great potential in realizing efficient ST-OPVs. ST-OPVs are built with 1 nm Au/(10, 15, 20, 25 nm) Ag as cathode, exhibiting the PCE/AVT of 11.53%/22.57%, 13.20%/14.24%, 14.28%/9.34%, and 14.71%/6.77%, respectively. Colorful ST-OPVs are achieved by coupling different Ag/LiF/Ag Fabry-Pérot (F-P) resonator microcavity. Green ST-OPVs with varied color coordinates are achieved by fixing LiF layer thickness as 110 nm and varying Ag layers′ thickness, originating from the adjusted transmittance spectra of green ST-OPVs. Upon fixing Ag layers′ thickness as 15/25 nm and varying LiF layer thickness as 90, 110, and 145 nm, ST-OPVs present colors of blue, green, and red with corresponding transmittance peak at 474, 553, and 657 nm. The corresponding PCE/peak transmittance (Tpeak) values arrive to 13.80%/37.8%, 13.31%/28.4%, and 13.20%/27.7%, which should be the best performance among reported colorful ST-OPVs.

通过优化光子利用率和法布里-珀罗谐振器电极，记录关键参数的彩色半透明有机光伏
供体 PM6 和受体 L8-BO 用于构建半透明有机光伏 (ST-OPV)。不透明 OPV 是通过调整 PM6:L8-BO 溶液的旋涂速度来制造的，通过平衡光子收集和光生载流子收集来优化光子利用率。最佳的不透明OPV表现出相对较高的填充因子（FF）77.58％和功率转换效率（PCE）15.07％，相应PM6：L8-BO薄膜的平均可见光透过率（AVT）达到53.25％，显示出巨大的潜力实现高效的 ST-OPV。 ST-OPV 采用 1 nm Au/(10, 15, 20, 25 nm) Ag 作为阴极，PCE/AVT 分别为 11.53%/22.57%、13.20%/14.24%、14.28%/9.34% 和 14.71分别为 %/6.77%。彩色 ST-OPV 是通过耦合不同的 Ag/LiF/Ag Fabry-Pérot (FP) 谐振器微腔来实现的。具有不同颜色坐标的绿色 ST-OPV 是通过将 LiF 层厚度固定为 110 nm 并改变 Ag 层厚度来实现的，这源于调整后的绿色 ST-OPV 的透射率光谱。将Ag层厚度固定为15/25 nm并将LiF层厚度改变为90、110和145 nm时，ST-OPV呈现蓝色、绿色和红色，相应的透射率峰值位于474、553和657 nm。相应的PCE/峰值透过率（Tpeak ）值达到13.80%/37.8%、13.31%/28.4%和13.20%/27.7%，这应该是已报道的彩色ST-OPV中最好的性能。
