A series of opaque and semitransparent polymer solar cells (PSCs) were fabricated with PM6:Y6 as active layers, and 100 nm Al or 1 nm Au/(20, 15, 10 nm) Ag layer as electrode, respectively. The power conversion efficiency (PCE) of opaque PSCs arrives to 15.83% based on the optimized active layer with a thickness of 100 nm, resulting from the well-balanced photon harvesting and charge collection. Meanwhile, the 100 nm PM6:Y6 blend film exhibits a 50.5% average visible transmittance (AVT), which has great potential in preparing efficient semitransparent PSCs. The semitransparent electrodes were fabricated with 1 nm Au and different thick Ag layers, exhibiting a relatively high transmittance in visible light range and relatively low transmittance in near infrared range. The PCE and AVT of the semitransparent PSCs can be adjusted from 14.20% to 12.37% and from 8.9% to 18.6% along with Ag layer thickness decreasing from 20 to 10 nm, respectively, which are impressive values among the reported semitransparent PSCs.

以 PM6:Y6 作为活性层，分别以 100 nm Al 或 1 nm Au/(20, 15, 10 nm) Ag 层作为电极，制备了一系列不透明和半透明的聚合物太阳能电池 (PSC)。基于优化后的厚度为 100 nm 的有源层，不透明 PSC 的功率转换效率 (PCE) 达到 15.83%，这得益于均衡的光子收集和电荷收集。同时，100 nm PM6:Y6 共混薄膜具有 50.5% 的平均可见光透射率 (AVT)，在制备高效半透明 PSC 方面具有巨大潜力。半透明电极由1 nm Au和不同厚度的Ag层制成，在可见光范围内表现出相对较高的透射率，在近红外范围内表现出相对较低的透射率。半透明 PSC 的 PCE 和 AVT 可以从 14.20% 调整到 12。
