用于汽车和建筑应用的窗口集成光电池是有机太阳能组件的一个有前途的细分市场。除了半透明性，窗口集成应用还需要合理的透明度感知和良好的显色性，以适应真实场景照明。在此，发现通过包含聚合物/富勒烯共混物聚[（4，4 ′-双（2-乙基己基）二噻吩并[3，2-B：2 ′，3 ′-d]噻咯）-2，6-二基-alt（2，1，3-苯并噻二唑）-4，7-二基]：[6，6]-苯基C-71-丁酸甲酯（PSBTBT：PC 70 BM）作为活性层和溅射铝掺杂的氧化锌阴极的半透明有机太阳能电池的透射光表现出人眼的颜色中性感觉和非常好的显色性能。此外，电池特性允许有效的能量收集，总功率转换效率η接近3%。
Window integrated photovoltaics for automotive and building applications are a promising market segment for organic solar modules. Besides semi-transparency, window integrated applications require a reasonable transparency perception and good color rendering properties in order to be suitable for realistic scene illumination. Here, the transmitted light through semi-transparent organic solar cells comprising the polymer/fullerene blend poly[(4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2',3'-d]silole)-2,6-diyl-alt(2,1,3-benzothiadiazole)-4,7-diyl]: [6,6]-phenyl C-71-butric acid methyl ester (PSBTBT:PC70BM) as active layer and a sputtered aluminum doped zinc oxide cathode were found to exhibit a color neutral perception for the human eye and very good color rendering properties. Moreover, the electrical cell properties allow for efficient energy harvesting with an overall power conversion efficiency eta approximate to 3%.
