Improving the overall characteristics of semitransparent solar cells (STSCs) is a very hard goal, not only because the absorption and the transmission of light through the device are two competitive processes but also because the power conversion efficiency (PCE) decreases with the angle of incidence of sunlight rays due to Fresnel law limits. Here, unprecedented single-junction perovskite STSCs have been fabricated thanks to rational management of the transverse magnetic and electric light reflection modes of a dielectric/metal/dielectric triple layer used as a top electrode. This approach allows an increase of the photocurrent density in a broad angular range of the sunlight incidence and the overall figure of merit of different kinds of perovskite-based solar cells including PCE and light utilization efficiency (LUE), as well as aesthetic properties such as the color rendering index (CRI) and CIELab chromaticity coordinates, thus showing a universal method for real building integration and agrivoltaic applications.

通过电极光学管理提高半透明钙钛矿太阳能电池整体性能的合理方法

提高半透明太阳能电池（STSC）的整体特性是一个非常困难的目标，不仅因为通过设备的光的吸收和传输是两个竞争过程，而且还因为功率转换效率（PCE）随着入射角的增加而降低由于菲涅尔定律的限制，太阳光线的数量。在这里，由于对用作顶部电极的介电/金属/介电三层的横向磁和电光反射模式的合理管理，制备出了前所未有的单结钙钛矿STSC。这种方法可以提高太阳光入射角范围内的光电流密度以及不同种类钙钛矿太阳能电池的整体品质因数，包括PCE和光利用率（LUE），以及美学特性，例如显色指数 (CRI) 和 CIELab 色度坐标，从而展示了实际建筑集成和农业光伏应用的通用方法。
