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.

Abstract

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.
