Photon upconversion-assisted dual-band luminescence solar concentrators coupled with perovskite solar cells for highly efficient semi-transparent photovoltaic systems

Abstract

A luminescent solar concentrator-based photovoltaic system (LSC-PVs) is highly transparent because it harvests solar light via the LSC, a transparent panel containing only fluorophores, and is, therefore, promising as a PV window. However, for the practical use of LSC-PV, achieving high efficiency remains a challenge. Here, we demonstrate an LSC-PV, which is based on the combination of an upconversion (UC)-assisted dual band harvesting LSC and perovskite solar cells (PSCs). We prepare a dual LSC panel consisting of a downshift (DS) LSC that absorbs violet light and an LSC that upconverts the red light. We apply a highly efficient mixed halide PSC with an efficiency of 17.22%. We control the thickness of the LSC panel as well as the dye concentration to maximize the emission from dual LSCs. The dual LSCs coupled with a PSC exhibit a high average-visible-transmittance of 82% and achieve a maximum efficiency of 7.53% at 1 sun (AM 1.5G) illumination. The dual LSC–PSC exhibits a constant efficiency even under oblique solar light illumination and a stable operation with an efficiency retention of 80%.
