A luminescent solar concentrator-based photovoltaic system (LSC-PVs) is transparent because it harvests solar light through the LSC, a transparent panel containing only fluorophores. Because of this reason, LSC-PVs is promising as a PV window. Here, we demonstrate an LSC-PVs, which is based on the combination of an upconversion (UC)- assisted dual band harvesting LSC and perovskite solar cells (PSCs) for the practical use of LSC-PV. We arrange a dual LSC panel consisting of a downshift (DS) LSC that convert violet light into red light. The dual LSCs coupled with a PSC exhibit a high average-visible-transmittance (AVT) 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%. |
