In recent years, luminescent solar concentrators (LSCs) have gained a renaissance as a pivotal transparent photovoltaic (PV) for building-integrated photovoltaics (BIPVs). However, most of the studies focused on light-selective LSCs, and less attention was paid to the utilization of the full solar spectrum. In this study, a lead-free microcrystal CsAgNaBiInCl (CANBIC) perovskite phosphor is demonstrated to have bifunctional effects of luminescent down-shifting (LDS) and light scattering for the fabrication of LSCs, realizing light response from ultraviolet (UV) to NIR regions by an edge-mounted Si solar cell.

- Light management (LM) is crucial for improving the performance of encapsulated silicon photovoltaic devices, with simulations highlighting optical losses and pathways for enhancement.
- An antireflective layer made of textured polydimethylsiloxane (PDMS) reduces reflection losses, boosting short-current density by 10.89% and power conversion efficiency (PCE) by 12.67% at a 60° incident angle.
- Incorporating a lead-free luminescence down-shifting material (CsAgNaBiInCl) into the PDMS film further increases PCE from 21.770% to 23.136%, achieved through reduced reflection and enhanced UV energy conversion.
Colloidal AgInS/ZnS quantum dots (QDs) have recently emerged as a promising, efficient, nontoxic, down-shifting material in optoelectronic devices. These QDs exhibit a high photoluminescent quantum yield and offer a range of potential applications, specifically in the field of photovoltaics (PVs) for light management. In this work, we report an eco-friendly method to synthesize AgInS/ZnS QDs and deposit them on commercial silicon solar cells (with an active area of 7.
