Advancements in perovskite solar cell concentrators and future prospects

Abstract

Perovskite solar cells (PSCs) have emerged as a promising technology for converting solar energy into electricity, owing to their high efficiency and multifunctionality. In recent years, the focus of research has shifted toward the development of tandem or concentrator systems for the purpose of enhancing energy conversion efficiency and increasing power density. Concentrators increase the optical path length and light absorption within solar cells, thereby offering a viable solution for harnessing solar energy more efficiently. Recently, concentrator perovskite systems have shown a light-to-energy conversion efficiency of 27.3%, which exceeds that of the best-performing single junction PSCs. This review provides a comprehensive analysis of the recent advancements in the field of perovskite concentrated photovoltaics (P-CPVs) and prospects. The fundamental mechanisms driving the enhanced performance of PSCs under high-intensity light conditions were discussed. Furthermore, the review examines key aspects such as the design of concentrator optics, advancements in perovskite composition optimization, and notable device progress in the P-CPV area. Additionally, we overview strategies for improving heat dissipation and enhancing the overall efficiency of P-CPVs, along with the potential integration of tandem solar cells into concentrator photovoltaic systems.
