Perovskite‐Inspired Cs₂AgBi₂I₉: A Promising Photovoltaic Absorber for Diverse Indoor Environments (Adv. Energy Mater. 7/2025)

Indoor Photovoltaics

Developing versatile absorbers for indoor photovoltaics (IPVs) to adapt to various lighting conditions in different indoor environments is crucial for advancing IPVs. In article number 2404547, Saswata Bhattacharya, K. D. M. Rao, Paola Vivo, and co-workers present Cs₂AgBi₂I₉, a new absorber with unique optoelectronic properties compared to other bismuth-based perovskite-inspired materials. Cs₂AgBi₂I₉-based IPVs display high performance under various LED light colours, from warm to cold white.
