New solar energy harvesting materials for indoor photovoltaics

Emerging organic and hybrid perovskite photovoltaics (PVs) are promising solar energy harvesting technologies for decentralized solar energy. Organic and perovskite semiconductors possess formidable optoelectronic properties, are easily solution-processed, adaptable to hot climates, and can be ultra-thin and semitransparent. They exhibit other advantages due to their flexibility, lightweight, and absorption tunability, making them suitable for unconventional applications, including the Internet of Things nodes, agrivoltaic, and indoor PV. Organic and perovskite PV exhibit record efficiencies of over 20% and 27%, respectively, at the cell level. Here, we will focus on recent developments and their indoor PV applications.
