Perovskite-Based Photovoltaics for Artificial Indoor Light Harvesting: A Critical Review

Abstract

Under artificial indoor light, the development of efficient photovoltaics has attracted massive attention due to the revolutionary growth involving the Internet of Things for riding low-power wireless electronic gadgets. Among the variety of available photovoltaic technologies such as inorganics (i.e., silicon, copper indium gallium selenide, cadmium telluride), organic photovoltaics, and hybrid organic-inorganic perovskites photovoltaics (PPVCs), the PPVCs have been recognized as the most promising PVCs for indoor light energy harvesting applications. This suitability is related to various factors due to its significant absorption coefficient, tunable bandgap, remarkable defect tolerance, better optoelectronic properties, and straightforward fabrication process. However, several parameters interconnected to materials, processing conditions, architecture, and indoor characterizations need to be optimized to enhance indoor photovoltaic efficiency, stability, and eco-friendly nature. This review summarizes the latest research trends on organic-inorganic perovskite material-based indoor PVCs, including the impact of composition tuning, choice of many practical layers, and device structures on their performance. Various challenges are highlighted to address before these indoor PPVCs are available in the commercial market.
