Indoor Perovskite Photovoltaics for the Internet of Things—Challenges and Opportunities toward Market Uptake

The high‐power conversion efficiency of flexible perovskite photovoltaics (PPV) at low light environment and their low‐cost manufacturing processes, render PPV superior to conventional rigid photovoltaics targeting indoor applications. However, various parameters related to materials, architecture, processing, and indoor characterization need to be optimized further toward improving indoor PPV (iPPV) efficiency, stability, and ecotoxicity. This...
