Abstract

Perovskite photovoltaics (PPV), due to their compatibility with a flexible substrate, low cost, and high indoor performance compared to existing inorganic and organic photovoltaic technologies, are emerging as a potential candidate to power the internet of things (IOT). Dual-cation and mixed halide...
