Metal halide perovskites are a promising material system for wireless energy harvesting due to their amenability to flexible form factors offering high power per weight as well as their potential for low cost via high-speed manufacturing. We present an investigation of the performance of high-efficiency planar double cation perovskite solar cells in harvesting monochromatic illumination via Sentaurus TCAD simulations and experimental validation. We provide an examination of metal halide perovskites under a wide range LED illumination profiles in the μW - mW / cm<sup>2</sup> range, experimentally demonstrating a power conversion efficiency (PCE) above 37 %. Our TCAD simulations provide design rules for engineering wide bandgap perovskite cells to maximize wireless power transmission (WPT) for a given monochromatic source. These results also reveal the device physics limiting efficiency for low-intensity constant illumination and very high intensity pulsed illumination profiles. Based on these results, we model perovskite solar cells’ potential for high-efficiency medium to long range power transfer at 10 m – 500 m for power levels of 1 mW to 1 W, directly comparing the efficiency against alternative inductive WPT. These results suggest the promising role of perovskite solar cells in powering a more sustainable, battery-free future of the Internet of Things (IoT).
