Photovoltaic Protective Case

This invention describes a protective phone case that has solar panels built into its back. These panels capture sunlight, convert it into electricity, and store it in a small internal battery. This stored energy is then wirelessly transferred to the phone, providing a continuous power source without needing a wall charger. The case is specifically designed as a back cover for smartphones and includes a wireless charging pad inside.

Why it matters: Improvements in small-scale solar panel efficiency and wireless power transfer technology since 2020 could make the continuous charging capability more effective and practical for mobile devices.
