Abstract
Described herein are various technologies pertaining to provision of energy to a rechargeable battery of a mobile electronic device. The mobile electronic device has an array of photovoltaic cells embedded therein or affixed thereto. The array of photovoltaic cells is electrically connected to the rechargeable battery of the mobile electronic device. A charging pad includes an array of optical emitters, which are configured to emit light when the mobile electronic device rests on or adjacent to the charging pad. A remotely situated light source acts as a luminaire and emits a directed beam of light towards the mobile electronic device to provide energy to the rechargeable battery.
