Described herein is a system to convert laser light to electrical energy which exploits a narrow band nature of laser light, and a cavity resonance effect in order to increase an absorption of the laser light and thus, an efficiency in conversion of the laser light to electrical energy. For the resonant effect to take place in the photovoltaic cells, the laser wavelength emitted by the laser should match at least one of the resonant lines of the resonant cavity. A resonant cavity enhances an intensity of laser light inside the photovoltaic cell. The subject matter lowers a cost of the photovoltaic cell by making it possible to use a thinner (and more mechanically flexible) semiconductor for the photovoltaic cell while achieving the good laser light to power conversion efficiency.
