A photovoltaic module for converting laser radiation from a laser emitting light at a wavelength to electrical power is provided. The module comprises: (a) a housing having a cavity of generally optimized closed shape inside the housing, the cavity having an internal surface area As and including an opening for admitting the laser radiation into the cavity, the opening having an entrance aperture area Ai that is substantially smaller than As; and (b) a plurality of photovoltaic cells within the cavity, the photovoltaic cells having an energy bandgap to respond to the wavelength and generate the electrical power.
