Abstract

A system is set forth herein which can include a plurality of reflectors adapted to reflect light. The system can further include a plurality of photovoltaic cells. A certain reflector of the plurality of reflectors adapted to reflect light can be adapted to reflect light within a certain wavelength band and can be further adapted to transmit light outside of the certain wavelength band. A photovoltaic cell can be disposed to receive light reflected by the certain reflector.
