Abstract
An optical collection apparatus includes a plurality of light transmissive optical reflectors and a plurality of planar bifacial solar cells. Each light transmissive optical reflector is configured to transmit indirect light impinging on first and second collection sides thereof. First and second photovoltaic sides of each of the plurality of bifacial solar cells are positioned to collect indirect light impinging thereon. The planar bifacial solar cells are arranged such that at least one light transmissive optical reflector of the plurality of light transmissive optical reflectors is positioned between consecutive ones of the planar bifacial solar cells. Each light transmissive optical reflector of the plurality of light transmissive optical reflectors is configured to reflect direct incoming light impinging on the first collection side thereof towards the first photovoltaic side of a corresponding one of the planar bifacial solar cells. A solar collection and shading system is also contemplated.
