Abstract

A photovoltaic module, configured for inclined (with respect to the horizontal surface) installation at a chosen latitude as part of rows of such photovoltaic modules, is complemented with a diffractive element that is configured to form a combination in which a gap between neighboring rows is bridged by the diffractive element to diffract sunlight incident onto so installed diffractive element towards the photovoltaic module. The photovoltaic module and the diffractive elements can be connected to one another in a turnable fashion, for example through hinge, to enable electrical power generation that is substantially time-invariable throughout a portion of a year. Photovoltaic module optionally includes internal holographically-defined diffraction gratings and/or bifacial photovoltaic cells.
