Title: MULTIFUNCTIONAL STATIC OR SEMI-STATIC PHOTOVOLTAIC SKYLIGHT AND/OR METHODS OF MAKING THE SAME
Abstract:
Improved building-integrated photovoltaic systems according to certain example embodiments may include concentrated photovoltaic skylights or other windows having a cylindrical lens array. The skylight may include an insulated glass unit, which may improve the Solar Heat Gain Coefficient (SHGC). The photovoltaic skylight and lens arrays may be used in combination with strip solar cells. Arrangements that involve lateral displacement tracking systems, or static systems (e.g., that are fixed at one, two, or more predefined positions) are contemplated herein. Such techniques may advantageously help to reduce cost per watt related, in part, to the potentially reduced amount of semiconductor material to be used for such example embodiments. A photovoltaic skylight may permit diffuse daylight to pass through into an interior of a building so as to provide lighting inside the building, while the strip solar cells absorb the direct sunlight and convert it to electricity, providing for SHGC tuning.
