PHOTOVOLTAIC STRUCTURE

The invention relates to a photovoltaic structure comprising a first wall and a second wall defining an inner space therebetween, the first wall being at least partially transparent to solar radiation, the second wall comprising an inner surface that is at least partially reflective with respect to solar radiation across from the inner surface of the first wall, the first wall being part of a closed enclosure and the second wall being arranged inside said enclosure, and photovoltaic modules each comprising a plurality of bifacial photovoltaic cells, arranged on the outer surface of the first wall, such that when the structure is exposed to solar radiation, a first portion of the incident radiation is transmitted to the outer surface of said bifacial photo voltaic cells, and a second portion of said incident radiation is transmitted through a portion of the first wall and reflects at least partially on the inner surface of the second wall, said reflected portion being transmitted through the first wall to the inner surface of the bifacial photovoltaic cells.
