Abstract: 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

Abstract: An isolator for DC electrical power supply source, including: a blade movable along a travel between a conduction position and an isolating position, driving of the blade along its travel breaking a first electrical conductor, configured to conduct current from a DC supply source, into two mutually electrically insulated portions; a pressurized gas source selectively driving the blade along its travel; a pyrotechnic element including a detonator triggered by external command and an explosive whose explosion is initiated by the detonator, explosion of the explosive inducing the driving of the blade by the gas source.

Abstract: The invention relates to a solar receiver module for a concentrated photovoltaic (CPV) power plant, comprising a first optic, referred to as primary optic, consisting of a Fresnel lens, at least one second optic, referred to as secondary optic, having a straight frusto-conical shape or straight frusto-pyramidal shape, arranged below the primary optic, at least one photovoltaic cell arranged below a secondary optic, in order to receive the solar rays concentrated by the primary optic and said secondary optic, the receiver module also including temperature sensors for measuring temperature differences between a reference temperature and at least four points regularly distributed around the axis connecting the centre of the bases of the frustum of the cone or pyramid of a secondary optic, in order to produce a thermal cartography of same.
