PHOTOVOLTAIC OPTICAL DEVICE WITH BIFACIAL PLASMONIC FILTRATION AND MULTIREFRINGENCE VARIABLE REAR SINGLE CONVEX AND DUAL CONCAVE LOCALLY

摘要

Photovoltaic optical device with bifacial plasmonic filtration and variable rear multirefringence convex and double concave locally characterized in that it comprises: - rows of crystalline bifacial solar cells (1) having a front surface (1f) and a rear surface (1r) of photovoltaic conversion ratio of 80% minimum and interconnected to form a matrix (2) encapsulated between an incoming (4) and outgoing (7) diopter whose distance (e) separating two rows is equal to or smaller than the segment of a cell solar (1) - The surface taken in the plane of the matrix (2) forms an area (2s) - a plasmonic filter (3) stuck on the incoming diopter (4) and positioned in parallel with a row of solar cells ( 1) in the interval (e) separating the solar cells (1) and centered on the median axis between two rows of cells so 1/2 of (e) - A light transmission area (6S) consisting of the interval (e) by a r solar cell angle (1) - A variable convex and double concave locally variable mirror (8) variable multirefringent filter (8c) adhered to the lower surface (7 ") of the outgoing diopter (7) covering the lower surface (7") of a surface equal to the area (2s) and in which the single convex and double concave zone (8c) of the filter (8) is positioned exactly in parallel superposition at any point of the area (6S) to reflect the light rays towards the rear face (1r) of the solar cells and to the plasmonic filter (3) by divergence of the diffracted radii of the simple convex dichroic mirror (8c) and by convergence of the diffracted radii of the double concave dichroic mirror The median axis of the convex simple form the optical filter (8) must be positioned exactly and coincident with the median axis between two rows of solar cells (1) and the median axis of the plasmonic filter (3).
