Abstract
A new photovoltaic device includes at least one front emitter made of a p- or n-doped semiconductor material, coupled with at least one rear part made of an n- or p-doped semiconductor material, wherein the front part of the emitter is connected to a plurality of contacts located at the back of the device by means of one or more diffuser elements in the shape of plates, ducts or generic elements in relief made of p- or n-doped semiconductor material, which extend from the front part of the emitter through all or part of the n- or p-doped part.
Claims5
A photovoltaic device comprising:
- at least one front emitter made of a p- or n-doped semiconductor material;
- and
- at least one rear part made of an n- or p-doped semiconductor material, the at least one rear part being electrically coupled to the at least one front emitter,
- wherein a front part of said at least one front emitter is electrically connected to a plurality of contacts located at the rear of the device via one or more diffuser elements in the shape of plates, ducts, or generic elements in relief, the one or more diffuser elements being made of p- or n-doped semiconductor material and extending from said front part of the at least one front emitter through all or part of said rear part.
