Photovoltaic device and solar module having a partial transparency

摘要

The specification discloses a photovoltaic device comprising a transparent, electrically insulating substrate, a plurality of photoelectric conversion elements using thin-layer technology, disposed as a stack on the substrate, these photoelectric conversion elements comprising a layer of material forming an opaque electrode traversed by cuts or openings, the latter advantageously exhibiting a groove shape which is elongate in a transverse direction of the cell and forming between them bands of material which are favorably oriented in the direction of the photogenerated current lines. A reinforced insulation of the cuts by a protective shoulder between layers may be provided. The invention permits partial-transparency solar cells or modules to be obtained.
