Photovoltaic device and solar module having a partial transparency

A solar module comprising:

• a plurality of elementary photovoltaic cells electrically connected in series;
• said cells being formed on an electrically insulating, transparent substrate, each cell comprising a plurality of photosensitive elements laminated on said substrate;
• said photosensitive elements including an opaque electrically conductive layer through which continuous parallel grooves are formed to allow light to be received by the module for passage therethrough, said grooves extending longitudinally, substantially parallel to each other, the distance between two successive grooves being less than or equal to substantially 2.5 mm.

A solar module for producing photogenerated current comprising:

• a plurality of elementary photovoltaic cells electrically connected in series;
• said cells being formed on an electrically insulating, transparent substrate, each cell comprising a plurality of photoelectric conversion elements laminated on said substrate;
• said photosensitive elements including a layer of opaque electrically conductive material through which longitudinal grooves are formed to allow light to be received by the module and pass therethrough, the photogenerated current flowing in said conductive layer along a predetermined direction, said grooves extending longitudinally without discontinuity, parallel to each other and to said direction of the photogenerated current, from a first end of said layer up to a second opposite end, thereby dividing said opaque conductive layer into a series of continuous bands.
