PHOTOVOLTAIC ROOFING ELEMENT

摘要

Photovoltaic roofing elements generally impair the aesthetic appearance of a building as they do not follow the geometry of the tiles used for the roof. In addition, the imposed constraints, for preventing water from infiltrating into the areas of connection with the tiles, further accentuate this impairment. The invention remedies these drawbacks by maintaining the geometry of the tiles forming the roof and fully protects the photovoltaic element from the external environment and from ambient moisture. To do this, a transparent moulded glass tile, having on its lower surface, in the central portion thereof, a flat zone with a thickness of 6 to 20 millimetres receives a photovoltaic module, this module being attached to the glass and adhesively bonded thereto via a transparent polymer over its entire surface. The photovoltaic module may be formed from a module produced with cells made of polycrystalline silicon or cells in thin-film technology. In the case of a module in thin-film technology, an inverted structure, the rear face of which corresponds to the glass substrate serving as base substrate for the module, is advantageous.
