The equipment (1) is for the recovery of incoming light and its conversion into electrical energy with the use of photovoltaic cells. The equipment has a hermetically closed chamber (2) on a holder (4) and the chamber is at least partly limited by the holder and a light transparent plate (5) is opposite to the photovoltaic solar cells (3). The holder is completely covered by a gastight sheet (6) which is fixed along the periphery of the holder against the limiting parts (8) of the closed chamber. In the hermically closed chamber a vacuum or near-vacuum is produced. The sheet comprises several layers, on eof which is thermoplastic, which by heating is fixed against the limiting parts (8). |
