A thin film photovoltaic and thermal solar panel comprises thin film photovoltaic cells 12 deposited on a metal plate 13, to which are attached pipes 14 and/or fins (17, fig 4) to transfer heat to a circulating fluid. The photovoltaic cells 12 may be isolated from the metal plate 13 by a layer of insulating material (4, fig 1). The photovoltaic cells 12 acts as the front surface of the collector plate. Radiation not converted to heat is conducted to the metal plate 13. If a liquid heat transfer medium is used, metal pipes 14 or conduits are bonded to the metal plate, and the fluid circulates within these pipes or conduits. If the heat transfer medium is air, this air circulates above and/or below the metal plate 13. Fins (17) can be bonded to the plate underside to increase the surface area available for heat transfer. The panel is enclosed in a box, which includes insulation and cover glass, to reduce heat losses. |
