Photoelectric solar cell for photovoltaic generator

摘要

The solar cell (2) is based upon a carrier substrate (1) and has a solid state element (3) that responds to emissions on both surfaces. The surfaces have an electrically conducting track system (4,5) and one has an electrical connector (6). On the top surface of the solar cell is a transparent glass cover (7) which is adhesively bonded (8). Between the solid state element and the carrier substrate is a reflective layer (9) in the form of a foil, e.g. aluminium. The elements are bonded together (10). Incident infra-red emission (IR) is reflected by the foil and avoids an increase in temp. of the substrate.
