Abstract
This invention is concerned with reducing the operating temperature and increasing the output of a solar cell. A solar cell (10) constructed in accordance with the invention carries electrodes (22) in a grid finger pattern on its back surface (12). These electrodes are sintered at the proper temperature to provide good ohmic contact. After sintering, a reflective material (24) is deposited on the back surface by vacuum evaporation. Thus, the application of the back surface reflector is separate from the back contact formation. Back surface reflectors formed in conjunction with separate grid finger configuration back contacts are more effective than those formed by full back metallization of the reflector material.
