NOVELTY - Photovoltaic semiconductor apparatus (10) comprises two adjacent oppositely doped volumes (12, 14) of semiconductor material that forms a semiconductor heterojunction (16), where first volume acts as emitter with front side for receiving light; first passivation material layer (20) on front side having a first outer surface (22) and openings (24-32) defining corresponding unpassivated areas of front side that are unpassivated by first passivation layer; and first conductive anti-reflective coating (44) on first outer surface of passivation layer and on unpassivated areas of front side.    USE - A photovoltaic semiconductor apparatus used in forming a solar cell (claimed) useful for converting light energy into electrical energy.    ADVANTAGE - The shallow emitter is uniform in thickness, thus there is no need to selectively form emitter areas of different thicknesses. Since the emitter is shallow, the apparatus is more responsive to blue light, thus making the overall device more efficient in converting light energy into electrical energy. Screen printing technology is not required, which eliminates several time and energy consuming manufacturing steps and reduces susceptibility to bowing that can be caused by use of conductive pastes on the front and back surfaces of the cell. The avoidance of screen printing technology allows solar cells to be manufactured more quickly and at less cost, and allows the formation of thinner emitters without risk of emitter shunting. The combination of passivation layer and anti-reflective coating facilitates efficient current collection. The use of coating precisely aligns the conductors on electrodes with pre-printed contacts, thus enabling a relaxation of manufacturing tolerances in solar cell manufacturing, which further decreases production costs.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of making a photovoltaic semiconductor apparatus.
