Photovoltaic device and process for manufacturing the same.

摘要

The present invention discloses a process for manufacturing a photovoltaic device which comprises providing a plurality of spaced transparent electrode layer regions (21,22,23) on an insulating transparent substrate plate (1), forming an amorphous semiconductor layer (3) over the spaced transparent electrode layer regions, forming a patterned conductive printedeletrode layer (41,42,43) over the amorphous semiconductor layer to form a plurality of photovoltaic regions, and then irradiating the photovoltaic regions with a laser beam from the substrate plate side to heat and melt the transparent electrode, amorphous semiconductor, and conductive printed electrode in each photovoltaic region, thereby forming in each photovoltaic region a conductive path (51, 52) made of an alloy formed by the melting, thus electrically connecting the photovoltaic regions in series, and a photovoltaic device manufactured by the above process.
