PURPOSE:To obtain the amorphous Si solar cell applicable to various power simply by forming a plurality of beltlike conductive layers to the other end from one end of an insulating substrate and overlapping a conductive layer consisting of different quality of material extending over the whole longitudinal region except one part of the width of a belt. CONSTITUTION:A transparent electrode 10 is evaporated onto a glass plate 9 ane etched selectively, electrode layers 10' are formed at regular intervals, and Al 11 is evaporated selectively to the one parts. When amorphous Si thin-films 12 are deposited in order of a pin type, Al 11 diffuses among the thin-films and reaches up to the surfaces of the thin-films 12, and diffusion layers 13 are formed. Al layers 14 are formed adjacent to the layers 13, and sections among elements are connected in series, and used as the back electrodes of adjacent elements at the same time. Electrode leads 15, 16 are fitted to elements at both ends. According to said constitution, outputs can be varied freely without changing a mask, and the solar cell, a utilization rate of the substrate therein is high, is obtained. |
