| 摘要 |
A thin-film solar cell includes an insulating flexible substrate, a plurality of photoelectric conversion regions each having a rear electrode layer, an amorphous semiconductor layer and a transparent electrode layer, formed in this order on a first surface of the substrate, and a connecting electrode layer formed on a second surface of the substrate, so as to extend over two adjacent photoelectric conversion regions. The rear electrode layer is connected with the connecting electrode layer, through extended parts thereof deposited on an inner wall of a first hole formed through the rear electrode layer, substrate and the connecting electrode layer. The amorphous semiconductor layer includes an extended portion covering a surface of a portion of the connecting electrode layer located on a periphery of the first hole. The transparent electrode layer of one of two adjacent photoelectric conversion regions is connected with the connecting electrode layer, through extended parts thereof deposited on an inner wall of a second hole formed through the transparent electrode layer, amorphous semiconductor layer, rear electrode layer, substrate and connecting electrode layer, whereby the photoelectric conversion regions are connected in direct series with each other.
