In a photovoltaic device (1), first amorphous semiconductor portions (102n) and second amorphous semiconductor portions (102p) are provided alternately on one of faces of a semiconductor substrate (101). Each first amorphous semiconductor portion (102n) has at least one first amorphous semiconductor strip (1020n), and each second amorphous semiconductor portion (102p) has at least one second amorphous semiconductor strip (1020p). A plurality of first electrodes (103n) are provided spaced apart from each other on each first amorphous semiconductor strip (1020n), and a plurality of second electrodes (103p) are provided spaced apart from each other on each second amorphous semiconductor strip (1020p).
