摘要
A photovoltaic device includes: a p-type diffusion layer (11) and a n-type diffusion layer (12) on a back face of a semiconductor substrate (1); electrodes (4 to 6); and a wiring board (8). The electrodes (4, 6) are disposed on the p-type diffusion layer (11), and the electrodes (5) are disposed on the n-type diffusion layer (12). The wiring board (8) has wires (82) connected to the electrodes (4, 6) by conductive adhesive layers (7) and wires (83) connected to the electrodes (5) by the conductive adhesive layers (7). The electrodes (6) are disposed, on both ends of the n-type diffusion layer (12) with respect to the x-axis direction, between an end region of the n-type diffusion layer (12) and an edge of the semiconductor substrate (1).
