Title:
光電変換装置およびそれを備える太陽電池モジュール
Document Type and Number:
Japanese Patent JP6915054
Kind Code:
B2
Abstract:
A photovoltaic device including: a first amorphous semiconductor layer (3) and a second amorphous semiconductor layer (4) both on a back face of a semiconductor substrate (1); electrodes (5, 6); and a wiring board (8). The electrodes (5, 6) are disposed on the first amorphous semiconductor layer (3) and the second amorphous semiconductor layer (4) respectively. The wiring board (8) has wires (82) connected to the electrodes (5) by a conductive adhesive layer (7). The wiring board (8) has wires (83) connected to the electrodes (5) by the conductive adhesive layer (7). The electrodes (5) include conductive layers (51, 52). The electrodes (6) include conductive layers (61, 62). The conductive layers (51, 61) are composed primarily of silver. The conductive layers (52, 62) cover the conductive layers (51, 52) respectively. Each conductive layer (52, 62) is composed of a metal more likely to be oxidized than silver.
