Photoelectric conversion device and method for fabricating the photoelectric conversion device

A method for fabricating a photoelectric conversion device, the method including:

• forming a plurality of photoelectric conversion cells on a main surface of a substrate;
• forming a current-collecting wiring for collecting currents generated by the plurality of photoelectric conversion cells;
• forming an output wiring for outputting power generated by the current-collecting wiring to the outside;
• and
• bonding a back-side protective member to the plurality of photoelectric conversion cells via sealing member in a manner such that the plurality of photoelectric conversion cells are interposed between the substrate and the back-side protective member via the sealing member,
• wherein the current-collecting wiring and the output wiring are positioned and connected such that the current-collecting wiring and the output wiring do not overlap with each other above the main surface of the substrate, and
• wherein at least one of the current-collecting wiring and the output wiring has asperities on a joint surface between the current-collecting wiring and the output wiring.
