Power generation module and method for manufacturing power generation module

A power generation module comprising:

• a first substrate having a light-transmitting property;
• a second substrate having a light-transmitting property, the second substrate facing the first substrate in a thickness direction of the first substrate;
• and
• a first submodule and a second submodule positioned side by side in a first direction intersecting the thickness direction between the first substrate and the second substrate, wherein:
• each of the first submodule and the second submodule has a base member and a solar cell disposed on the base member;
• the solar cell has a first electrode layer stacked on the base member, a semiconductor layer stacked on the first electrode layer, and a second electrode layer stacked on the semiconductor layer;
• and
• the first submodule and the second submodule have different dimensions in at least one of the first direction or a second direction intersecting both the thickness direction and the first direction.

A method for manufacturing a power generation module, comprising:

• preparing a first substrate having a light-transmitting property and having an L-shape or a T-shape;
• preparing a second substrate having a light-transmitting property;
• preparing a first submodule and a second submodule, each of the first submodule and the second submodule having a base member and a solar cell disposed on the base member;
• arranging the first submodule and the second submodule densely on one main surface of the first substrate, the first submodule and the second submodule being aligned in a first direction intersecting a thickness direction of the first substrate, the second submodule having different dimensions in at least one of the first direction or a second direction intersecting both the thickness direction and the first direction;
• and
• disposing the second substrate facing first substrate in the thickness direction, the first submodule and the second submodule being positioned between the second substrate and the first substrate, wherein
• the solar cell has a first electrode layer stacked on the base member, a semiconductor layer stacked on the first electrode layer, and a second electrode layer stacked on the semiconductor layer.
