Organic thin-film solar cell module and sub-module

An organic thin-film solar cell sub-module comprising:

• a solar cell panel comprising a substrate with first and second main surfaces, a first electrode facing the first main surface, a second electrode interposed between the substrate and the first electrode, and a photoelectric conversion layer interposed between the first and second electrodes;
• and
• a reflective surface, the solar cell panel and the reflective surface being arranged such that back sides thereof obliquely face each other,
• wherein the sub-module has a structure that allows two or more sub-modules assembled into an organic thin-film solar cell module in which the reflective surface of each sub-module obliquely faces a portion of the solar cell panel of the adjacent sub-module, and when supposing, in each combination of the solar cell panel and the reflective surface obliquely facing each other, a first plane including the reflective surface, a first intersection line as a line of intersection of the first plane and the second main surface of the substrate, and a second plane including the first intersection line and forming an angle of 45° with the second main surface of the substrate and an angle smaller than 45° with the first plane, an edge of the photoelectric conversion layer is in contact with the second plane or the second plane intersects the photoelectric conversion layer.

A solar cell module comprising:

• solar cell panels each including a substrate with first and second main surfaces, a first electrode facing the first main surface, a second electrode interposed between the substrate and the first electrode, and a photoelectric conversion layer interposed between the first and second electrodes, wherein the solar cell panels are arranged in a first direction with a gap therebetween such that the first main surface makes an angle with the first direction;
• and
• reflective surfaces alternating with the solar cell panels in the first direction, each of the reflective surfaces being perpendicular to a plane including the first direction and a second direction perpendicular to the second main surface and obliquely facing the second main surface, wherein when supposing first to third planes in a combination including one of the solar cell panels and one of the reflective surfaces obliquely facing each other, the first plane including the reflective surface of the combination, the second plane including the second main surface of the substrate of the solar cell panel of the combination, and the third plane being one of two planes including a line of intersection of the first and second planes and making an angle of 45° with the second plane that makes a smaller angle with the first plane, the third plane is in contact with or extends across the photoelectric conversion layer.
