Organic thin-film solar cell module and sub-module

摘要

An organic thin-film solar cell module according to one embodiment includes solar cell panels and reflective surfaces. Each panel includes a substrate, a 1st electrode, a 2nd electrode and a photoelectric conversion layer. When supposing a 1st plane including the reflective surface, a 1st intersection line as a line of intersection of the 1st plane and the 2nd main surface of the substrate, and a 2nd plane including the 1st intersection line and forming an angle of 45° with the 2nd main surface of the substrate and an angle smaller than 45° with the 1st plane, an edge of the photoelectric conversion layer is in contact with the 2nd plane or the 2nd plane intersects the photoelectric conversion layer.

1. An organic thin-film solar cell module comprising:
a plurality of solar cell panels, each 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; a plurality of reflective surfaces, each obliquely facing a portion of the second main surface of each solar cell panel; and bus bars each disposed on the substrate of the solar cell panel, each of the bus bars being electrically connected to the second electrode and made of a material whose electric conductivity is higher than that of the second electrode, wherein a first plane including the reflective surface and intersecting with the second main surface of the substrate, an intersection line at which the first plane intersects with the second main surface of the substrate, and a second plane including the intersection line and forming an angle of 45° with the second main surface of the substrate and forming an angle smaller than 45° with the first plane are defined so that the second main surface of the substrate of the solar cell panel receives incident light from the reflective surface mainly in an oblique direction, an edge of the reflective surface directing toward the second main surface of the substrate is not in contact with the second main surface to provide a gap between them, the second plane intersects with the solar cell panel to divide the solar cell panel into a first region on which incident light falls and a second region on which incident light does not fall, the first region and the second region bordering on each other in the solar cell panel, the photoelectric conversion layer is provided in the first region and an edge of the photoelectric conversion layer adjacent to the second region is in contact with the second plane, and the bus bar is disposed on the second region.
