Abstract
Official abstract text for this publication.
A photoelectric conversion module is a photoelectric conversion module including a translucent substrate and one or more photoelectric conversion elements formed on the translucent substrate, wherein each of the photoelectric conversion elements is formed by stacking a transparent conductive film, a first charge transport layer, a power generation layer, and a second charge transport layer made of a porous film containing a carbon material, in this order from the side of the translucent substrate, and a portion of the second charge transport layer of at least one of the photoelectric conversion elements, the portion facing another transparent conductive film adjacent to the transparent conductive film of the photoelectric conversion element is electrically connected to the other transparent conductive film via a conductive layer that is thicker than a thickness of adding up the first charge transport layer and the power generation layer.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A photoelectric conversion module comprising: a translucent substrate; and one or more photoelectric conversion elements formed on the translucent substrate, wherein each of the photoelectric conversion elements is formed by stacking a transparent conductive film, a first charge transport layer, a power generation layer, and a second charge transport layer made of a porous film containing a carbon material, in this order from a side of the translucent substrate, and a portion of the second charge transport layer of at least one of the photoelectric conversion elements, the portion facing another transparent conductive film adjacent to the transparent conductive film of the photoelectric conversion element, is electrically connected to the other transparent conductive film via a conductive layer that is thicker than a thickness of adding up the first charge transport layer and the power generation layer so that a spacing between the transparent conductive film and the second charge transport layer is larger than a spacing between the other transparent conductive film and the second charge transport layer. 2 . The photoelectric conversion module according to claim 1 , wherein the other transparent conductive film constitutes an external extraction electrode. 3 . The photoelectric conversion module according to claim 1 , wherein the other transparent conductive film constitutes a part of the photoelectric conversion element. 4 . The photoelectric conversion module according to claim 1 , wherein the carbon material includes a carbon nanotube. 5 . The photoelectric conversion module according to claim 4 , wherein the carbon nanotube includes a single-walled carbon nanotube. 6 . The photoelectric conversion module according to claim 1 , wherein the conductive layer contains at least one of a carbon material, a metal, or a metal oxide. 7 . The photoelectric conversion module according to claim 1 , wherein the conductive layer overlaps the second charge transport layer when viewed from a direction perpendicular to the translucent substrate. 8 . The photoelectric conversion module according to claim 1 , wherein the conductive layer is formed of a conductive material and an insulating adhesive material. 9 . The photoelectric conversion module according to claim 1 , wherein the power generation layer contains a perovskite compound. 10 . A method for manufacturing a photoelectric conversion module having a translucent substrate and one or more photoelectric conversion elements formed on the translucent substrate, each of the photoelectric conversion elements being formed by stacking a transparent conductive film, a first charge transport layer, a power generation layer, and a second charge transport layer made of a porous film containing a carbon material, in this order from a side of the translucent substrate, the method comprising the step of electrically connecting a portion of the second charge transport layer of at least one of the photoelectric conversion elements, the portion facing another transparent conductive film adjacent to the transparent conductive film of the photoelectric conversion element, to the other transparent conductive film via a conductive layer that is thicker than a thickness of adding up the first charge transport layer and the power generation layer so that a spacing between the transparent conductive film and the second charge transport layer is larger than a spacing between the other transparent conductive film and the second charge transport layer.
