摘要： Provided are a photoelectric conversion element that can generate power with high efficiency and has high durability, and a method for manufacturing the same.
A photoelectric conversion element according to an embodiment includes
a first electrode,
an active layer having a perovskite structure containing a halogen ion, and
a second electrode having light transmissivity,
in which a Warburg coefficient of the active layer measured by an AC impedance spectroscopy method is specified. The element can be manufactured by applying a solution containing a precursor of the perovskite structure and then performing appropriate annealing treatment or gas blowing.-

摘要： A photoelectric conversion device in an embodiment includes a first photoelectric conversion part including a first transparent electrode, a first photoelectric conversion layer, and a first counter electrode and a second photoelectric conversion part including a second transparent electrode, a second photoelectric conversion layer, and a second counter electrode, the first photoelectric conversion part and the second photoelectric conversion part being provided on a transparent substrate. The first counter electrode and the second transparent electrode are electrically connected by a connection part. As for the first photoelectric conversion layer and the second photoelectric conversion layer, adjacent portions of the adjacent first and second photoelectric conversion layers are electrically separated by an inactive region having electrical resistance higher than that of the first and second photoelectric conversion layers.

摘要： A solar panel support unit of an embodiment includes a first support member, a second support member, and a third support member. The first support member includes a first support section and a first attachment section. The first attachment section is disposed at a position spaced by a first distance from the first support section. The second support member includes a second support section and a second attachment section. The second attachment section is disposed at a position spaced by a second distance from the second support section in the panel thickness direction, the second distance being smaller than the first distance, the second attachment section having a second hole to be in communication with the first hole, the second attachment section being to overlap the first attachment section. The third support member includes a third support section and a third attachment section. The third attachment section has a third hole to be in communication with the first hole and the second hole, and is to overlap the second attachment section.

摘要： A method for manufacturing a photoelectric conversion device, that includes: forming a laminate structure of a substrate, a transparent electrode, an active layer produced by wet-coating, and a counter electrode, stacked in this order; and thereafter forming a cavity by: (a) pressing an adhesive material just against a defect formed on the surface of said counter electrode, and then peeling off said adhesive material together with said defect and the peripheral part thereof; or (b) sucking a defect formed on the surface of said counter electrode, so as to remove said defect and the peripheral part thereof, where said cavity penetrates through the counter electrode and unreached to the transparent electrode.

摘要： The present embodiments provide a photoelectric conversion device having a laminate structure of a substrate, a transparent electrode, an active layer, and a counter electrode, stacked in this order. In the device, a cavity is provided on the counter electrode-side. The cavity penetrates through the counter electrode and has an opening area larger in the counter electrode than in the active layer.
