Abstract: The present invention provides a solid junction photoelectric conversion element module including a first photoelectric conversion element, a second photoelectric conversion element, a connection portion, and a base material. The first photoelectric conversion element and the second photoelectric conversion element are disposed adjacently to each other on a surface of the base material. The first photoelectric conversion element sequentially includes a first conductive layer, a power generation layer including a perovskite layer, and a second conductive layer, and the first conductive layer of the first photoelectric conversion element is in contact with the base material. The second photoelectric conversion element sequentially includes a first conductive layer, a power generation layer including a perovskite layer, and a second conductive layer, and the first conductive layer of the second photoelectric conversion element is in contact with the base material.

Abstract: A solid junction-type photovoltaic device including: a substrate; a first conductive layer; a power generation layer including a perovskite layer; and a conductive material including a second conductive layer, which are laminated in this order, wherein the conductive material has a self-supporting property.

Abstract: A method for producing a semiconductor film, comprising spraying raw material particles to a substrate to form a semiconductor film on the substrate, wherein the raw material particles comprise semiconductor particles each having adsorbed on its surface an aggregation-suppressive substance which suppresses aggregation of the semiconductor particles.
