A solid junction-type photoelectric conversion element () including a first conductive layer (), an electric power generation layer (), and a second conductive layer (), which are laminated in this order, wherein the electric power generation layer () comprises: a perovskite compound represented by a composition formula ABX, formed of an organic cation A, a metal cation B and a halide anion X, and a compound Z having no perovskite structure.

Solid junction-type photoelectric conversion element, perovskite film, and photoelectric conversion module

The present invention aims to provide a solar cell having high durability against deterioration due to moisture ingress from the side surfaces. The solar cellof the present invention includes: first and second electrodesand; a perovskite layerprovided between the first and second electrodesandand containing an organic-inorganic perovskite compound (A) represented by the formula RMXwhere R is an organic molecule, M is a metal atom, and X is a halogen atom; and a side-surface-protecting layerprovided on a peripheral side of the perovskite layerto coat at least part of a side surface of the perovskite layer, the side-surface-protecting layercontaining at least one selected from the group consisting of a metal halide (B1) and an organometal halide (B2) or containing an organohalide (C).

Solar cell and method for producing same

In a plasma film forming apparatus, two first electrodesconnected to a power sourceand two grounded second electrodesare arranged in the order of the second electrode, the first electrode, the first electrodeand the second electrode. A first flow passageformed between the central first electrodesallows a raw material gas (first gas) for being formed into a film to pass therethrough. A plasma discharge spaceof a second flow passage formed between the first and second electrodeson the both sides allows an excitable gas (second gas) to pass therethrough, which excitable gas is exited by plasma such that the raw material can be formed into a film, but that the excitable gas itself is merely excited but not formed into a film. Those gases are converged at a crossing partbetween the first and second flow passages and blown off via a common blowoff passage. By this, the apparatus composing members such as electrodes can be prevented from being adhered with a film.
