摘要
The present invention provides: a layered perovskite that has a high band gap energy and an excellent carrier transport capacity; a light absorption layer containing the layered perovskite; a light-absorption-layer-equipped substrate and a photoelectric conversion element that have the light absorption layer; and a solar cell having the photoelectric conversion element. In the layered perovskite according to present invention, the inter-surface distance of (002) planes calculated from an X-ray diffraction peak obtained by an out-of-plane method is 2.6 to 5.0 nm, and, in the X-ray diffraction peak, an intensity ratio ((111) plane/(002) plane) of an X-ray diffraction peak intensity at a (111) plane with respect to an X-ray diffraction peak intensity at the (002) plane is 0.03 or more.
