Abstract
Official abstract text for this publication.
The present disclosure is to provide a multi-junction light energy conversion element including a material having a band gap suitable for a light energy conversion layer located upstream in an incidence direction of light. The present disclosure provides a light energy conversion element, comprising a first light energy conversion layer containing SrZn2N2 and a second light energy conversion layer containing an light energy conversion material. The light energy conversion material has a narrower band gap than the SrZn2N2.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light energy conversion device, comprising: a light energy conversion element; a first electrode; and a second electrode, wherein the light energy conversion element, consisting of: a first light energy conversion layer as a single layer containing SrZn 2 N 2 ; and a second light energy conversion layer containing an light energy conversion material, wherein the light energy conversion material has a narrower band gap than the SrZn 2 N 2 , the first light energy conversion layer of the light energy conversion element is present between the second light energy conversion layer of the light energy conversion element and the second electrode, the second light energy conversion layer of the light energy conversion element is present between the first light energy conversion layer of the light energy conversion element and the first electrode, and the second electrode is an electric conductor having a transparency such that light travels through the second electrode. 2. A light energy conversion device, comprising: a light energy conversion element; a first electrode; and a second electrode, wherein the light energy conversion element, consisting of: a first light energy conversion layer as a single layer containing SrZn 2 N 2 ; a second light energy conversion layer containing an light energy conversion material; and a joint layer provided between the first light energy conversion layer and the second light energy conversion layer, wherein the light energy conversion material has a narrower band gap than the SrZn 2 N 2 , the first light energy conversion layer of the light energy conversion element is present between the second light energy conversion layer of the light energy conversion element and the second electrode, the second light energy conversion layer of the light energy conversion element is present between the first light energy conversion layer of the light energy conversion element and the first electrode, and the second electrode is an electric conductor having a transparency such that light travels through the second electrode. 3. The device according to claim 1 , wherein the second electrode is located upstream of the light energy conversion element in an incidence direction of the light. 4. The device according to claim 1 , wherein the light is sunlight. 5. The light energy conversion element according to claim 1 , wherein the second light energy conversion layer of the light energy conversion element is a single layer.
