Abstract: 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.
