Document Type and Number:
Japanese Patent JP2021027078
Kind Code:
A
Abstract:
To provide a photoelectric conversion element that can prevent a reduction in output in low-intensity light after high-temperature storage.SOLUTION: A photoelectric conversion element 101 has a first electrode 2 on a first substrate 1, has an electron transport layer 4 on the first electrode 2, has a photosensitization compound 5 on a surface of an electron transport material that form the electron transport layer 4, and has a hole transport layer 6 in an upper part and inside of the electron transport layer 4. The hole transport layer 6 contains a specific cyclic alkali metal salt compound having a large molecular size and a specific basic compound having a low fluidity even under a high temperature environment.SELECTED DRAWING: Figure 1
