Abstract:
A photoelectric conversion element uses organic materials and is provided with improved quantum efficiency and response rate. The organic photoelectric conversion element includes, in a photoelectric conversion layer, p-type molecules represented by Formula (1): in which A represents any one of oxygen, sulfur or selenium, any one of R1 to R4 represents a substituted or unsubstituted aryl or heteroaryl having 4 to 30 carbon atoms, the remainder of R1 to R4 each represent hydrogen, any one of R5 to R8 represents a substituted or unsubstituted aryl or heteroaryl having 4 to 30 carbon atoms, and the remainder of R5 to R8 each represent hydrogen.
