Claim 0:
1. A photoelectric conversion element, comprising an anode, a cathode, an active layer provided between the anode and the cathode, and a hole transport layer provided between the anode and the active layer, wherein the active layer includes a p-type semiconductor material, which is a polymer compound having an absorption peak wavelength of 900 nm or higher, and an n-type semiconductor material, and an energy gap between an Lowest Unoccupied Molecular Orbital (LUMO) of the n-type semiconductor material contained in the active layer and a Highest Occupied Molecular Orbital (HOMO) of a hole transport material contained in the hole transport layer is less than 0.9 eV, wherein the photoelectric conversion element has a signal-to-noise ratio of 1.4×103 or greater.
