Abstract: PROBLEM TO BE SOLVED: To provide a wavelength conversion film which has an up-conversion function with excellent conversion efficiency, and a photoelectric conversion device.SOLUTION: In the wavelength conversion film, first quantum dots and second quantum dots inside a matrix layer are such that a first normal energy level excited by multiplex light irradiated on the first quantum dots is larger than a second normal energy level excited by multiplex light irradiated on the second quantum dots. The matrix layer is composed of a dielectric or an organic material whose band gap is larger than the first normal energy level. When the first and second quantum dots are joined together, their energy band structure constitutes type II, where the matrix layer around each quantum dot forms a selective tunnel barrier and also forms a mini-band whose energy transition probability at an energy level higher than an energy level difference at which a stimulable light-emitting material in the matrix layer makes a luminescent transition becomes heightened, thereby causing the stimulable light-emitting material to make an energy transition for up-conversion.
