Document Type and Number:
Japanese Patent JP7284128
Kind Code:
B2
Abstract:
Heat resistance is improved.A photoelectric conversion element 10 includes an anode 12, a cathode 16, and an active layer 14 provided between the anode and the cathode, in which the active layer contains at least one p-type semiconductor material and at least two n-type semiconductor materials, and a dispersive energy Hansen solubility parameter δD(P) of the at least one p-type semiconductor material and a first dispersive energy Hansen solubility parameter δD(Ni) and a second dispersive energy Hansen solubility parameter δD(Nii) of the at least two n-type semiconductor materials satisfy the following requirements (i) and (ii):2.1 MPa0.5<|δD(P)−δD(Ni)|+|δD(Ni)−δD(Nii)|<4.0 MPa0.5 Requirement (i):0.8 MPa0.5<|δD(P)−δD(Ni)| and 0.2 MPa0.5<|δD(Ni)−δD(Nii)| Requirement (ii):
