Organic photoelectric device comprises a first electrode, a first carrier transfer layer, an active layer, a second carrier transfer layer and a second electrode. The first electrode is a transparent electrode. The active layer includes at least one organic semiconductor material including a structure such as Formula I: n n n n n n n n n n The second carrier transfer layer is composed between the active layer and the second electrode. When X1 and X2 are selected from one of Si, Ge and derivatives thereof, the active layer further includes an organic solvent, and the solubility of the organic solvent to the active layer is not less than 5 mg/mL. When X1 and X2 are selected from one of C and its derivatives, the active layer further includes an additive. The power conversion efficiency of the organic photoelectric device of the present invention can be up to more than 14%. |
