1. A photoelectric device for converting optical energy into electrical energy, the photoelectric device comprising:
a photoactive layer comprising:
a quantum dot layer configured to generate an electric charge in response to light incident thereon, and
a semiconductor layer configured to conduct the electric charge generated by the quantum dot layer;
a first electrode electrically connected to a first end of the semiconductor layer; and
a second electrode electrically connected to a second end of the semiconductor layer,
wherein the semiconductor layer comprises a lower semiconductor layer and an upper semiconductor layer, and the quantum dot layer is disposed between the lower semiconductor layer and the upper semiconductor layer, and
wherein a thickness of the lower semiconductor layer is different from a thickness of the upper semiconductor layer.
