The photoelectric device includes: a semiconductor substrate that is formed of monocrystalline silicon and has first and second surfaces that are opposite to each other; a doping unit formed in the first surface of the semiconductor substrate; and an insulating layer that is formed between the doping unit and the second surface of the semiconductor substrate, wherein the doping unit includes: a first semiconductor layer including a first dopant doped in the monocrystalline silicon; and a second semiconductor layer including a second dopant doped in the monocrystalline silicon.

Description

[0001] This application claims U.S. Provisional Application No. 61 / 725,437, filed in the U.S. Patent and Trademark Office on November 12, 2012, and U.S. Patent Application No. 13 / 949,147, filed in the U.S. Patent and Trademark Office on July 23, 2013 The priority and benefits of these applications are hereby incorporated by reference in their entirety. technical field [0002] One or more embodiments of the present invention relate to an optoelectronic device and a method of manufacturing the optoelectronic device. Background technique [0003] Currently, development of clean energy is being promoted due to problems such as energy depletion of the earth and environmental pollution. Photovoltaic energy generated using solar cells is directly converted from sunlight, and thus is considered a new clean energy source. [0004] However, the cost of generating photovoltaic energy (currently industrially generated by using solar cells) is high compared with the generation of therm...
