Abstract
Provided are a solar cell and a method of manufacturing the same. The method of manufacturing the solar cell includes stacking a solar cell device layer containing GaN on a sacrificial substrate, etching the solar cell device layer to expose the sacrificial substrate, thereby forming one or more solar cell devices comprising the solar cell device layer, anisotropically etching the exposed sacrificial substrate, contacting the solar cell devices to a stamping processor to remove the solar cell devices from the sacrificial substrate, and transferring the solar cell devices onto a receiving substrate. A high temperature semiconductor process may be performed on a substrate such as a silicon substrate to transfer the solar cell devices onto the substrate, thereby manufacturing flexible solar cells. Also, a large number of solar cells may be excellently aligned on a large area. In addition, economical solar cells may be manufactured.
