Solar cell using p-i-n nanowire

摘要

A solar cell using a p-i-n nanowire that may generate light by absorbing solar light in a wide wavelength region efficiently without generating light loss and may be manufactured with a simplified process and low cost. The solar cell includes: a semiconductor layer formed of a semiconductor material; and a photoelectromotive layer including a semiconductor structure including a core-nanowire that extends long in an upward direction of the semiconductor layer and is formed of an intrinsic semiconductor material, and a shell-nanowire that is formed to surround a periphery of the core-nanowire and is formed of a semiconductor material, wherein the semiconductor material that is used for forming the semiconductor layer includes an n-type semiconductor material, or the semiconductor material that is used for forming the shell-nanowire includes a p-type semiconductor material, and the semiconductor material that is used for forming the semiconductor layer includes a p-type semiconductor material, and the semiconductor material that is used for forming the shell-nanowire includes an n-type semiconductor material.
