Abstract
Provided is a solar cell having a spherical surface. The solar cell includes a substrate having a back contact layer formed thereon; a plurality of carbon nanoelectrodes formed on the back contact layer so as to cross the back contact layer at right angles; a p-type junction layer formed to have a plurality of spheres which surround the plurality of carbon nanoelectrodes; an n-type junction layer and a transparent electrode layer that are sequentially laminated on the p-type junction layer; a first electrode formed on one side of the top surface of the back contact layer; and a second electrode formed on one side of the top surface of the transparent layer.

A solar cell having a spherical surface comprising:
- a substrate having a back contact layer formed thereon;
- a plurality of carbon nanoelectrodes formed on the back contact layer so as to cross the back contact layer at right angles;
- a p-type junction layer formed to have a plurality of spheres which surround the plurality of carbon nanoelectrodes;
- an n-type junction layer and a transparent electrode layer that are sequentially laminated on the p-type junction layer;
- a first electrode formed on one side of the top surface of the back contact layer;
- and
- a second electrode formed on one side of the top surface of the transparent layer.
A method of manufacturing a solar cell having a spherical surface, comprising the steps of:
- forming a back contact layer on a substrate;
- forming a plurality of transition metals on the back contact layer;
- growing the plurality of transition metals into a plurality of carbon nanoelectrodes which are perpendicular to the back contact layer;
- performing an inkjet printing process on the plurality of carbon nanoelectrodes so as to form a p-type junction layer having a plurality of spheres which surround the carbon nanoelectrodes;
- sequentially forming an n-type junction layer and a transparent electrode layer on the p-type junction layer;
- forming a first electrode on one side of the top surface of the back contact layer;
- and
- forming a second electrode on one side of the top surface of the transparent electrode layer.
