SOLAR CELL HAVING A DOUBLE-SIDED STRUCTURE, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a solar cell having nanostructures on both surfaces of a transparent substrate, and to a method for manufacturing same. The nanostructures, which face each other with respect to the substrate and which transport electrons, are formed using zinc-oxide nanowires. Also, a hole-transport layer using CIS nanoparticles is formed in order to absorb light having a short wavelength and to transport generated holes. A hole-transport layer including CIGS nanoparticles for absorbing light having a relatively long wavelength is formed on the side facing the hole-transport layer including the CIS nanoparticles.
