ABSTRACT:
Provided is a process for preparing an absorption layer of a solar cell composed of a 1B-3A-Se compound, comprising applying a metal selenide nanoparticle as a precursor material to a base material and subjecting the applied nanoparticle to thermal processing, whereby the crystal size of the 1B-3A-Se compound can be increased as compared to a conventional method using a metal in the form of an oxide as a precursor material, consequently resulting in an enhanced efficiency of the solar cell, and the manufacturing process can be simplified with omission of hydrogen reduction and selenidation processes.
