Paper Abstract

A method of non-vacuum synthesis of CuInSe2 (CIS) thin films is presented. The method is based on electrophoretic deposition (EPD) of Cu-In composite nanoparticles in liquid solvents. Colloidal suspensions of Cu-In composite nanoparticles are prepared with pulsed laser ablation without additional stabilizing agents. The charge acquisition of the nanoparticles in solvents, deposition of particles on electrode surfaces will be explained. After selenization in selenium vapor in atmospheric pressure, polycrystalline CIS films and solar cell devices are produced. We will demonstrate EPD as a new choice of low-cost synthesis of thin film solar absorbers.
