Abstract

Chemical bath deposition (CBD) process conditions for depositing CdS buffer layers was studied for high efficiencies of CIGS thin film solar cells. Growth rate of CdS thin films has an effect on surface morphology and quality of thin films. By the change of growth rate, CdS buffer layers showed a large difference in surface morphology and this difference was closely related with the photovoltaic properties of CIGS solar cells.
