Production of thin film solar cells is growing at over 40% per year. However, advances are limited by a lack of fundamental understanding of the materials. This talk reviews our studies of the growth mechanisms, optoelectronic properties and surface science of one class of materials applied to these cells: Cu(In,Ga)Se2. The work focuses on epitaxial single crystals grown with a variety of orientations to provide controlled surfaces for study. Scanning probe measurements show how surface morphology, atomic dynamics, and surface energy are connected.
