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. | 17

Since the 1970s light has been used to trap, control and manipulate particles on the micro and nanoscales. In particular optical tweezer traps have been used in applications in biology, chemistry, engineering and physics. Given the current emphasis on nanotechnology, applications continue to arise where nano and sub nano-precision are desired. The ability to use optical tweezers to confine smaller particles and manipulate these particles with greater precision is of interest. | 19
