Paper Abstract

Lasers have proven to be efficient tools in a variety of micro/nanoscale material processing and diagnostics. In this talk, recent research activities will be presented, focused on the laser-assisted manufacturing and diagnostics technologies for solar applications. Examples include laser scribing and spectroscopic in-situ monitoring for thin film solar cells, surface structuring to achieve improved light trapping at superior conversion efficiency, laser-assisted local doping based on wide range of laser parameters, via hole fabrications for back contact formation, and direct synthesis of multi-bandgap nanomaterials. In addition, the advanced in-situ diagnostics of laser interaction with photovoltaic materials system will be discussed.
