Doctoral dissertation, Harvard University.http://dissertations.umi.com/gsas.harvard:11685http://nrs.harvard.edu/urn-3:HUL.InstRepos:12274579This dissertation explores strategies for improving photolvoltaic efficiency and reducing cost using femtosecond-laser processing methods including surface texturing and hyperdoping. Our investigations focus on two aspects: 1) texturing the silicon surface to create efficient light-trapping for thin silicon solar cells, and 2) understanding the mechanism of hyperdoping to control the doping profiles for fabricating efficient intermediate band materials.en-USEnergyOpticsEngineeringhyperdopinglaserlight trappingmechanismphotovoltaicstexturingThesis or Dissertation2016-06-04
