Abstract
The cost of modern high efficiency wafer-based solar cells is driven in part by poor materials utilization of the absorber materials. Solar cells made from thin film absorbers attached to inexpensive support substrates potentially offer reduced materials costs compared to wafer-based devices; however, conventional processes for producing thin film absorber layers on amorphous or polycrystalline substrates result in amorphous or polycrystalline films, which, due to a high degree of crystalline imperfection, suffer from reduced carrier lifetime due to Shockley-Read-Hall recombination. Here, I present work I have done on ion-beam-assisted deposition, environmentally-assisted cracking induced epitaxial liftoff, and laser liftoff of epitaxial GaAs thin films, as potential pathways for the scalable production of absorber materials for lower cost, high efficiency thin film solar cells. Additionally, I discuss multiple concepts in X-ray diffraction and Reflected High Energy Electron Diffraction that are used extensively throughout this work to investigate the atomic structure of thin films.
