Layer-By-Layer Construction Strategies Towards Efficient Czts Solar Cells, Matthew J. Turnbull
Layer-By-Layer Construction Strategies Towards Efficient Czts Solar Cells, Matthew J. Turnbull
Electronic Thesis and Dissertation Repository
Solar energy has very high potential for ensuring the world’s energy requirements for the long-term future. Earth-abundant materials like Cu2ZnSnS4 (CZTS) are especially desirable, with a non-toxic, low-cost nature, though the quaternary nature allows for a lot of crystal structure variability, and thus underwhelming performance. This Ph.D. thesis is devoted to deepening the understanding of the CZTS material formation, and the processes that can be used to control it, to construct a low-cost, high efficiency CZTS-based solar cell. The layer-by-layer approach presented within this thesis shows great potential for rectifying the problem. CZTS nanocrystal (NC) stoichiometric control …
