Resumo: This work focuses on a comparison between Cu2ZnSnS4 thin films with precursors grown exclusively by evaporation or by evaporation and RF Magnetron Sputtering. On the films which were grown using the second method was either sputtered ZnS or elemental Zinc. The morphology and composition of the samples was studied by SEM/EDS and their structure by XRD. Both methods were successful in producing thin films containing Cu2ZnSnS4. The samples which had their precursors grown exclusively through evaporation exhibited the most compact morphology but also were the ones that had more undesirable crystalline phases. Regarding the remaining samples, in the case where elemental Zinc was sputtered no diffusion issues were observed, whereas the ones with ZnS presented a layer of this material on the surface. This report is divided into six chapters which contain the introduction, information relative to semiconductors, Cu2ZnSnS4 solar cells, the growth and characterization techniques, the experimental procedure, results and their analysis and ends with the conclusion.

A morfologia e composição das amostras foram estudadas por SEM/EDS e a sua estrutura por DRX. Com ambos os métodos conseguiu-se crescer filmes finos de Cu2ZnSnS4. As amostras cujos precursores foram crescidos exclusivamente através de evaporação apresentavam uma morfologia mais compacta, contudo eram as que apresentavam maior número de fases cristalinas indesejadas. Relativamente às restantes amostras, no caso em que Zinco foi depositado por pulverização catódica, não foram observados problemas de difusão, contudo o mesmo não se verificou para as que continham ZnS, sendo que estas apresentavam uma camada deste material na superfície dos filmes. Este documento encontra-se dividido em seis capítulos que incluem a introdução, informação relativa a semicondutores, células solares de Cu2ZnSnS4, as técnicas de crescimento e caracterização, o procedimento experimental, os resultados e a sua análise e termina com a conclusão.Universidade de Aveiro2011-08-03T09:30:16Z2010-07-08T00:00:00Z2010-07-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/3498engMalaquias, João Corujo Brancoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:02:53Zoai:ria.ua.pt:10773/3498Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T02:41:41.737310Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
