Tutors: Sònia Estradé Albiol, Víctor Izquierdo Roca and Javier Blanco PortalsIn the present work, we study a kesterite Cu2ZnSnSe4 solar cell at the nanoscale level in order to analyze the defects that lower its energy conversion efficiency. First of all, current density{voltage characteristics, quan- tum effciency, photoluminiscence, and Raman spectroscopy are studied to obtain macroscopic and microscopic information about the device. Then, High Resolution Transmission Electron Microscopy (HRTEM) is performed to observe the cross-section and, for the first time, the front interface of the absorber with nanoscopic detail9 p.application/pdfengcc-by-nc-nd (c) Fonoll, 2018http://creativecommons.org/licenses/by-nc-nd/3.0/es/Compostos de sofreMicroscòpia electrònica de transmissióCèl·lules solarsTreballs de fi de màsterSulfur compoundsTransmission electron microscopySolar cellsMaster's thesesinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
