To reach large applications, obstructions as high silicon prices must be overcome. Solar concentration systems are a potential solution since silicon is replaced by cheaper material (like mirrors or lenses). Nevertheless, there are still many issues and challenges yet to overcome. One of these challenges is the economic cost of the solar cells, since the CPV systems need to integrate expensive high efficiency solar cells specially designed to operate at high levels of radiation. Thus, it is necessary to explore new approaches. In this thesis presents a study of the potential of the screen-printed silicon solar cells to integrate the CPV systems, concretely the HSUN system. Two solar cells, conventional 1Sun and conventional 15Suns, were analyzed and integrated in the HSUN sub-receivers, in order to understand their behavior under several levels of concentration and when integrated in series in sub-receivers. After the first part of the experimental campaign (electrical characterization of solar cells) it was concluded that the conventional standard silicon solar cells are unsustainable for use in the HSUN system (which operates a 15 suns), since these solar cells only work properly up to a concentration of 5 suns. Regarding the Upgraded 1-sun silicon solar cells, the results were satisfactory regarding their behavior under concentration, until a concentration level of 20 suns. In the second part of the experimental campaign, the Upgraded 1-sun solar cells were integrated in the HSUN sub-receivers and their behavior was analyzed. The results taking from this part of the experimental campaign prove the good performance of the Upgraded solar cells and that their performance is unaffected by their integration in the sub-receivers. Associated to this part of the experiments, was also performed the optimization of the mounting process of the sub-receivers. This optimization provided a faster process with a lower probability of damaging the solar cells. To a complete study of the potential of these solar cells, it is important to take into account the economic viability of the solar cells. Comparing the cost-efficiency of the standard conventional solar cells, the LGBC solar cells (cells used actually in the HSUN system) and the Upgraded 1-sun solar cells, it was concluded that the solar cells more viable up to a concentration level of 24 suns are the Upgraded 1-sun solar cells, being that from this concentration level the LGBC solar cells solar cells present themselves as the most viable. Therefore, and taking into account all the work developed along this thesis, it was concluded that the most cost-efficient solar cells to integrate the HSUN system are the conventional solar cells with some characteristics optimized for the required concentration levels.Faculdade de Ciências e TecnologiaValtchev, StanimirPina, LuísRUNRamos, Carina Alexandra Rebelo2014-01-17T11:29:17Z20112011-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/11020enginfo: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:RCAAP2024-03-11T03:45:16Zoai:run.unl.pt:10362/11020Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:19:58.466401Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
