Pani addition to improve contact between CdTe/CdS semiconductors
Júnior, Paulo Herbert França Maia; Almeida, Ana Fabíola Leite; Moreira, Raquele Lima; Teixera, Edwalder Silva; Nunes, Vanja FonteneleThis paper presents the study of the addition of the polyaniline polymer (PANI), at the junction of the cadmium telluride and cadmium sulfide (CdTe/CdS) layers in order to improve the contact between the layers, to decrease the air gap that limit the conversion photovoltaic. The morphology of CdS, CdTe and polyaniline (PANI) were characterized with multiple techniques including scanning electron microscopy (SEM...
Use of SnOx: F in the Recycling of Silicon Solar Cells
Lima, Francisco Marcone; Alves, Jean Faber Araújo; Júnior, Paulo Herbert França Maia; Martins, Felipe Mota; Teixeira, Edwalder SilvaAmongst the many parts of a silicon cells photovoltaic module, silicon is the most important and expensive constituent. Thus, research on silicon recycling from damaged cells can lead to economic and environmental benefits. In this work, the broken silicon cells were tailored to function along with the fluorine-doped tin oxide as the transparent electric conductors. The broken silicon cells were analyzed by the...
Fabricação e caracterização de células solares de CdTe/CdS com eletrólito polim...
Moreira, Raquele LimaThe current work aimed the fabrication and characterization of CdTe/CdS solar cells with polymeric electrolyte. The main component of the electrolyte was polyaniline, a conductive polymer that has been investigated as a counter electrode in dye-sensitized solar cells. The adopted deposition techniques were chemical bath and pulsed electrodeposition to obtain CdS and CdTe films which worked as the optical window...
