Nanostructured titanium dioxide average size from alternative analysis of Scher...
Lima,Francisco Marcone; Martins,Felipe Mota; Maia Júnior,Paulo Herbert França; Almeida,Ana Fabíola Leite; Freire,Francisco Nivaldo AguiarABSTRACT The materials sizing in nano-scale is a challenge to be overcome, because the size determined by various methods differ. In order to shed light about the nanomaterials sizing, a modified Scherrer's equation was applied to estimate more accurately the nanostructured titanium dioxide crystal size. The manufactured titanium dioxide-nanostructured powder with nominal average size about 21nm was used as the...
Use of SnOx:F in the Recycling of Silicon Solar Cells
Lima,Francisco Marcone; Alves,Jean Faber Araújo; Maia Júnior,Paulo Herbert França; 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...
