  • Efficiency enhancement and doping type inversion in Cu2CdSnS4 solar cells by Ag substitution 

    Ibrahim, Ahmad; Lie, Stener; Tan, Joel Ming Riu; Swope, Ryan; Gon Medaille, Axel; Hadke, Shreyash; Saucedo Silva, Edgardo Ademar; Agrawal, Rakesh; Wong, Lydia H. (Royal Society of Chemistry (RSC), 2023-12-22)
    Article
    Open Access
    The main limiting factor of kesterite-related solar cells is the low open-circuit voltage (VOC) relative to their bandgap. This drawback has been correlated with the easily formed anti-site defects caused by similar ionic ...
  • Electrical impedance tomography to measure spirometry parameters in chronic obstructive pulmonary disease patients 

    Vargas Luna, José Miguel; Kashina, Svetlana; Riu Costa, Pere Joan; Casan Clará, Pere; Balleza Ordaz, José Marco (Sociedad Mexicana de Ingeniería Biomedíca, 2022-12-01)
    Article
