Influence of Temperature on Electron Transport, Current-Voltage Characteristics, and Capacitive Properties of MIM Nanostructures with Amorphous Niobium Pentoxide

Applied Nano
Currently, titanium dioxide films are widely used as the electron transport layer material in perovskite solar cells. An alternative to titanium dioxide for this role could be niobium pentoxide (Nb2O5), an n-type conducting semiconductor oxide.
