Temperature influences of the interfacial layer in MOS (Pt/TiO2/Si) structures

open access: yesКонденсированные среды и межфазные границы, 2023
In this paper present I-V and C-V electrical characteristics of MOS (Pt/TiO2/Si) were reported. In the I-V characteristics the various electric parameter estimated such as the ideality factor (n), barrier height (FB), leakage current (Ic) and saturation

Anomalous dark current ideality factor (n > 2) in thin-film solar cells: The role of grain-boundary defects

open access: yes, 2014
By comparing simulated and measured dark I-V characteristics of CIGS cells, we investigate the low-voltage anomalous (> 2) ideality factor, and find that it can be explained by large donor trap concentrations at grain boundaries, and SRH recombination ...

On the Differences between Dark and Light Ideality Factor in Polymer:Fullerene Solar Cells

open access: yes, 2015
Ideality factors are derived from either the slope of the dark current/voltage curve or the light intensity dependence of the open-circuit voltage in solar cells and are often a valuable method to characterize the type of recombination.
