Abstract:Open circuit voltage is an essential factor to judge the performance of the photovoltaic cells. Basically, the photo-electrochemical (PEC) measurement shows the solid/electrolyte chemical interaction under light illumination. The PEC measurement reflects the electrical and optical properties of the semiconductors. The optical sensitivity of a semiconductor is used to derive an equation. In the present study, we introduced an equation to estimate the open circuit voltage of a pn junction from the PEC measuremen… Show more
This paper suggests that the cell voltage and reaction energy can be estimated using the difference between Fermi energies of the products and reactants. DFT calculations for important Li-ion cathodes’...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
