Estimation of the Open Circuit Voltage of a pn Junction Based on Photoelectrochemical Measurements

Abstract

Open circuit voltage is an essential factor to judge the performance of the photovoltaic solar 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. In the present study, we introduced an equation to estimate the open circuit voltage of the pn junction from the PEC measurements of the individual layer.
