Question

equation for voltage interms of E when a cell is in a open circuit​

Answer 1

Answer:

Explanation:

As we know, the open circuit voltage equals to the quasi-Fermi level separation of a solar cell under illumination. Common way to calculate the voltage is using the equation, KT/q*ln(Iph/I0+1). Another method I found from a paper is by integration of extra electric field caused by extra photo carriers generated in the solar cell (Poisson equation).
