Determination of the peak power voltage using explicit PLM of an illuminated solar cell

A simple power law model (PLM) of J-V equation to characterize an illuminated solar cell can be represented as j = 1 - (1 - γ)ν - γν^m where the normalized voltage, v and normalized current density j can be represented as ν=V/V_oc and j=J/J_sc and γ and m are parameters related to the physical parameters of the solar cell. Using this model, the empirical equation for the peak power voltage works only for good quality solar cells. Here in this paper, a semi-empirical approach is considered to determine the peak power voltage for any illuminated solar cell.
