It is only realted to the properties of the material itself, reflectingt the pv cell optical carrier's largest compound ability; Isc is the internal short-circuit current of PV cells, light source means disposed under the standard illumination, the PV cell when the output is shorted (RL=0) of the current flowing through the output terminal (Notably, some PV cells in the literature Iph equivalent circuit model is equivalent to the Isc, which is ignored in the equivalent circuit when the output is shorted direction flows through the diode leakage current approximation); q is the electron charge, q=1.6×10-19; k is Bohr Boltzmann constant, k=1.38×10-18erg/K; T PV cell is exposed to the absolute temperature; A P-N junction PV cells inside the curve constants [4].
