This model contains five parameters, that is, the photocurrent ( $$ {I}_ {ph} $$ ), saturation current ( $$ {I}_o $$ ), series resistance ( $$ {R}_s $$ ), shunt resistance ( $$ {R}_ {sh} $$ ), and the modified diode factor ( $$ a $$ ).

The use of equivalent electric circuits makes it possible to model characteristics of a PV cell. The method used here is implemented in MATLAB programs for simulations. The same modeling technique is also applicable for modeling a PV module. There are two key parameters frequently used to characterize a PV cell.

A simple equivalent circuit model for a PV cell consists of a real diode in parallel with an ideal current source. When the leads of the equivalent circuit for the PV cell are shorted together, no current flows in the (real) diode since Vd= 0, so the whole current from the ideal source flows through the shorted leads.

“Using 1,3-propane diammonium (PDA), QFLS increases by 90 meV,” the scientists explained. The cell achieved a power conversion efficiency of 26.3% and an open-circuit voltage of 2.13 eV, as certified by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
