What is maximum power transfer in a solar cell?
The current study is based on the concept of maximum power transfer. Equal system impedance and load impedance achieve maximum power transfer, acquiring the highest utilization efficiency of a solar cell.

How does series resistance affect f-PSCs?
Series resistance (R s) mainly depends on the front and back surface contact resistance of f-PSCs [, , , ]. When increases R s then the carrier density decreases as a result current decreases in the cells.
What causes shunt resistance in a solar cell?
Shunt resistance (R s h) is created due to leakage currents produced at the edge of the f-PSCs and the imperfection of the cell structure . This affects the parallel conductivity of a solar cell depending on the cell junction [, , , ]. As leakage currents increase, the efficiency of any solar cell decreases.
