On the other hand, the operating mechanics of silicon solar cells, DSCs, and perovskite solar cells differ. The performance of silicon solar cells is described using the dopant density and distribution, which is modelled as a p-n junction with doping. The redox level in electrolytes impacts the output voltage of a device in DSCs.
Each component layer of the perovskite solar cell, including their energy level, cathode and anode work function, defect density, doping density, etc., affects the device's optoelectronic properties. For the numerical modelling of perovskite solar cells, we used SETFOS-Fluxim, a commercially available piece of software.
