Contribution of doping concentration of the Perovskite layer to the optimization of solar cell efficiency

This study tries to observe the Perovskite PV cell efficiency taking consideration of doping density. The Perovskite layer ($\mathbf{P}$-layer) is a very significant layer for the optimization of the PV cell efficiency. From analysis of simulation, it is seen that the energy transformation efficiency is highly affected by the doping density of the P-layer. The maximum efficiency that has been obtained is 36.82% for the acceptor density of $1.0 \times 10^{27} / \mathrm{cm}^{3}$. And, the fill factor obtained for this doping concentration is 91.30%. Voc, MPP voltage are also recorded highest for this doping density, though the Isc density and MPP current have been declined to a low key extent of order.
