| Popis: | We have simulated the operation and functionality of a working Sn-based perovskite solar cell device using GPVDM and compared it against a Pb-based device. The results are extremely promising in that they showcase comparable cell efficiencies, with the Sn-based device showing a highest 21.3% efficiency (Jsc of 332.8 A/m 2 , Voc of 0.839 V, FF of 0.764) compared to 23.4% of its Pb counterpart (Jsc of 349.3 A/m 2 , Voc of 0.811 V, FF of 0.828), at similar active layer thicknesses. A deeper study of each of the Jsc, Voc and FF trends provide keen insight into charge transfer kinetics within the device, paving the way to optimal experimental setups for fabricating the most efficient non-toxic perovskite devices.
