| Résumé : |
The promising technology of CH3NH3PbI3 perovskite solar cells is particularly interested in increasing efficiency. Solar cells based on perovskite represent an innovative approach to achieve the best possible photovoltaic performances. The main objective of this work is to study the performance of CH3NH3PbI3 perovskite-based solar cells, using the SILVACO software. In this work, we examined the electrical characteristics (I-V) of the primary modelled solar cell, and The electrical outputs of the primary PSC solar cell obtained are the short-circuit current density Jsc, the open-circuit voltage Voc, the fill factor FF and the conversion efficiency η are 21.33 mA/cm2, 0.88 V, 0.72 and 14.44 %, respectively, agree with experimental data. On the other hand, the simulation enabled us to study the effect of the ETM region thickness, the effect of HTM region thickness and the last effect which is the replacing of the HTM region (Spiro-OMeTAD) with PEDOT: PSS on the electrical characteristics of the perovskite solar cell. Through the obtained results we noticed that the PEDOT: PSS material improved the characteristics (I-V) of the perovskite solar cell and the optimum parameters of the thickness of ETL and HTL layers which are 0.1 µm, in the two cases. the obtained output parameters of the solar cell improved in the case of the optimum thickness of ETL are Jsc= 27.91 mA/cm2, Voc= 0.88 V, FF= 0.72 and η= 17.71% While in the case of the optimum thickness of HTL are Jsc= 27.2 mA/cm2, Voc= 0.88 V, FF= 0.72 and η= 17.61%. |
