4 Conclusion
In the present investigation, process parameters for the deposition of MAPbI 3 film
were optimized utilizing parametric examination and in addition utilizing RSM. The
process parameters to be optimized were PbI 2 :CH 3 NH 3 I proportion (1:2–1:4), spin
speed (2000–3000 rpm), and annealing temperature (60–100 °C). The parametric
investigation has proposed the ideal condition as an arrangement of forerunner proportion (1:2), spin speed (2000 rpm), and annealing temperature (100 °C). After
optimizing the deposition parameters, prepared MAPbI 3 film was effectively connected in PSC manufacture and the device efficiency at this ideal condition was
7.30%. Besides, to accomplish particular ideal condition, RSM was connected to
assess the impact of deposition parameters on the device efficiency. The ideal optimum conditions recommended by RSM was the arrangement of 1:2.8 (the proportion
of PbI 2 :MAI), 2520 rpm (spinning speed) and 100 °C (annealing temperature). The
estimation of the efficiency of PSC anticipated by the model at optimum condition
was 8.52% with the desirability quality of 1.000. If there should arise an occurrence
of RSM, efficiency was improved up to 8.52% (16.7% improvement) contrasted with
7.30% utilizing parametric investigation. To check the model precision, the test was
performed at optimum condition. The exploratory estimation of PCE of PSC at optimum condition was found as 8.39%. The test esteems affirm the legitimacy of the
anticipated model.
This research did not receive any specific grant from funding agencies in the
public, commercial, or not-for-profit sectors.
