“…As a result, for high charge carrier mobility, diffusion length increases, and recombination of charge carriers reduces. There could be different causes for the greater J sc when compared to recently published data [49,50]. The performance of the reported PSC is promising and reliable with the Sn-based PSC [27,29].…”

“…The high value of J sc was reached because current density is linearly related to charge carrier mobility. Devi et al [49] and Khattak et al [50], on the other hand, used substantially lesser and identical values of µ e (1.6 cm 2 /Vs) and µ h (0.16 cm 2 /Vs) and reported good J sc ( 30 mA/cm 2 ) results. Again we found in some previous experimental literature that diffusion length is directly proportional to the mobility's square root [51].…”

The Scaps-1d simulator was used to simulate a lead-free perovskite CH 3 NH 3 SnI 3 based solar cell devices fabricated from different hole transport materials (HTM). This research looks at two organic and two inorganic HTM layers. The cell structure used in this study is FTO/TiO 2 / CH 3 NH 3 SnI 3 /HTM(variable)/Au(variable). Spiro-OMeTAD, PEDOT:PSS, CuO and Cu 2 O are the HTM materials used. The results show that utilizing CuO as an HTM produces better outcomes than other HTMs, with an e ciency of 28.45%. The thickness, acceptor concentration (N A ), and defect density (N t ) of the perovskite layer on optoelectronic properties of the solar cell are focus of simulation studies. According to this study, an perovskite layer thickness of 1000 nm is suitable for a decent photovoltaic cell. Furthermore, by adjusting the HTM thickness and the defect density of HTM and absorber layer, promising ndings of J sc of 34.38 mAcm − 2 , V oc of 1.011 V, FF of 80.85% and PCE of 28.10% were obtained for Spiro-OMeTAD based PSC. Finally, in order to improve the device's performance, an anode material with high work function is required. Our ndings reveal that using a thin absorber layer results in low photo generated charge carriers due to less absorption, but high carrier extraction. Although more carriers are created in the cell due to increased absorption, decreased collection e ciency is related to recombination, which decreases V oc for thick perovskite layers. Device e ciency is improved by increasing the doping density up to 10 18 cm − 3 in the perovskite layer due to built-in electric eld across the solar cell. Again a very thin or thick HTL is not ideal for high PCE. For low recombination and a high ll factor, an HTM (Spiro-OMeTAD) of 1-100 nm is necessary. The great power conversion e ciency of organic HTM based lead-free PSC brings up the new possibilities for obtaining renewable energy.

In this paper, a n-i-p planar heterojunction simulation of Sn-based iodide perovskite solar cell (PSC) is proposed. The solar cell structure consists of a Fluorine-doped tin oxide (FTO) substrate on which titanium oxide (TiO2) is placed; this material will act as an electron transporting layer (ETL); then, we have the tin perovskite CH3NH3SnI3 (MASnI3) which is the absorber layer and next a copper zinc and tin sulfide (CZTS) that will have the function of a hole transporting layer (HTL). This material is used due to its simple synthesis process and band tuning, in addition to presenting good electrical properties and stability; it is also a low-cost and non-toxic inorganic material. Finally, gold (Au) is placed as a back contact. The lead-free perovskite solar cell was simulated using a Solar Cell Capacitance Simulator (SCAPS-1D). The simulations were performed under AM 1.5G light illumination and focused on getting the best efficiency of the solar cell proposed. The thickness of MASnI3 and CZTS, band gap of CZTS, operating temperature in the range between 250 K and 350 K, acceptor concentration and defect density of absorber layer were the parameters optimized in the solar cell device. The simulation results indicate that absorber thicknesses of 500 nm and 300 nm for CZTS are appropriate for the solar cell. Further, when optimum values of the acceptor density (NA) and defect density (Nt), 1016 cm−3 and 1014 cm−3, respectively, were used, the best electrical values were obtained: Jsc of 31.66 mA/cm2, Voc of 0.96 V, FF of 67% and PCE of 20.28%. Due to the enhanced performance parameters, the structure of the device could be used in applications for a solar energy harvesting system.
