The great power conversion efficiency of organic HTM based lead-free PSC brings up the new possibilities for obtaining renewable energy.īag, A., Radhakrishnan, R., Nekovei, R., Jeyakumar, R.: Effect of absorber layer, hole transport layer thicknesses, and its doping density on the performance of perovskite solar cells by device simulation. For low recombination and a high fill factor, an HTM (Spiro-OMeTAD) of 1–100 nm is necessary. Again a very thin or thick HTL is not ideal for high PCE. Device efficiency is improved by increasing the doping density up to 10 18 cm −3 in the perovskite layer due to built-in electric field across the solar cell. Although more carriers are created in the cell due to increased absorption, decreased collection efficiency is related to recombination, which decreases V oc for thick perovskite layers. Our findings reveal that using a thin absorber layer results in low photo generated charge carriers due to less absorption, but high carrier extraction. Finally, in order to improve the device's performance, an anode material with high work function is required. Furthermore, by adjusting the HTM thickness and the defect density of HTM and absorber layer, promising findings 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. According to this study, an perovskite layer thickness of 1000 nm is suitable for a decent photovoltaic cell. 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. The results show that utilizing CuO as an HTM produces better outcomes than other HTMs, with an efficiency of 28.45%.
Spiro-OMeTAD, PEDOT:PSS, CuO and Cu 2O are the HTM materials used. The cell structure used in this study is FTO/TiO 2/CH 3NH 3SnI 3/HTM (variable)/Au(variable).
This research looks at two organic and two inorganic HTM layers.
