Abstract This paper investigates the effect of incorporating a single-walled carbon nanotubes (SWCNTs) layer into perovskite solar cell (PSC) structure as an effective technique to boost energy harvesting. The proposed PSC utilizes SWCNTs underneath CH 3 NH PbI absorbing forming novel design (ITO/SnO 2 /CH /SWCNTs/NiO x /C) half tandem structure. suggested is numerically analyzed using finite element method (FEM). effects varying thickness and doping concentration added material rear electrode are investigated maximize power conversion efficiency (PCE) PSC. Results 3D opto-electrical study bandgap analysis confirm that utilizing 680 nm with 1.1 × 10 20 cm -3 beneath 150 enhances PCE short circuit current density (J SC ) $$25.6\%$$ 25.6 % $$31.201 mA/{cm}^{2}$$ 31.201 m A / cm 2 , respectively due improving absorption by $$27.65\%$$ 27.65 . Higher performance has been achieved gold (Au) instead (C) one, causing total enhancement J $$6.185\%$$ 6.185 $$9.18\;mA/cm^{2}$$ 9.18 c over their values for /P3HT/NiO reported in previously published literature. can be considered efficient alternative conventional owing its higher reduced toxicity.
