摘要

NiOX has proven to be a highly stable and effective inorganic hole transport layer (HTL) in inverted perovskite solar cells (PSCs). However, its complexity during the synthesis process and poor electrical properties impede the improvement of efficient PSCs. This study introduces Ag2+ as an efficient dopant to boost up the NiOX thin film properties through an eco-friendly green synthesis approach utilizing aloe vera leaves extract as a stabilizing or complexing agent. The research also examines the effect of different doping concentrations of Ag2+ (0 wt%, 7 wt%, 10 wt%, and 12 wt%) on film properties. Structural analysis indicates improved crystallinity in Ag: NiOx thin films compared to the undoped ones. Smoother films are observed for Ag-doped NiOx thin films; however, the thin film exhibits agglomeration at higher Ag doping concentrations (12 wt%). The addition of Ag dopants increases Eg value from 3.81 eV (undoped NiOX) to 3.85 eV (Ag: NiOX), while the transmittance spectra demonstrated nearly identical behaviour. Electrical properties indicate that the highest mobility and the lowest resistivity are observed for the 10 wt% Ag: NiOx thin film, with values of 81.3 cm²/Vs and 2.41 × 102 Ω·cm, respectively. For verifying the usability of deposited Ag: NiOx films as the HTL in p-i-n PSC a simulation study has been conducted and it is observed that, although the PCE, JSC, VOC are lower for the 10 wt% Ag-doped NiOx as the HTL in PSCs compared to undoped one, the FF (74%) is improved, resulting in a well-structured J-V curve.
