Study of gold, silver-gold nanoparticles incorporated to carbon paint for electrodes application in thin-film solar cells

Year: 2025

Type: article

Abstract: The study investigated Au-Ag and Au nanoparticles (NPs) synthesized chemically and added to a commercial conductive carbon paint used as electrodes in Bi₂S₃/PbS thin-film solar cells. I-V measurements were used for device characterization. NPs were found on the carbon paint surface with sizes of 15.2 ± 0.2 nm (Au-Ag(1)), 29 ± 7.5 nm (Au-Ag(2)), and 11.1 ± 0.09 nm (Au). FFT analysis showed a cubic crystal structure for all NPs. Optically, Au-Ag(1) exhibited broad absorption (363–600 nm), Au-Ag(2) peaked at 546 nm, and Au at 521 nm. Devices with NP-modified electrodes showed enhanced short-circuit current density (JSC), with Au-Ag(2) reaching 7.19 mA/cm² and a PCE of 0.46%, compared to the reference JSC of 3.02 mA/cm² and PCE of 0.11%. Series resistance dropped from 23 Ω·cm² to 2 Ω·cm² (Au-Ag) and 5 Ω·cm² (Au).
