Abstract
AbstractSilver doped magnesium (Ag:Mg) bimetallic nanoparticles (BMNPs) were successfully synthesized using wet chemical processing. The collection of enhanced photocurrents is possible through metal nanoparticles in the photoactive layer of a thin‐film organic solar cell (TFOSC). This investigation employed poly‐3‐hexylthiophene(P3HT) and [6‐6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) polymer blend solar absorbers in a conventional device structure. The solar cell performances were found to depend on the concentration of Ag:Mg BMNPs in the photoactive medium. Consequently, significant device performance was recorded for the solar cells containing Ag:Mg BMNPs at all doping levels compared to the un‐doped devices. Therefore, the highest power conversion efficiency (PCE) of 4.11% was achieved at a 1.5 wt% doping level with a high fill factor of 56% compared to the reference cell. The performance improvement in PCE constitutes a 79% improvement, which is much higher than undoped solar cells. This result was attributed to the occurrence of the localized surface plasmon resonance effect (LSPR), which is favorable for boosting the optical absorption and charge transport processes in TFOSC.
