Tuning charge transport properties using silver‐cobalt bimetallic nanoparticles is investigated to enhance the photo‐current collection in polymer solar cells. The silver‐cobalt nanoparticles were not only augmenting the charge transport processes but also expected to trap light by way of reflection. The polymers blend consisting of poly‐(3‐hexylthiophene) (P3HT):[6,6]‐phenyl C61 butyric acid methyl ester (PC61BM) is used in the fabrication of polymer solar cells. The experimental results indicated that the solar cells' performance depended on the concentration of Ag/Co in the hole transport layer (HTL). Nevertheless, the high‐power conversion efficiency value of up to 4.21% was observed, at the concentration of 0.1% by weight, which is much higher than pristine solar cells due to improved measured photocurrents from the devices. This is a significant improvement in PCE by 66.4% compared to the undoped transport medium. Ag/Co nanocomposite is found to be more stable under ambient laboratory conditions.

“…On the other hand, a limited range of optical absorptions, a thin layer of polymer solar absorber, and short exciton diffusion length in polymer medium determine the growth of PCE in PSC. Moreover, the low carrier mobilities of the conducting polymers and the short lifetime of the exciton restrict the active layer thickness below 200 nm, so it is not possible to boost optical absorption by merely increasing the thickness [8][9][10][11][12][13][14]. Thus, in addition to the absorber layer composition and device architecture, the PCE in TFPSCs depends on the augmentation of the open-circuit voltage and the fill factor (FF) [15][16][17].…”

Charge recombination is one of the critical factors that inﬂuence the performance of thin ﬁlm polymer solar cells (TFPSC). In this investigation metal, plasmonic nano-particles are employed to suppress charge recombination and energy loss in TFPSC. Trimetallic nano-composite was successfully synthesized, composed of copper, nickel, and silver (Cu/Ni/Ag) using wet chemistry. The nano-composite was incorporated into polymer based solar absorber layers at diﬀerent concentrations. The absorber layer is a fullerene-based bulk-heterojunction design using poly-3-hexylthiophene (P3HT) donor polymer. The results show that the power conversion eﬃciency (PCE) of the device doped with nano-composite has improved by 85% compared to the undoped one. The incorporation of tri-metallic nano-composite into the polymer blend solar absorber resulted in enhanced optical absorption and improved collection of photo-current as reﬂected by recorded high short circuit current density (Jsc) and ﬁll factor (FF). The enhancement of the performance is due to the occurrence of local surface plasmon resonances in polymer medium. The experiment indicated that there is some increment in an open circuit voltage, which is attributed to the low energy losses as the result of improved exciton dissociation, charge carrier transport, and collection.
