Silver Nanoparticles in PEDOT:PSS Layer for Polymer Solar Cell Application


International Journal of Photoenergy












polymer solar cells, PEDOT:PSS, silver


We compare the performance of polymer solar cells based on poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) with silver nanoparticles (Ag NPs) incorporated in poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS).The structure of constructed solar devices was ITO/PEDOT:PSS:AgNPs/P3HT:PCBM/Al. Typical polyol chemistry was used to synthesize silver in water solution. Ag nanoparticles were investigated by UV-vis, atomic force microscopy (AFM), and dynamic light scattering (DLS) methods. We investigated influence of amount of silver in a hole transporting layer on the performance of bulk heterojunction polymer solar cells. The value of power conversion efficiency (PCE), equal to 2.16% under simulated 100mW/cm2 AM1.5G irradiation, was found for device created in airwith 60 μL ofAgNPs added to 1mL of PEDOT:PSS. Along with the increase amount of Ag NPs from 60 to 150 μL, the PCE decrease was found. Stability of solar cells with Ag was also investigated. The loss in value of PCE after 8 months was found in the range 13-47% depending on the device architecture. The solar cells were additionally measured with impedance spectroscopy.
