Abstract
In this article we report the photovoltaic properties of devices made using a highly conducting polymer electrode, from poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) incorporated with ZnSe nanoparticles on ITO substrate as an anode and a Poly(3-hexylthiophene-2,5-diyl) (P3HT) mixed with Phenyl-C61-butyric acid methyl ester (PC61BM) in the ratio of 1:1 as the active layer. The device performance was compared with that of devices made with PEDOT-PSS without ZnSe nanoparticles on ITO substrates. The IV characteristics were studied and the surfaces of PEDOT:PSS with ZnSe were imaged using Transmission electron microscopy (TEM). It shows that the functions of the photodiode devices increase with the addition of ZnSe nanoparticles. The improvement is linked to two physical effects: the increased scattering efficiency of the fine ZnSe nanoparticles and .
