摘要
We present herein some results on the fabrication and characterisation of n-type silicon nanoholes (SiNH)/poly(3,4-ethylene dioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) containing different graphene oxide (GO) hybrid solar cells. SiNH prepared by a chemical etching method showed a relatively low reflectance below 10% in the incident wavelength range of 300-1000 nm. The effect of GO concentrations on the performance of the hybrid solar cell was also investigated. The solar cell containing 0.5 wt% GO concentration had a maximum power conversion efficiency (PCE) of 9.07%, a V-oc of 0.519 V, a J(sc) of 26.85 mA cm(-2) and an FF of 65%, which is about 20% improvement compared to the device without GO (7.53%). The enhancement is attributed to the increase in electrical conductivity of the PEDOT:PSS coating layer due to the addition of the GO.
