Abstract
Significant improvement of absorbance of regularly used Al/ZnO/poly (3-hexylthiophene) (P3HT): [6-6]-phenyl C61 butyric acid methyl ester (PCBM)/ poly(3,4-ethylenedioxythiophene)PEDOT/ Indium Tin Oxide (ITO) organic solar cell is achieved by inserting a scattering interface between ITO and PEDOT. The introduction of volumetric scattering mechanisms enhances the range of the absorbance spectrum and the absorbance of 100â¯nm active layer by 15%. There is an improvement of energy fluxby 34% at the centre of the spectrum and the generation rate increases roughly by 16% in the 450-750â¯nm window. The devices achieve a power conversion efficiency (PCE) of over 3.26% and an excellent external quantum efficiency (EQE) of 76.76%. The thick active layer in the device attenuates incident light almost completely without degrading the fill factor(FF) (69.6%-75.8%) and exhibiting a high short-circuit current density of 7.035â¯mA cmâ2.
