Abstract

Dye-Sensitized Solar Cell (DSSC) have been attracting huge attention because of their efficiency, simple and low-cost fabrication process. In comparison to a commercially available silicon solar cell, DSSC can be produced at a lower cost per generated power [1]. This project will use chitosan as a binder to the ZnO photoanode to analyse the performance of dye-sensitized solar cell. The chitosan has been prepared by four different techniques. The obtained chitosan was characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Xray diffraction (XRD). Samples of white powder chitosan with degree of deacetylation of 78% were obtained, as determined by FTIR spectra. The similar chitosan was used to fabricate a dye-sensitized solar cell using 6% of chitosan and achieving voltage value of 0.2783V and current value of 0.2519A. A simulation using GPVDM software were done by varying the thickness of chitosan and manage to obtain the highest efficiency of 2.7645% with 160nm thickness layer of chitosan.
