Abstract

Surface modification of ZnO nanorods with diluted P3HT in inverted hybrid solar cell was studied. ZnO nanorods were grown on ZnO nanoparticles-coated FTO substrate via chemical bath deposition. 0.2 mM solution of Eosin-Y was spin-coated onto ZnO nanorods at a spinning speed of 1000 rpm for 60 s. Diluted P3HT (0.5 mg/ml) was then coated on ZnO nanorods by using two different methods, namely spin coating and immersion technique. The fabrication process was followed by depositing P3HT from a 25 mg/ml solution. A device without surface modification was also made for comparison. The structure of the devices was FTO / Eosin-Y-coated ZnO nanorods/P3HT/Ag. The optical properties of the samples were investigated and the devices performance was characterized by IV measurement under 100 mW/cm2 simulated AM 1.5G sunlight. It was found that device coated with diluted P3HT via immersion method showed the highest efficiency, followed by without surface modification and that coated with diluted P3HT using spin coating method.
