The morphological control of MEH-PPV films on an ITO electrode for hybrid solar cell fabrication
The poly[2-methoxy-5-(2-ethylhexyloxy-p-phenylene-vinylene)] (MEH-PPV) thin films were deposited on indium tin oxide (ITO) coated glass by using spin-coating technique at room temperature. The effect of spin-coating speed on the electrical and morphological properties of MEH-PPV film was studied. The surface roughness would be controlled by varied spin-coating speeds. I-V characteristics of ITO/MEH-PPV/Al structure have measured by solar simulator at the optimum condition.
