ABSTRACT: In this paper, we report the indium tin oxide (ITO) films
deposited on the polyethyene terephthalate (PET) substrate,
which surface is treated with detergent solution. The ITO
films are deposited on room temperature by direct current (DC)
magnetron sputtering from a ceramic target of a 90% In-10%
Sn alloy. The deposited opto-electric ITO films on PET with
detergent treatment are 83.4% average visible transparency,
and 5.8 × 10-4 Ω-cm resistivity, respectively.
And then, we use the spin coating to form the polymer solar
cell. Under optimal conditions of surface treatment and film
deposition, the experimental result shows 2.12% of the power
conversion efficiency (PCE), which is suitable for the solarcell buoy applications.
