Abstract

Performance on dye-sensitized solar cells (DSCs) using a titanium dioxide nanoparticle layer treated by tetrafluoromethane gas plasma was investigated through electrical properties under illumination. A 50%-increase of maximum power density was observed in the plasmatreated DSCs when RF power and processing time are 1W and 100s, respectively. We also obtain diode factor between 1 and 2 in the fabricated DSCs from a plot of short-circuit current versus open-circuit voltage and then the calculated current density-voltage curve was good agreement with the experimental data.
