Abstract :
Surface processing was studied using a dc atmospheric nonthermal plasma jet with nitrogen gas as a method for preparing the glass plate with a fluorine-dope-tin-oxide membrane, coated with titanium oxide (TiO2) and sintered at 450degC for dye-sensitized solar cells. The results showed that characteristics of the TiO2 surface were enhanced by the dc atmospheric nonthermal plasma jet and, hence, the energy conversion efficiency increased by 1.3% as compared to samples without surface treatment. From the results of X-ray photoemission spectroscopy and spectroscopic analyses, it was found that the nitrogen radicals (condition from C3Piu toB3Pig) generated by the dc atmospheric nonthermal plasma jet were closely related with the enhancement of the energy conversion efficiency.
