Plasma treatment effect on dye-sensitized solar cell efficiency of hydrothermal-processed TiO2 nanorods.

摘要: Atmospheric plasma (AP) treatment was carried out on TiO2 nanorods (NRs) that were hydrothermally grown F-doped SnO2 (FTO)/glass. The effects of AP the surface NRs investigated, where involved use reactive gases H2, N2, and O2. energy AP-treated about 1.5 times higher than untreated (364.3 mJ/m2). After treatment, increase peak area ratios Ti2O3 peaks in XPS spectra resulted a decrease number oxygen vacancies NRs. efficiency dye-sensitized solar cell (DSSC) based N2-plasma-treated NRs, which approximately 1.11%, 79% DSSC
