Figure 3From: Effect of variation of average pore size and specific surface area of ZnO electrode (WE) on efficiency of dye-sensitized solar cellsXRD spectra of the mesoporous ZnO samples synthesized using different concentrations of NaOH. The concentrations used were 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, and 0.5 M. The samples were calcinated at 315°C for 12 h. The diffraction peaks are identified using the standard JCPDS data (card no. 01-071-6424).Back to article page
