Özet:

 

ZnO- and Mg-doped ZnO samples are prepared by spray pyrolysis on conducting   glass substrates to fabricate ZnO-based dye-sensitized solar cells (DSSCs).   Influences of Mg-doping content on the power conversion efficiencies of   ZnO-based DSSCs are investigated. X-ray diffraction results show that all   the samples exhibit a hexagonal wurtzite structure. Scanning electron   microscopy data indicate that the ZnO sample has uniform rods with 1 μμ\mu m   diameter. With respect to ZnO, the band gap value of 4 at.% Mg-doped ZnO   samples improves to the value of 3.27 eV and a further increase in Mg level   up to 6 at.% gives rise to a decline in the band gap value of 3.22 eV.   Photoluminescence measurements illustrate that intensities of the   ultraviolet peak and a red luminescence peak take their maximum values for 4   at.% Mg doping. From solar cell performance measurements, the best power   conversion efficiency of 0.08% is obtained for the doping amount of 4   at.% Mg.
