The growth of ZnO nanostructures such as nanowire, nanoflower and nanorods
was carried out on FTO substrate. After growth of ZnO nanostructures were
used as the wide band gap semiconducting photoelectrode in dye sensitized solar
cell (DSSCs). Solar conversion efficiencies and incident photon-to-current
conversion efficiencies (IPCE) were investigated as depend on surface
morphology of ZnO nanostructures. The highest solar-to-electric energy
conversion efficiency of 3.1 % and IPCE of 34% was obtained by using the ZnO
nanoflowers/N719 dye/I-/I-3 electrolyte. In addition, Zn nanowires show solarto-electric energy conversion efficiency of 2.1% and IPCE of 25% while ZnO
nanorods show solar-to-electric energy conversion efficiency of 1.59% and
IPCE of 18%.
