“…6 In recent years, applications of ZnO nanostructures, particularly nanorods, in dye sensitized solar cells and thermoelectronics have attracted increasing interest. [7][8][9] In order to improve the optical and electrical properties of ZnO nanorods, group III elements such as Al, 10,11 Ga, 12,13 and In 14,15 can be used as cation dopants. Al-doped ZnO (AZO), Ga-doped ZnO (GZO), and In-doped ZnO (IZO) nanorods can be used as transparent electrodes in optoelectronic devices.…”

The structural and optical properties of the ZnO, Al-doped ZnO, Ga-doped ZnO, and In-doped ZnO nanorods were investigated using field-emission scanning electron microscopy, X-ray diffraction, photoluminescence (PL) and ultraviolet-visible spectroscopy. All the nanorods grew with good alignment on the ZnO seed layers and the ZnO nanorod dimensions could be controlled by the addition of the various dopants. For instance, the diameter of the nanorods decreased with increasing atomic number of the dopants. The ratio between the nearband-edge emission (NBE) and the deep-level emission (DLE) intensities (I NBE /I DLE ) obtained by PL gradually decreased because the DLE intensity from the nanorods gradually increased with increase in the atomic number of the dopants. We found that the dopants affected the structural and optical properties of the ZnO nanorods including their dimensions, lattice constants, residual stresses, bond lengths, PL properties, transmittance values, optical band gaps, and Urbach energies.

“…Therefore, the application of ZnO nanowires in DSCs is of great interest. However, reported efficiencies of ZnO nanowire solar cells are very low at present [5,[11][12][13][14]. One possible reason for the low efficiency may be that the surface area of the nanowire photoanode is not large enough.…”

Novel ZnO core/shell nanostructures were constructed by depositing a porous ZnO layer directly on the surfaces of pre-fabricated ZnO nanowires through a facile chemical method. The morphology and structure of the obtained products have been investigated by fieldemission scanning electron microscopy, high-resolution transmission electron microscopy and X-ray diffraction analysis. In these unique nanostructures, the porous overlayer exhibits a large surface area for sufficient dye loading to enhance light harvesting and the ZnO nanowire cores provide direct conduction pathways for the photogenerated electron transport to diminish the chance of electron recombination. The obtained ZnO nanostructures were used as photoanode material in dye-sensitized solar cell which showed an increase in performance of 141 % compared with an equivalent solar cell employing ZnO nanowire arrays as photoanode. This result was achieved mainly due to an increase in photogenerated current density directly resulting from improved light harvesting of the porous layer.

“…In order to improve the performance of the DSSCs, various treatments have been carried out, such as coated layer onto active materials [12] and doping of photovoltaic materials [13][14][15][16][17][18][19][20]. The materials are doped with metallic atoms, such as indium doped ZnO [13], cerium doped TiO 2 [14], stannum doped ZnO [15], boron doped ZnO [16], alluminium doped ZnO [17].…”

“…The doping with metallic and non-metallic materials can modify physical properties, such as morphology and optical properties. The performance of DSSCs was influenced by the morphology of active materials of photoanode [13][14][15]. The band gap of active materials was lowered down, increasing the rate of free electron-hole pair and consequently improves the performance of the cells [18][19][20][21][22].…”
