Studies on the structural, morphological, optical and electrical properties of Al-doped ZnO nanorods prepared by electrochemical deposition

Improved efficiency of perovskite solar cells based on Ni-doped ZnO nanorod arrays and Li salt-doped P3HT layer for charge collection

“…The sharp and strong (002) reflection also indicates preferred crystallization of ZnO nanorods along the c-axis direction, i.e., vertical to the substrate surface. Moreover, the incorporation of Ni atoms can be deduced from two increased peaks indexed (100) and (101) compared to the strong (002) peak, which is due to the formation of stress-induced ion size difference between Zn and Ni and the segregation of Ni in grain boundaries [35]. The incorporation of Ni ions into the Zn site of the ZnO matrix is also verified by the energy dispersive X-ray (EDX) spectra (see the Appendix, Fig.…”

Gradient doping of Cu(I) and Cu(II) in ZnO nanorod photoanode by electrochemical deposition for enhanced photocurrent generation

“…The latter is interesting because it is inexpensive, achievable at low temperatures, allows modulating the morphology of ZnO (thin layers or high-quality nanostructures) by adjusting the deposition parameters (potential, current density, bath temperature and precursor concentration [25]). In addition, several literature studies have confirmed that doping ZnO nanocrystals with an adequate amount of Mg, Ni, Al , Fe and Cu [26][27][28][29][30][31], modifies its electrical, magnetical and optical properties. In particular, Cu is considered an interesting dopant due to its low cost and its many chemical and physical characteristic similar to those of Zn due to the similarity of its electronic structure, leading to the replacement of Zn by Cu in the low-energy ZnO lattice [32].…”

“…The lifetime of the photogenerated carriers is extended and the electron-hole pairs are effectively separated [49]. All electrodeposited ZnO films exhibited an anodic photo-current density, characteristic of a n-type semiconductor [26]. high transmittance and improved photo-current can be considered a preferable material for electro-optical UV applications and thin film based solar cells, as they require the use of materials with high optical transparency and electron conduction properties.…”

Electrical and optical properties of dip coated Al-doped ZnO thin films : Effect of Al-concentration, starting solution and sample ageing

“…Electrochemical deposition [14], Atomic layer deposition [15], Sol-gel technique [16][17][18] etc. Out of all above mentioned technique, Sol-gel technique is an attractive technique for obtaining thin films and has an advantage of easy control of the film composition and fabrication of small as well as large area thin films with low cost [19].…”
