“…Regarding these additives, the development of inorganic/polymer nanocomposite materials has received significant interest due to the wide range of potential applications in optoelectronic devices [16,17] and electromagnetic interference shielding [18]. These 4 composites have been prepared by different techniques and they exhibit a synergetic behavior between the polymer and the inorganic material [8-12, 45,46, 19].…”

“…Nanostructures of ZnO such as ZnO nanorods and nanowires have received increased attention due to their excellent electrical and optical properties [3]. Due to the high surface-to-volume ratio provided by the one-dimensional (1D) nanostructure, ZnO nanorod arrays are considered suitable to the application for hybrid photovoltaic devices [4][5][6][7]. In the past few years, ZnO nanorods have been synthesized via various physical and chemical methods including vapor phase synthesis [8][9][10], metalorganic chemical vapor deposition (MOCVD) [11][12][13], and solution-based synthesis [14][15][16][17].…”

“…An example of such a hybrid solar cell is the one with ZnO nanorod arrays coated on ITO-coated glass substrates and they found that nanorods play an important role in improving electron transport speed [4][5][6][7]. In addition, it will be an innovation to build plastic hybrid solar cells [19] consisting of ZnO nanorods and conjugated polymer on ITO/PET substrates since plastic materials are cheap, lightweight, bendable, and suitable to large-scale roll-to-roll manufacturing.…”

We report a low-temperature aqueous solution growth of uniformly aligned ZnO nanorod arrays on flexible substrates. The substrate is Indium Tin Oxide (ITO) film coated on polyethylene terephthalate (PET). Solutions with five different concentrations of the precursors with equimolar Zinc Nitrate and Hexamethylenetetramine (HMT) in distilled water were prepared to systematically study the effect of precursor solution concentration on the structural and optical properties of ZnO nanorods. It was concluded that the precursor concentration have great influence on the morphology, crystal quality, and optical property of ZnO nanorods. The diameter, density, and orientation of the nanorods are dependent on the precursor solution concentration. X-ray diffraction and micro-Raman spectroscopy showed that the ZnO nanorods with the highest concentration of 50 mM were highly aligned and have the highest level of surface coverage. It was also found that the diameter and length of the nanorods increases upon increasing precursor solution concentration. This is the first systematic investigation of studying the effect of precursor solution concentration on the quality of ZnO nanorods grown on ITO/PET substrates by low-temperature solution method. We believe that our work will contribute to the realization of flexible organic-inorganic hybrid solar cell based on ZnO nanorods and conjugated polymer.

“…Unfortunately, the ZnO band gap (3.4 eV) is too large for use in efficient photovoltaic devices. 13 Nonetheless, this has not prevented numerous attempts to construct photovoltaics from this material, with schemes such as n-ZnO/p-CdTe thin film heterojunctions, 14,15 ZnO/CdSe composites, 16 n-ZnO/p-Cu 2 O heterojunctions, 17,18 n-ZnO/p-Si heterostructures, 19,20 ZnO-nanocrystal/organic-polymer hybrid photovoltaics, [21][22][23][24][25][26][27][28] and ZnO-nanocolumns as electrodes for dye-sensitized photoelectrochemical cells. 29 One idea to reduce the band gap of ZnO is to stack it with another environmentally benign and abundant material, such as ZnS.…”

Optical Properties of ZnO/ZnS and ZnO/ZnTe Heterostructures for Photovoltaic Applications

Although ZnO and ZnS are abundant, stable, environmentally benign, their band gap energies (3.44 eV, 3.72 eV) are too large for optimal photovoltaic efficiency. By using band-corrected pseudopotential density-functional theory calculations, we study how the band gap, optical absorption, and carrier localization can be controlled by forming quantum-well like and nanowire-based heterostructures of ZnO/ZnS and ZnO/ZnTe. In the case of ZnO/ZnS core/shell nanowires, which can be synthesized using existing methods, we obtain a band gap of 2.07 eV, which corresponds to a Shockley-Quiesser efficiency limit of 23%. Based on these nanowire results, we propose that ZnO/ZnS core/shell nanowires can be used as photovoltaic devices with organic polymer semiconductors as p-channel contacts.
