“…Modifications of the structural, morphological, optical, chemical, electronic, and physicochemical properties of the ZnO semiconductor nanomaterials either through doping or through the formation of composites have always attracted the researcher to synthesize such materials [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. Various doped ZnO nanomaterials have been recently synthesized and explored for their photocatalytic [ 10 , 11 , 12 ], gas sensing [ 13 , 14 ], photonic crystals [ 15 ], spintronics [ 16 ], electrochemical sensing [ 17 , 18 , 19 ], optoelectronics [ 20 , 21 ], dye-sensitized solar cells [ 22 ], light emitting diodes [ 23 ], field emission transistors [ 24 , 25 ], and many more applications.

Herein, we report the growth of In-doped ZnO (IZO) nanomaterials, i.e., stepped hexagonal nanorods and nanodisks by the thermal evaporation process using metallic zinc and indium powders in the presence of oxygen. The as-grown IZO nanomaterials were investigated by several techniques in order to examine their morphological, structural, compositional and optical properties. The detailed investigations confirmed that the grown nanomaterials, i.e., nanorods and nanodisks possess well-crystallinity with wurtzite hexagonal phase and grown in high density. The room-temperature PL spectra exhibited a suppressed UV emissions with strong green emissions for both In-doped ZnO nanomaterials, i.e., nanorods and nanodisks. From an application point of view, the grown IZO nanomaterials were used as a potential scaffold to fabricate sensitive phenyl hydrazine chemical sensors based on the I–V technique. The observed sensitivities of the fabricated sensors based on IZO nanorods and nanodisks were 70.43 μA·mM−1·cm−2 and 130.18 μA·mM−1·cm−2, respectively. For both the fabricated sensors, the experimental detection limit was 0.5 μM, while the linear range was 0.5 μM–5.0 mM. The observed results revealed that the simply grown IZO nanomaterials could efficiently be used to fabricate highly sensitive chemical sensors.

“…DSSC is a solar cell composed of several components where it is possible to do modifications in an attempt to improve the performance of these solar cells. Amended modifications include dye replacement (Khuzaifah, 2014), redox electrolyte replacement (Hardian et al, 2010), variations to semiconductors (Parthiban et al, 2015), to the various methods used for DSSC fabrication.…”

Dye Sensitized Solar Cell (DSSC) is a device for light conversion to be electrical energy based on the concept of semiconducting sensitivity of the wide gap. This study aims to synthesis nanoparticles of ZnO: Zr semiconductors and tested the performance of ZnO: Zr nanoparticles on the DSSC system. ZnO Doped Zr Nanoparticles from precursor by Science and Technology Acceleration Center of National Nuclear Energy Agency (PSTA BATAN) Yogyakarta production was synthesized by gel-combustion method, and tested its performance on DSSC system. Effect of doping concentration variation Zr (0, 1, 3 and 5%) on the structure crystals and optical properties of ZnO studied by X-ray diffraction, infra-red spectra, and UV-Visible absorbance spectra. In this study also studied about the effect of Zr doping on changes in the parameters of crystal structures such as distances between fields of crystals , crystals lattice (a and c), unit cell volume, crystallite size, microstrain (ε), dislocation density (δ), and the textural coefficient . The synthesized nanoparticles meet the criteria 3-dimensional nanostructure of hexagonal wurtzite crystals. Uptake ZnO infrared radiation shows an increase in intensity as well shift in wave number 610 - 400 due to doping Zr. Doping Zr also influences the electronic structure of semiconductors characterized by the change of bandgap energy from 3,10-3,05 eV. Semiconductor performance test nanoparticles on the DSSC system showed a 1% Zr doping concentration increasing the voltage by 174 mV and the stability of the solar cell than the cell ZnO solar without doping that produces a voltage of 128 mV.

“…It can be fabricated as either of the two different types, the electrochemical type based on liquid redox electrolyte or the all‐solid state type, which is based on a solid hole conductor . Previous research on the DSSC shows that the use of nanoscale concepts has given a major improvement to the solar photon conversion. Recently, a conversion efficiency of 14% was reported by using collaborative sensitization by silyl‐anchor and carboxy‐anchor dyes under simulated sunlight.…”

SUMMARYThe dye-sensitized solar cell (DSSC) provides a clean, renewable, and cheap energy source. Since the beginning of the 1990s, DSSC has seen enormous development because of an increase in world energy consumption and the concerns about the environmental impact associated with combustion of fossil fuels. However, the efficiency of the DSSC to be a competitive energy source has not been achieved. In this work, we analyzed the effect of various materials parameters and environmental conditions on the performance of DSSC. To maintain the optimum performance for DSSCs and to enhance the energy and exergy efficiency in practical application environments, it is recommended to have the porous thin film TiO 2 at porosity of 0.40, thin film thickness of porous TiO 2 at 0.0005 cm, thickness of redox electrolyte at 0.0002 cm, diffusion coefficient of 0.0002 cm 2 s À1 , electron diffusion length of 0.0013 cm, and operating temperature of 300 K with light intensity of 100 mW cm À2.
