“…This fact favored the increase of the intensity of (002) orientation, leading to a better structural ordering. This hypothesis was also confirmed by other authors using different dopants that also observed an increase of the roughness [30,31]. In addition, the increase of surface roughness endorsed oxygen absorption on the crystallites surface's which created dangling bonds performing as electron traps.…”

In this study, high transparent thin films were prepared by radio frequency (RF) magnetron sputtering from a conventional solid state target based on ZnO:MgO:Al2O3 (10:2 wt %) material. The films were deposited on glass and silicon substrates at the different working pressures of 0.21, 0.61, 0.83 and 1 Pa, 300 °C and 250 W of power. X-ray diffraction patterns (XRD), atomic force microscopy (AFM), UV-vis absorption and Hall effect measurements were used to evaluate the structural, optical, morphological and electrical properties of thin films as a function of the working pressure. The optical properties of the films, such as the refractive index, the extinction coefficient and the band gap energy were systematically studied. The optical band gap of thin films was estimated from the calculated absorption coefficient. That parameter, ranged from 3.921 to 3.655 eV, was hardly influenced by the working pressure. On the other hand, the lowest resistivity of 8.8 × 10−2 Ω cm−1 was achieved by the sample deposited at the lowest working pressure of 0.21 Pa. This film exhibited the best optoelectronic properties. All these data revealed that the prepared thin layers would offer a good capability to be used in photovoltaic applications.

“…The H 2 sensors made of metal ion doped SMONs were reported to exhibit high responses, although their response/recovery times were also reported to be longer than those made of the noble ion modified SMON-based RT H 2 gas sensors. 278,280,288,289 For example, Co-doped TiO 2 sensors exhibit an ultra-high response with a value of 4082 to 1000 ppm H 2 gas, although the response time is 66 s, which is quite slow for detection of highly explosive H 2 . 278 In summary, compared to those sensors made of noble metal nanoparticle modified SMONs, the improved effects of gas sensors made of the metal ion modified SMONs are not as significant.…”

“…Renewable energy and coal are the fastest developing power resources, with consumption increasing with the aid of 2.1 percent in line with year respectively. [7] The performance of a PV panel may be compromised by several reasons due to either installation failure or modifications of electrical and environmental popularity occurring at some point of the plant operation. Unsuitable orientation and inclination of sun surfaces are examples of set up screw ups.…”

This paper is primarily based on Internet of Things (IoT) in which real time monitoring of PV panel is completed with the assist of sensing nodes mounted on every PV panel. The acquired statistics' are transferred to a service centre and it's far discovered through website with the aid of the usage of Personal Home Page (PHP). To screen the PV panel, low fee clever multisensory structure is geared up. The sensors are voltage, present day, temperature, irradiance sensors. DMPPT set of rules is used to enhance the performance of the PV panel .The leakage modern-day from every panel is comments to supply. The polycrystalline kind PV panel is used to enhance the conductivity of the panel. The low yielding panel is detected without difficulty and changed. Based On software the burden can be automatically connected or disconnected to the PV panel. As a end result the overall performance of PV panel can be monitored at everywhere and every time through web site and also price of tracking machine is greatly reduced.
