Highly responsive and low-cost ultraviolet sensor based on ZnS/p-Si heterojunction grown by chemical bath deposition

Photovoltaic Response of Heterojunction Photodiode based on Ba0.8Sr0.2TiO3 Nanorod Film

“…The abundance of electrons in the film helps to absorb the incident photons on the film, which affects the properties of the film and may cause these electrons to re-union with the holes. [23][24][25][26][27] The Semi logarithmic diagram of open circuit voltage vs light intensity for BST/Si device is shown in Fig. 8.…”

Adsorption Study of Congo Red Dye from Synthetic Wastewater at Different Concentrations Using Zinc Sulfide Nanoparticles

“…During the last decade, ZnS nanoparticles have attracted much attention due to their remarkable properties, such as direct and wide bandgap (3.7 eV) [ 15 ], two crystalline forms (Blende at room temperature, and Wurtzite at higher temperature), low toxicity, thermal stability. The ZnS nanostructures provide a diverse number of applications such as solar cells [ 10 ], biosensors, chemical sensors [ 11 ], and photocatalysis [ 27 ]. To further verify the potential application of ZnS nanoparticles as photocatalysts for studies of efficiently degrading dyes in aqueous industrial effluents [ 5 , 15 ], Table 1 compares and summarizes the results related to the variation in degradation efficiency using ZnS for various dyes.…”

“…As a result, the ZnS can be used as a catalyst, in UV–visible light-emitting diodes, flat-panel shows, infrared windows, etc. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Because of the numerous applications for ZnS, significant effort has been spent on the preparation of ZnS nanostructures using various methods such as solid-state reaction, chemical precipitation, microwave-assisted solvothermal, hydrothermal, etc.…”

“…[ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. The technique of synthesis has a considerable impact on the shape and control of the final product of ZnS, i.e., fabricating ZnS as bulk or nanostructures [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. There is a large folder in the literature that studies nanostructured ZnS and its properties and applications.…”

“…The ultrasonic spray pyrolysis is utilized to produce ZnS thin films to be used as an n-type layer in low-cost Cu 2 SnS 3 /ZnS thin-film heterojunction solar cells [ 10 ]. Similarly, a more reactive and less expensive UV sensor based on a ZnS/p-Si heterojunction produced through chemical bath deposition has been described [ 11 ]. The investigation of optical phonon modes and their overtones in resonant Raman scattering by ZnS or ZnS and ZnO quantum dots produced using the Langmuir–Blodgett process has been presented [ 12 , 13 ].…”
