We report an environmentally friendly inkjet-printed indium sulfide (In2S3) buffer layer using benign chemistry and processing conditions. A pre-synthesized indium-thiourea compound is dissolved in a mixture of water ethanol, inkjet printed on Cu(In,Ga)(S,Se)2 absorber annealed air. The shows ?-In2S3 structure with few organic impurities band gap the range 2.3 eV. An ultraviolet ozone treatment...

3D CuInS2/TiO2 nanocomposite solar cell performance is strongly influenced by several structural factors, including cell thickness, buffer layer thickness, and the morphology of the TiO2 nanoparticulate matrix. To delineate the effect of these structural factors on photovoltaic performance, a series of parametric studies are performed where a single structural parameter is varied (TiO2 nanopart...

To develop Bi2S3-based heterojunction for efficient solar light induced photoreduction of Cr(VI), flower-like Bi2S3–In2S3 composites consisted nanorods were prepared via a microwave-assisted hydrothermal route. In contrast with pure Bi2S3, exhibited the enhanced activity while decreased adsorption capacity Cr(VI) removal. The best removal efficiency 70 mg L?1 solution (99.86%) was achieved by o...

This paper describes synthesis of In2S3 nanoparticles by sonochemistry method and their application to enhance solar cells performance which In2S3 nanoparticles work as co-sensitizer for the first time. In2S3 is a narrow band gap semiconductor (2 eV) with conduction band higher than TiO2. Therefore it can transfer electron to the conduction band of TiO2. The effect of different parameters such ...

A new type of doped Cd:In2S3 NC, which exhibits bright white-light emission with a QY of about 18%, synthesized by a one-pot G-doping synthesis approach is presented. The successful realization of temporal separation of nucleation doping and growth doping makes this approach a facile method to synthesize the In2S3/Cd:In2S3 core/shell nanostructure.

Unusual hierarchical stacked superstructures of cubic beta-In2S3 were fabricated via a facile hydrothermal process in the presence of a surfactant cetyltrimethylammonium bromide CTAB; the 3D superstructures were developed by helical propagation of surface steps from microflakes of 10-20 nm thickness.

The development of efficient heterojunction photocatalysts with a facilitated charge carrier separation rate and improved light-harvesting capacity is still challenging issue for effectively solving environmental pollution. Herein, one-step refluxing process was employed to construct 2D/2D CdIn2S4/In2S3 (CISI) an intimate interface between these two components. crystal structure, morphology, ca...

The performance of the Cu2ZnSnS4 based solar cell is investigated using a simulation program called Solar Cell Capacitance Simulator (SCAPS). The cell structure is based on Cu2ZnSnS4 (CZTS) compound semiconductor as the absorber layer, n-doped and un-doped (i) zinc oxide as the window layer, In2S3 as the buffer layer. We study the influence of the defect density, carrier density, thickness of t...

Abstract To develop an advanced artificial intelligent optoelectronic information system, to accurately simulate the photonic nociceptors, like process of activation a human visual nociceptive pathway, is great significance. The visible light reaches retina for perception, but its excessive exposure can cause tissue damage. However, there are relatively few reports on light-triggered nociceptor...
