nowadays, ii – iv group semiconductor thin films have attracted considerable attention from the research community because of their wide range of application in the fabrication of solar cells and other opto-electronic devices. cadmium zinc sulfide (zn-cds) thin films were grown by chemical bath deposition (cbd) technique. x-ray diffraction (xrd) is used to analyze the structure and crystallite ...

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 ...

in this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. for this, four reliability indices are considered in objective function;which are as follows: system average interruption frequency index (saifi), system averageinterruption duration index (sai...

cu(in,ga)se2 thin films (cigs) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of co-evaporated metallic precursors in se-containing environment under n2 gas flow. structural properties of prepared thin film were studied. to characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

Industrial tunnel oxide and passivated contact (i-TOPCon) solar cells were metallized at Fraunhofer ISE using ultrashort pulse laser ablation of the passivation layers for subsequent Ni/Cu/Ag plating process. The feature a SiOx n-type doped polysilicon layer covered by SiNx rear side, whereas front side is made boron emitter with AlOx/SiNx stack. reference i-TOPCon screen-printed supplier reach...

This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...

This paper presents the analysis, design, fabrication, and testing of a condenser microphone utilizing a thin low-stress polycrystalline silicon diaphragm suspended above a p+ perforated back plate. The microphone is fabricated using a combination of surface and bulk micromachining techniques in a single wafer process without the need of wafer bonding. The device shows sensitivities of -34 dB (...

Ion implantation, followed by annealing process, often leads to nonuniform doping and considerable depletion effect in the polysilicon gate of submicron MOS devices. Such an effect can alter notably the subthreshold characteristics and invalidate the conventional subthreshold current model. This paper studies the polysilicon-gate depletion effects on the subthreshold behavior based on results o...
