Regenerative Fuel Cell (RFC) systems are used for the enhancement of sustainable energy aspect in conventional fuel cells. In this study, a photovoltaic-electrolyzer-fuel cell integrated cycle has been presented. The proposed system has been designed as a novel approach for alleviating the restrictions  on energy streams in the RFC systems. Modeling of the system has been performed from the mas...

In the last decade, examples of devices manufactured with SUMMiT technology have demonstrated the capabilities of polysilicon surface micromachining [1]. Currently we are working on enhancements to this technology that utilize additional structural layers of silicon nitride to enable Microfluidics and BioMEMS applications. The addition of the silicon nitride layers allows the fabrication of mic...

The self-assembling of three-dimensional (3-D) MEMS from polysilicon surface micromachined part is very attractive. To avoid risky external manipulation, the practical use of integrated actuator to perform the assembling task is required. To that goal, this paper presents detailed characteristics of the electrostatic surface micromachined scratch drive actuator (SDA). First, from numerous SDA t...

in this paper, the performance evaluation of a two-way hybrid photovoltaic/thermal (pv/t) solar collector was analytically and experimentally carried out. mathematical expressions for operating parameters in glass to glass and glass to tedlar pv/t solar collectors were developed and experimentally validated by a glass to tedlar pv/t solar collector system. also the influence of air flow rate on...

In this article, we investigate the passivation quality and electrical contact properties for samples with a 150 nm thick n + polysilicon layer in comparison to phosphorus diffused layer. High level of is achieved an interfacial oxide underneath it. The screen-printed fire-through silver paste a...

Solar grade silicon (SoGSi) is a key material for the development of crystalline photovoltaics (PV), which expected to reach tera-watt level in next years and around 50TW 2050. Upgraded metallurgical (UMGSi) has already demonstrated be viable alternative standard polysilicon terms cost quality. This study presents life cycle assessment (LCA) UMG obtained by FerroSolar process. Moreover, it show...

The main problemswith the use of fossil fuels is the restrictions on their access and the detrimental consequences of their use which causes a threat to human health and quality of life. Consequently, the use of other energy sources has become necessary. Renewable Energy as a permanent and clean energy source is an answer to this problem. One such energy source includes photovoltaic solar energ...

Background & Aims of the Study: The safe drinking water providing is one of the most crucial objections in these centenaries. Bacterial water contamination and high rate of morbidity and mortality is crucial health threat. Efficiency of potassium persulfat (KPS) associated solar disinfection as a novel water disinfection technology was evaluated in batch scale experiments, us...
