This work investigates the effects of substituting natural sand with excavated soil in formulation hydraulic mortar developed from a self-compacting concrete (SCC). Four deposits were studied to assess their physicochemical properties. Subsequently, reference (RM) was designed using equivalent method. Furthermore, effect incorporating 30% excavation under different moisture conditions (natural storage conditions, dry and saturated surface state) on properties is studied. Spreading tests...
In this work, polyaniline (PANI) base-single wall carbon nanotubes (SWCNTs) composite counter electrode (CE) and N3 ruthenium dye sensitized TiO2, prepared using hydrothermal method, photoelectrode were assembled to form a solar cell (DSSC). Three different compositions (ITO/PANI, ITO/PANI-SWCNTs ITO/PANI-SWCNTs-graphite) of electrodes fabricated used for constructing DSSCs. The morphologies PANI-SWCNTs TiO2 mesoporous film surfaces investigated scanning electron microscope (SEM). electrical...
Eutectic molten salts are the most studied medium-high temperature thermal energy storage material due to their potential use in concentrated solar power plants. The aim of this work is investigate effect using reduced graphene oxide (RGO) and quantum dots (GQDs) on properties eutectic salts. A binary nitrate mixture NaNO3 KNO3 was selected as a base (BM) for nitrate/carbon-derivative composites. RGO GQDs were individually mixed with BM different fractions ranged from 0.1 1.5 wt %. results...
Organic–inorganic perovskite solar cells (PSCs) have been emerging as one of the most promising photovoltaic technologies. Surface morphology is considered a key-parameter in energy alignment and plays dominant role specifying device performance. The large grains low roughness enhance transport charge carriers from layers to layers, this reflects on delivered power conversion efficiency (PCE). Therefore, study, we investigated influence fabrication parameters grain size thereby PCE PSCs....
In this work, a novel dye sensitized solar cell (DSSC) structure -ITO/(TiO 2 /WO 3 )/N3dye/electrolyte/graphite/PANI/SWCNTs/ITO- was fabricated with different ratios of WO nanoparticles. It observed that the depositing layer nanoparticles- 3% wt. ratio- on TiO photoelectrode, enhances DSSC efficiency from 0.28 % to 1.2%. This is due reduction in charge injection resistance at electrolyte/photoelectrode interface.
In the operational process of dye sensitized solar cell (DSSC) photo excitation sensitizer is followed by electron injection into conduction band mesoporous oxide semiconductor. The molecule regenerated redox system, which itself restored at counter electrode electrons passed through load. Some in photo-electrode travel back to electrolyte, results a loss efficiency DSSC [1-2]. Therefore, it important suppress this recombination reaction and improve collection photo-injected for enhancing...
In this work, different locally fabricated adhesive materials were examined to be used as an encapsulant for producing of photovoltaic modules. All the selected samples characterized by FT-IR spectroscopy, TG instrument, UV-VIS spectrophotometer and electrical resistance meter. addition, all under investigation aging tests according IEC standards testing their stability durability. The polymethacrylate material with UV stabilizer can considered excellent commercial candidate module due its...
