These films of ∼ 200 to 240 nm thickness with low and high vanadium loading, were grown by rf-magnetron sputtering on Si (100) and glass substrates at room temperature (RT) and 200 °C, respectively, using Zn1−xVxO nanopowder like targets. In regard to this, it should be noted that Zn1−xVxO nanopowder were successfully synthesized by sol-gel process. The controlled growth of these films is optimized by structural, morphological, optical and electrical characterization, and thus is confirmed by several techniques such as X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray Spectroscopy (EDS), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM). UV-Vis-NIR study of the samples shows a variable behavior (optical bandgap energy) depending on the vanadium content and also according to the temperature of the thin-layers deposition, which can be explained by the formation of the excited states. The resistivity of these thin films was then assessed. An increased resistivity was observed for layers developed with high vanadium loading at 200 °C. These remarkable properties of thin films developed through this research are expected to provide potential applications in the TCO and buffer-layers.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133446541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathematically, the appliance scheduling problem is formulated as an integer programming problem in which the decision variables consist of finding the optimal starting times of appliances under a time-varying electricity prices and the time windows in which the appliances must be operated. The aim is to minimize the two conflicting objectives simultaneously: The electricity cost and the discomfort caused by the delay or the advance of the appliances starting times from the preferred starting times set by a home consumer. The extreme solutions of the obtained pareto front; best cost solution and best discomfort solution, are compared with the reference case in which a home consumer starts his/her appliances on his/her preferred starting times. The simulation results show that the ability of the proposed algorithm to shift appliances consumption in response to time-varying electricity prices from the on-peak price periods to the off-peak price periods within the time windows of appliances, through which a home consumer may reduce electricity cost without a significant impact on his/her comfort.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130049525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field-scaled wind conditions are defined and used in the current study. They are designed after the case of QEERI solar test facility in Doha, Qatar, using a modeling approach based on Computational Fluid Dynamics. The modeling and simulation of such standardized ‘wind’ conditions are defined using on-field wind data collected at 2 m and 5 m. The statistics behind the experimental wind measurements are then used to calibrate the air velocity and the atmospheric boundary layer turbulence conditions for the proposed field model. The main purpose of the approach is to characterize general wind speed profiles expected in the PV arrays' vicinity, due to district buildings. Particularly, further studies can proceed with heat analyses and investigating the air flow influenced by the PV arrays and modules within the field itself. Due to the temperature effect that impacts the PV modules' performance, such approach can help predict PV plants performance under similar harsh weather conditions.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"8 Suppl A 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124495692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The μc-Si:H film serves as an active intrinsic absorber layer for a PIN configuration solar cell. A seed polysilicon (P+) layer was created by depositing amorphous silicon by ECR-PECVD method (using SiH4/Ar gases) directly on Al substrate followed by thermal annealing at 550°C resulting in a layer exchange. The μc-Si:H films was then deposited using a SiH4/H2 gas mix employing the same reactor. The optimization of deposition parameters was carried out on mono crystalline-Si wafers. The parameters which allowed to reaching the highest crystalline fraction of ∼ 65% are obtained for SiH4=4 sccm, H2=40 sccm and a deposition temperature of 480°C. The Raman spectroscopy was carried out on the deposited films to determine the crystalline fraction while the spectroscopic ellipsometry measurements were applied to get an insight on the optical constants of the deposited layers as well as on their thickness. X-ray diffraction (XRD) measurements were taken to identify the crystalline phase of the deposited film and surface morphologies of films were observed by scanning electron microscopy (SEM).","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131986635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
