Promising results on the optical properties and morphology of deposited InxSy were found. In2S3 thin films were deposited onto glass substrates using thermal evaporation technique. Indium (In) and sulphur (S) powder were evaporated with different In/S ratio, where the stoichiometry and non-stoichiometry composition of InxSy influenced the optical bandgap and surface morphology. The films were structurally and optically characterized by X-ray diffraction, atomic force microscopy and UV measurements. It has been found that, the optical direct bandgap varied from 2.3 eV to 2.5 eV with the different composition ratio of InxSy. The X-ray diffraction data shows that the films have cubic ß-In2S3 structure onto the glass substrates. AFM images illustrate the surfaces quite smooth and uniform with a low surface roughness. These results can be explained in the practical work as non-stoichiometric composition of indium sulphide may result in different band gaps. Hence, a specific stoichiometric composition which results in the highest band gap is desirable to achieve high efficiency InxSy-CIGS solar cell. This is due to the lesser photon loss in the buffer layer as the light passes into the absorber layer. From the fabrication results, numerous influences of In2S3 buffer layer are investigated that can be implemented to the fabrication of high efficiency CIGS solar cells.","PeriodicalId":360345,"journal":{"name":"2011 IEEE Conference on Clean Energy and Technology (CET)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131129567","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}

Diesel and karanja oil and karanja biodiesel (10%, 20%, 30% and 40%) fuel blends were used to conduct engine performance and emission tests at varying loads in terms of 25% load increments from no load to full loads. Tests were carried out for engine operation and engine performance parameters such as fuel consumption, brake thermal efficiency, and exhaust emissions (smoke, CO, HC, NOx, and O2) were recorded. Among the blends KO10 and KB20 have shown a better performance with respect to BTE and BSEC. All KO blends have shown higher HC emissions after about 75% load. KB blends have shown 40–50% reduction in CO emissions compared to diesel at different loads. KO 40 blend showed a 21% reduction in NOx emission. KO10 and KB20 have an overall better performance with regards to both engine performance and emission characteristics.","PeriodicalId":360345,"journal":{"name":"2011 IEEE Conference on Clean Energy and Technology (CET)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126784797","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}

Nevertheless, only one measure, patent counts, has been widely used to identify the rate of improvement, and scant research has assessed the effectiveness of efforts to increase it. In this paper, the number of articles published on solar energy during each month in 1986-2009 is calculated to create a more detailed supplement to patent counts, and these article counts are used to assess certain relevant subsidies. A combination of counting articles manually and naïve Bayesian classification is used to overcome the difficulties of identifying which articles are relevant. The resulting monthly article counts are modeled as a function of two major subsidy types. The largest U.S. subsidy for renewable energy, the Production Tax Credit, appears to be as much as half as effective at encouraging solar technology research as federal solar research subsidies, despite the fact that the tax credit is given to electricity producers rather than to researchers and goes mostly to non-solar energy sources. This finding may be considered a preliminary example of the use of monthly solar article counts.","PeriodicalId":360345,"journal":{"name":"2011 IEEE Conference on Clean Energy and Technology (CET)","volume":"2 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126144270","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}
