In the present study, SnO 2 nanoparticles were prepared by chemical precipitation method. The photoanode is fabricated using doctor-blade technique. In this paper, the dye molecules absorb light and make excited electrons the technique adopted, which in revolve create current in the output terminals of the cell. Graphite coated glass was used as the counter electrode. The prepared nanoparticles are characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and UV-Visible spectroscopy. XRD analysis confirms the structure of tetragonal structure with rutile phase, and crystallite sizes 20-30 nm. Curcuma longa dye extract used as photosensitizer. FTIR results show the M-O (Sn-O) bond with no other distinct impurities from the chemical reactions that were used for SnO 2 preparation. Finally, photocurrent-voltaic characterization of nano-crystaline natural dye solar cell using I-V studies. It was found that the levels of short-circuit current (Jsc), open-circuit voltage (Voc), fill factor (FF) and overall conversion efficiency (η) of Curcuma longa dye extract. Further suggestions to improve the efficiency of NDSSC are discussed.","PeriodicalId":187599,"journal":{"name":"Journal of Nanoscience and Technology","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126894806","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}

Polypyrrole/NiO doped NCs were prepared by in-situ chemical oxidative polymerization of pyrrole monomer. Here dopant NiO nanoparticles (NPs) were synthesized by solution combustion method using Aloe vera gel as fuel with ammonium per sulphate (APS) as oxidant. Different concentrations of NiO (10-50 wt%) NPs were incorporated into the polypyrrole. The synthesized nanocomposites were characterized by means of powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The size of the NPs were calculated by Scherer method, and found to be around 20 nm. TEM results are in consistent with the XRD results. The morphology of the obtained composites shows the porous and agglomerated particles which are due to large amount of gas evolution during NPs synthesis by solution combustion method and optical properties were studied.","PeriodicalId":187599,"journal":{"name":"Journal of Nanoscience and Technology","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126947631","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}
