Research ArticleOpen accessIn the keywordsEffects of the Contact Resistivity Variations of the Screen-Printed Silicon Solar CellShahrul Anizan, Khairymazalee Yusri, Cheow Siu Leong et al.Problem statement: Unmatched combination of emitter and base contact resistance will influence the total performance of the solar cell. To optimize this combination, single crystalline silicon solar cell was analyzed using quasi-one-dimensional transport of electrons and holes in crystalline semiconductor, PC1D. Approach: Effects of the resistance of the emitter and base contact have been investigated with a view to find … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 8,335 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpatial Distribution and Evaluation of Heavy Metal Pollution in Soil Based on Three-Dimensional Model and Kriging InterpolationBaoshun Liu, Yonghong Zhang, Jun Yao, Jian SuSoil heavy metal pollution is an important content for soil environmental governance. Based on the three-Dimensional (3D) geological modeling technology and ordinary Kriging method, this study described and analyzed the soil pollution status and spatial distribution characteristics of a site in Zhongshan, Guangxi. The results showed that combining 3D geological model and the Kriging interpolation method can well evaluate soil … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 10 Jun 2022 · 6,144 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermination of Morphometric Relationship and Condition Factors of Four Cichlids from Golinga Reservoir in Northern Region of GhanaElliot Haruna Alhassan, Daniel Nsoh Akongyuure, Francis AsumangLength-weight relationship and condition factor have severalapplications on fish biology, physiology, ecology and fisheries assessment. A six-month study was conducted from November 2013 to April 2014 to determine the length-weight relationship and condition factor of four major cichlids namely Oreochromis niloticus (Nile tilapia), Hemichromis fasciatus (Banded jewelfish), Sarotherodon galilaeus (Mango fish) and Tilapiazillii (Red-belly tilapia) to fill a knowledge gap … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 15 Aug 2015 · 8,201 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalyze the Absorption Properties and I-V Characterization of Dye Sensitized Solar Cell Using Ruthenium DyeAnees Ur Rehman, Farooq Aslam, Haseeb Ahmad KhanIn this study, Dye Sensitized Solar Cells (DSSC) has been fabricated using natural organic dye extracted from Ruthenium Dye and its I-V characterization and absorption properties have been analyzed. It is observed that the selected natural dye absorbed all visible light and supports electrons motion across the semiconductor interface. The dye acts as sensitizer because the titanium dioxide (TiO2) cannot … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 30 Dec 2014 · 7,391 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,983 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Rapid Thermal Annealing Towards the Performance of Screen-Printed Si Solar CellShahrul Anizan, Cheow Siu Leong, Khairymaza Lee Yusri et al.Problem statement: Solar cells are used to capture the photons which generate the energy. However the efficiency of the cells to turn the amount of photon to electricity needs to be high and so the cells enhancement is needed. This involved the whole process of the developing of the cells, thus annealing process is one of the important steps that … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,224 accessesView PDF Cite
