Photoelectrocatalytic Degradation of Organic Pollutants in Aqueous Solution Using a Pt‐TiO2 Film
International Journal of Photoenergy - Tập 2009 Số 1 - 2009
Chun He, Mudar Abou Asi, Ya Xiong, Dong Shu, Xiangzhong Li
A series of Pt‐TiO2 films with nanocrystaline structure was prepared by a procedure of photodeposition and subsequent dip‐coating. The Pt‐TiO2 films were characterized by X‐ray diffraction, scanning electronic microscope, electrochemical characterization to examine the surface structure, chemical composition, and the photoelectrochemical properties. The photocatalytic activity of the Pt‐TiO2 films... hiện toàn bộ
Hydrothermal Synthesis of Iodine-Doped Nanoplates with Enhanced Visible and Ultraviolet-Induced Photocatalytic Activities
International Journal of Photoenergy - Tập 2012 - Trang 1-12 - 2012
Jiang Zhang, Zheng‐Hong Huang, Yong Xu, Feiyu Kang
The iodine-doped Bi2WO6(I-BWO) photocatalyst was prepared via a hydrothermal method using potassium iodide as the source of iodine. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM) and selected area electron diffraction (SAED), X-ray photoelectron spectroscopy (XPS), UV-vis diffuse reflectance spectroscopy (DRS), ... hiện toàn bộ
The Compromise Condition for High Performance of the Single Silicon Heterojunction Solar Cells
International Journal of Photoenergy - - 2012
Lee, Youngseok, Dao, Vinh Ai, Kim, Sangho, Kim, Sunbo, Park, Hyeongsik, Cho, Jaehyun, Ahn, Shihyun, Yi, Junsin
For optimum performance of the hydrogenated amorphous silicon/crystalline silicon (a-Si : H/c-Si) heterojunction solar cells, featuring a doping concentration, localized states, as well as thickness of emitter layer are crucial, since Fermi level, surface passivated quality, and light absorption have to be compromised themselves. For this purpose, the effect of both doping concentration and thickn... hiện toàn bộ

Effect of Subgrains on the Performance of Mono-Like Crystalline Silicon Solar Cells
International Journal of Photoenergy - Tập 2013 - Trang 1-8 - 2013
Su Zhou, Chunlan Zhou, Wenjing Wang, Yehua Tang, Jingwei Chen, Baojun Yan, Yan Zhao
The application of Czochralski (Cz) monocrystalline silicon material in solar cells is limited by its high cost and serious light-induced degradation. The use of cast multicrystalline silicon is also hindered by its high dislocation densities and high surface reflectance after texturing. Mono-like crystalline silicon is a promising material because it has the advantages of both mono- and multicrys... hiện toàn bộ
Economic Feasibility for Recycling of Waste Crystalline Silicon Photovoltaic Modules
International Journal of Photoenergy - Tập 2017 - Trang 1-6 - 2017
Idiano D’Adamo, Michela Miliacca, Paolo Rosa
Cumulative photovoltaic (PV) power installed in 2016 was equal to 305 GW. Five countries (China, Japan, Germany, the USA, and Italy) shared about 70% of the global power. End-of-life (EoL) management of waste PV modules requires alternative strategies than landfill, and recycling is a valid option. Technological solutions are already available in the market and environmental benefits are highlight... hiện toàn bộ
In‐situ investigations of the photoluminescence properties of SiO2/TiO2 binary and Boron‐SiO2/TiO2 ternary oxides prepared by the sol‐gel method and their photocatalytic reactivity for the oxidative decomposition of trichloroethylene
International Journal of Photoenergy - Tập 5 Số 1 - Trang 31-36 - 2003
Kyeong Youl Jung, Seung Bin Park, Masaya Matsuoka, Masakazu Anpo
Photoluminescence behavior of TiO2, SiO2/TiO2 binary and Boron‐SiO2/TiO2 ternary oxides prepared by the sol‐gel method was investigated. The differences in their photocatalytic reactivities of TiO2‐based photocatalysts were interpreted in terms of the relationship of the difference in their photoluminescence characteristics. The addition of SiO2 into TiO2 matrix induced new photoluminescence sites... hiện toàn bộ
A Review on Development Prospect of CZTS Based Thin Film Solar Cells
International Journal of Photoenergy - Tập 2014 - Trang 1-11 - 2014
Xiangbo Song, Xu Ji, Ming Li, Weidong Lin, Xi Luo, Hua Zhang
Cu2ZnSnS4is considered as the ideal absorption layer material in next generation thin film solar cells due to the abundant component elements in the crust being nontoxic and environmentally friendly. This paper summerized the development situation of Cu2ZnSnS4thin film solar cells and the manufacturing technologies, as well as problems in the manufacturing process. The difficulties for the raw mat... hiện toàn bộ
Improved Fractional Order VSS Inc-Cond MPPT Algorithm for Photovoltaic Scheme
International Journal of Photoenergy - Tập 2014 - Trang 1-10 - 2014
R. Arulmurugan, N. Suthanthira Vanitha
Nowadays a hot topic among the research community is the harnessing energy from the free sunlight which is abundant and pollution-free. The availability of cheap solar photovoltaic (PV) modules has to harvest solar energy with better efficiency. The nature of solar modules is nonlinear and therefore the proper impedance matching is essential. The proper impedance matching ensures the extraction of... hiện toàn bộ
Studies of Dye Sensitisation Kinetics and Sorption Isotherms of Direct Red 23 on Titania
International Journal of Photoenergy - Tập 2008 Số 1 - 2008
Peter J. Holliman, Beatriz Vaca Velasco, Ian R. Butler, Maarten Wijdekop, David Worsley
Sorption kinetics and isotherms have been measured for a commercial dye (Direct Red 23) on different samples of powdered Titania, and the data were analysed to better understand the dye sensitization process for dye sensitised solar cells (DSSCs). For the sorption kinetics, the data show rapid initial sorption (<1 hour) followed by slower rate of increasing uptake between 1 and 24 hours. While hig... hiện toàn bộ
