| 标题： Modeling and simulation of Metamaterials- Waveguide Solar Cells | |
| 摘要： Metamaterials or Left handed materials had initially predicted more than fifty years ago [1] and nowadays have been realized and rapidly attracted consideration and interests. These materials have unusual physical properties as negatives of both permittivity and permeability. This unusual property tends to capture and focus a large amount of the incident light leading to enhance light-trapping and absorption in some design waveguide structure model for solar cells [2]. In this study, we investigate systematically the light trapping in new waveguide structure solar cell model containing Metamaterials. High silicon solar cell efficiency requires minimization of the optical losses [3]. Consequently, several mechanisms for light trapping capable to reduce both the reflection from the top surface of the cell and the transmission at it’s back, have been developed [4]. This paper deals with straightforward structures where a metamaterial layer is inserted between a semi-infinite glass cover layer and a silicon substrate layer [5]. According to the application of the transfer matrix method, a significant increasing of the absorption over a broadband light spectrum is obtained. To improve more the absorption of this structure, some different opaque layers are added on the rear side of the silicon layer in various structures solar cells. The obtained promising results could be used for design some future solar cells. | |
| 简介： Mohammad M. Shabat, was born in Beit Hanoun, Gaza Strip, Palestine in 1960. He received his B.Sc. in Physics from Al-Aazhar University, Cairo, Egypt in 1984 and the Ph.D. degree from the University of Salford, U.K. in 1990. He was a Research Fellow at the University of Manchester Institute of Science and Technology, UK, from 1989 to 1992. In April 1992, he joined the Physics Department at the Islamic University of Gaza (IUG) as an Assistant Professor of physics. He became an Associate Professor in 1996 and a Professor of Physics in 2000. In the period 2001-2005, he was the Vice President for Administrative Affairs at IUG and the Vice President for the Academic Affairs at the IUG between 2009-2013. He was awarded the Shoman Prize for a Young Arab Scientist (Jordan) in 1995, and the Humboldt Research Fellowships in 1998-99 at the Center of Semiconductor Technology and Opto-electronics, Duisburg-Essen University, Germany. He was a visiting scientist at Bochum University, Germany, in 1994; at the Institute National Polytechnic de Grenoble, (INPG), France, in 1995; at Salford University, U.K, in 1997; ICTP, Trieste, Italy, in 1996,1997 and 1998, 2000, 2001, 2003, 2004; Duisburg- Essen University, Germany, in1998, 1999 and 2002, 2003, 2004 and 2006, and 2007; Technical University of Warsaw in 2012; Frankfort University in 2012 and the Institute of Energy Research and Phyiscal Technologies (IEPT) at the Clausthal Technical University (TUC) in 2015. From 2006-2008, Prof. Shabat was a visiting Professor in Max Planck Institute for the Physics of Complex Systems, Dresden, Germany. Professor Shabat had received "Galileo Galilei" Award of the International Commission of Optics (affiliated to ICSU and IUPAP) in 2006. He was the Vice President for the Research and Graduate Studies at the IUG between 2013-2015. Professor Shabat became the first Distinguished Professor in the IUG in 2011. He was awarded the Distinguished Scholar Award, the Arab Fund Fellowship Program, Kuwait, 2007. He had been awarded the ISESCO Science Prize, 2010, and The TWAS Arab Regional Prize for 2016, Building Scientific Institutions, The World Academy of Sciences for the advancement of science in developing countries- Arab Regional Office), Egypt, 2016. He published more than 330 papers in international journals in optical science, physics, mathematics and education and presented many papers at local and international conferences. His research interests include nonlinear optical sensor, solar cells, renewable Energy, opto-electronics, magneto static surface waves, numerical techniques, applied mathematics, Nanotechnology and physics education. He supervised more than 40 postgraduate students (M.Sc and PhD) in mathematics and physics at Palestinian, Sudanese, Algerian and Egyptian universities. Recently he has established a Palestinian Optical Society (POS). He is an external examiner for BSc examinations, Msc dissertation and PhD theses in physics and mathematics at Palestinian and Egyptian universities. He is a senior member of IEEE, member of the Optical Society of America and fellow of TWAS who was the first fellow of TWAS in Palestine. | |
