Book Synopsis Silicon Based Thin Film Solar Cells by : Roberto Murri
Download or read book Silicon Based Thin Film Solar Cells written by Roberto Murri and published by Bentham Science Publishers. This book was released on 2013-03-20 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon Based Thin Film Solar Cells explains concepts related to technologies for silicon (Si) based photovoltaic applications. Topics in this book focus on ‘new concept’ solar cells. These kinds of cells can make photovoltaic power production an economically viable option in comparison to the bulk crystalline semiconductor technology industry. A transition from bulk crystalline Si solar cells toward thin-film technologies reduces usage of active material and introduces new concepts based on nanotechnologies. Despite its importance, the scientific development and understanding of new solar cells is not very advanced, and educational resources for specialized engineers and scientists are required. This textbook presents the fundamental scientific aspects of Si thin films growth technology, together with a clear understanding of the properties of the material and how this is employed in new generation photovoltaic solar cells. The textbook is a valuable resource for graduate students working on their theses, young researchers and all people approaching problems and fundamental aspects of advanced photovoltaic conversion.

Book Synopsis Trapping and Decay of Negative Charge in Silicon Nitride Films for Photovoltaic Applications by : Yongling Ren
Download or read book Trapping and Decay of Negative Charge in Silicon Nitride Films for Photovoltaic Applications written by Yongling Ren and published by . This book was released on 2011 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface passivation is a major technology area requiring improvement in order to increase device efficiency for most commercial solar cells. As the thickness of solar cells continues to decrease, surface passivation becomes even more important as the efficiency loss due to poorly passivated surfaces becomes greater. This thesis aims to combine the excellent passivation properties of silicon nitride (SiNsubscriptx) with the application advantages offered by corona charging to embed negative charges, particularly for the rear surface of conventional solar cells. Normal SiNsubscriptx film contains positive charges, which is often beneficial as it results in field effect passivation of n type surfaces. However, for p type surfaces, the positive charge in SiNsubscriptx induces a depletion region which increases recombination, and results in a parasitic shunt [1]. Therefore, the ability to trap negative charge in SiNsubscriptx for long periods of time could be of interest for solar cell applications.
Book Synopsis New Perspectives on Surface Passivation: Understanding the Si-Al2O3 Interface by : Lachlan E. Black
Download or read book New Perspectives on Surface Passivation: Understanding the Si-Al2O3 Interface written by Lachlan E. Black and published by Springer. This book was released on 2016-04-15 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses the problem of passivation at the surface of crystalline silicon solar cells. More specifically, it reports on a high-throughput, industrially compatible deposition method for Al2O3, enabling its application to commercial solar cells. One of the main focus is on the analysis of the physics of Al2O3 as a passivating dielectric for silicon surfaces. This is accomplished through a comprehensive study, which moves from the particular, the case of aluminium oxide on silicon, to the general, the physics of surface recombination, and is able to connect theory with practice, highlighting relevant commercial applications.
Book Synopsis Silicon Heterojunction Solar Cells by : W.R. Fahrner
Download or read book Silicon Heterojunction Solar Cells written by W.R. Fahrner and published by Trans Tech Publications Ltd. This book was released on 2006-08-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.

Book Synopsis Study of Charges Present in Silicon Nitride Thin Films and Their Effect on Silicon Solar Cell Efficiencies by : Vivek Sharma
Download or read book Study of Charges Present in Silicon Nitride Thin Films and Their Effect on Silicon Solar Cell Efficiencies written by Vivek Sharma and published by . This book was released on 2013 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: As crystalline silicon solar cells continue to get thinner, the recombination of carriers at the surfaces of the cell plays an ever-important role in controlling the cell efficiency. One tool to minimize surface recombination is field effect passivation from the charges present in the thin films applied on the cell surfaces. The focus of this work is to understand the properties of charges present in the SiNx films and then to develop a mechanism to manipulate the polarity of charges to either negative or positive based on the end-application. Specific silicon-nitrogen dangling bonds (·Si-N), known as K center defects, are the primary charge trapping defects present in the SiNx films. A custom built corona charging tool was used to externally inject positive or negative charges in the SiNx film. Detailed Capacitance-Voltage (C-V) measurements taken on corona charged SiNx samples confirmed the presence of a net positive or negative charge density, as high as +/- 8 x 1012 cm-2, present in the SiNx film. High-energy (~ 4.9 eV) UV radiation was used to control and neutralize the charges in the SiNx films. Electron-Spin-Resonance (ESR) technique was used to detect and quantify the density of neutral K0 defects that are paramagnetically active. The density of the neutral K0 defects increased after UV treatment and decreased after high temperature annealing and charging treatments. Etch-back C-V measurements on SiNx films showed that the K centers are spread throughout the bulk of the SiNx film and not just near the SiNx-Si interface. It was also shown that the negative injected charges in the SiNx film were stable and present even after 1 year under indoor room-temperature conditions. Lastly, a stack of SiO2/SiNx dielectric layers applicable to standard commercial solar cells was developed using a low temperature (400 °C) PECVD process. Excellent surface passivation on FZ and CZ Si substrates for both n- and p-type samples was achieved by manipulating and controlling the charge in SiNsubx
