Book Amorphous and Microcrystalline Silicon Solar Cells Modeling Materials and Device Technology

Download or read book Amorphous and Microcrystalline Silicon Solar Cells Modeling Materials and Device Technology written by Ruud E.I. Schropp and published by Springer. This book was released on 2016-07-18 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous silicon solar cell technology has evolved considerably since the first amorphous silicon solar cells were made at RCA Laboratories in 1974. Scien tists working in a number of laboratories worldwide have developed improved alloys based on hydrogenated amorphous silicon and microcrystalline silicon. Other scientists have developed new methods for growing these thin films while yet others have developed new photovoltaic (PV) device structures with im proved conversion efficiencies. In the last two years, several companies have constructed multi-megawatt manufacturing plants that can produce large-area, multijunction amorphous silicon PV modules. A growing number of people be lieve that thin-film photovoltaics will be integrated into buildings on a large scale in the next few decades and will be able to make a major contribution to the world's energy needs. In this book, Ruud E. I. Schropp and Miro Zeman provide an authoritative overview of the current status of thin film solar cells based on amorphous and microcrystalline silicon. They review the significant developments that have occurred during the evolution of the technology and also discuss the most im portant recent innovations in the deposition of the materials, the understanding of the physics, and the fabrication and modeling of the devices.

Book Amorphous and Microcrystalline Silicon Technology 1997 Volume 467

Download or read book Amorphous and Microcrystalline Silicon Technology 1997 Volume 467 written by Michael Hack and published by Materials Research Society. This book was released on 1997-12-03 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the original focus of this long-standing series from the Materials Research Society was on hydrogenated amorphous silicon, the symposia have now expanded to incorporate microcrystalline silicon. The two, in fact, are very closely connected since the latter material can be grown by making comparatively small changes to the deposition conditions for amorphous silicon. This book offers an interesting variety of papers on deposition techniques, materials properties, characterization methods and devices - nearly all focused on thin-film forms of hydrogenated silicon. Topics include: Staebler-Wronski and fundamental defect studies in amorphous silicon; the story of hydrogen in amorphous silicon; photoelectric properties of amorphous silicon; deposition and properties of microcrystalline silicon; deposition studies for amorphous silicon and related materials; solar cells; thin-film transistors and sensors and novel device concepts.

Book Growth and Characterization of Hydrogenated Amorphous Silicon Prepared Using a Combined Hot Wire and Electron Cyclotron Resonance Plasma Deposition Technique

Download or read book Growth and Characterization of Hydrogenated Amorphous Silicon Prepared Using a Combined Hot Wire and Electron Cyclotron Resonance Plasma Deposition Technique written by Matthew Alan Ring and published by . This book was released on 2003 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hot Wire Chemical Vapor Deposition (HWCVD) is an emerging technology in semiconductor materials thin film deposition due to the high growth rates and reasonable electronic properties attainable using this method. To improve the electronic characteristics of material grown by the HWCVD method, neutral ion bombardment during growth was introduced as it is shown to be beneficial in Plasma Enhanced Chemical Vapor Deposition (PECVD). Neutral ion bombardment was accomplished by using remote Electron Cyclotron Resonance (ECR) plasma and the entire deposition technique is termed ECR-HWCVD. The ECR-HWCVD films were compared to HWCVD materials deposited without ion bombardment grown at similar conditions in the same reactor using a 10.5 cm filament to substrate distance to minimize substrate heating by radiation during deposition. The growth rate is halved when ion bombardment is added to HWCVD, however it remains four times greater than the highest quality ECR-PECVD films. Also, ECR-HWCVD material exhibited better electronic properties as shown by Urbach energy, photosensitivity, hydrogen content, microstructure parameters, and space charge limited current defect measurements. In addition, the effect of substrate temperature on hydrogen content and material microstructure was investigated. Both hydrogen content and the microstructure parameter R decreased as substrate temperature increased; and when ion bombardment was added to the deposition conditions, the microstructure parameter decreased regardless of substrate temperature.

Book Physics and Technology of Amorphous Crystalline Heterostructure Silicon Solar Cells

Download or read book Physics and Technology of Amorphous Crystalline Heterostructure Silicon Solar Cells written by Wilfried G. J. H. M. van Sark and published by Springer Science & Business Media. This book was released on 2011-11-16 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today’s solar cell multi-GW market is dominated by crystalline silicon (c-Si) wafer technology, however new cell concepts are entering the market. One very promising solar cell design to answer these needs is the silicon hetero-junction solar cell, of which the emitter and back surface field are basically produced by a low temperature growth of ultra-thin layers of amorphous silicon. In this design, amorphous silicon (a-Si:H) constitutes both „emitter“ and „base-contact/back surface field“ on both sides of a thin crystalline silicon wafer-base (c-Si) where the electrons and holes are photogenerated; at the same time, a-Si:H passivates the c-Si surface. Recently, cell efficiencies above 23% have been demonstrated for such solar cells. In this book, the editors present an overview of the state-of-the-art in physics and technology of amorphous-crystalline heterostructure silicon solar cells. The heterojunction concept is introduced, processes and resulting properties of the materials used in the cell and their heterointerfaces are discussed and characterization techniques and simulation tools are presented.
