Download or read book Laser Annealing of Amorphous Poly written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-05 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preliminary design proposed for the microelectronics materials processing equipment is presented. An overall mission profile, description of all processing steps, analysis methods and measurement techniques, data acquisition and storage, and a preview of the experimental hardware are included. The goal of the project is to investigate the viability of material processing of semiconductor microelectronics materials in a micro-gravity environment. The two key processes are examined: (1) Rapid Thermal Annealing (RTA) of semiconductor thin films and damaged solar cells, and (2) thin film deposition using a filament evaporator. The RTA process will be used to obtain higher quality crystalline properties from amorphous/poly-silicon films. RTA methods can also be used to repair radiation-damaged solar cells. On earth this technique is commonly used to anneal semiconductor films after ion-implantation. The damage to the crystal lattice is similar to the defects found in solar cells which have been exposed to high-energy particle bombardment. Cole, Eric E. Unspecified Center NAG5-1294...

Download or read book Laser Annealing of Semiconductors written by J Poate and published by Elsevier. This book was released on 2012-12-02 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser Annealing of Semiconductors deals with the materials science of surfaces that have been subjected to ultrafast heating by intense laser or electron beams. This book is organized into 13 chapters that specifically tackle transient annealing of compound semiconductors. After briefly dealing with an overview of laser annealing, this book goes on discussing the concepts of solidification and crystallization pertinent to the field. These topics are followed by discussions on the main mechanisms of interaction of photon and electron beams with condensed matter; the calculation of thermophysical properties of crystalline materials; and high-speed crystal growth by laser annealing of ion-implanted silicon. The subsequent chapters describe the microstructural and topographical properties of annealed semiconductor layers and the epitaxy of ion-implanted silicon irradiated with a laser or electron beam single pulse. This text also explores the electronic and surface properties and the continuous-wave beam processing of semiconductors. The concluding chapters cover various reactions in metal-semiconductor systems, such as fast and laser-induced melting, solidification, mixing, and quenching. Laser-induced interactions in metal-semiconductor systems and the factors involved in control of the heat treatment process are also discussed in these chapters. Materials scientists and researchers and device engineers will find this book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid technological developments during the later half of the 20th century have demanded materials that are stronger, capable of use at much higher temperatures, more corrosion-resistant, and much less expensive than those currently used. These demands become even more significant on the threshold of the new century and the millennium. Significant improvements in properties can only be achieved by processing the materials under far-from-equilibrium (or non-equilibrium) conditions. Several new processing technologies have been developed during the past few decades including, rapid solidification, spray forming, mechanical alloying, ion mixing, vapor deposition, laser processing and plasma processing. Remarkable advances have been made in recent years in the science and technology of these processes used to synthesize, characterize, and apply these materials processed under non-equilibrium conditions. Some of these techniques have evolved from laboratory curiosity to commercial-scale manufacturing in just a few years. In other cases, industrial necessity prompted development of the technology, and the science followed later. The chapters in this book have been written by people who are world-recognized experts in their respective fields. Each chapter describes the principles, processing techniques, special features of the materials produced, and their applications. An extensive list of references is provided at the end of each chapter that will facilitate location of additional information on specific aspects of any technique.

Download or read book High Efficiency Crystalline Silicon Solar Cells written by Eun-Chel Cho and published by MDPI. This book was released on 2021-01-06 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is composed of 6 papers. The first paper reports a novel technique for the selective emitter formation by controlling the surface morphology of Si wafers. Selective emitter (SE) technology has attracted renewed attention in the Si solar cell industry to achieve an improved conversion efficiency of passivated-emitter rear-contact (PERC) cells. In the second paper, the temperature dependence of the parameters was compared through the PERC of the industrial-scale solar cells. As a result of their analysis, PERC cells showed different temperature dependence for the fill factor loss as temperatures rose. The third paper reports the effects of carrier selective front contact layer and defect state of hydrogenated amorphous silicon passivation layer/n-type crystalline silicon interface. The results demonstrated the effects of band offset determined by band bending at the interface of the passivation layer and carrier selective front contact layer. In addition, the nc-SiOx: H CSFC layer not only reduces parasitic absorption loss but also has a tunneling effect and field-effect passivation. The fourth paper reports excimer laser annealing of hydrogenated amorphous silicon film for TOPCon solar cell application. This paper analyzes the crystallization of a-Si:H via excimer laser annealing (ELA) and compared this process with conventional thermal annealing. The fifth paper reports the contact mechanism between Ag–Al and Si and the change in contact resistance (Rc) by varying the firing profile. Rc was measured by varying the belt speed and peak temperature of the fast-firing furnace. The sixth paper reports a silicon tandem heterojunction solar cell based on a ZnO/Cu2O subcell and a c-Si bottom subcell using electro-optical numerical modeling. The buffer layer affinity and mobility together with a low conduction band offset for the heterojunction are discussed, as well as spectral properties of the device model.
