Available in PDF, EPUB and Kindle. Book excerpt: Ellipsometry is an experimental technique for determining the thickness and optical properties of thin films. It is ideally suited for films ranging in thickness from sub-nanometer to several microns. Spectroscopic measurements have greatly expanded the capabilities of this technique and introduced its use into all areas where thin films are found: semiconductor devices, flat panel and mobile displays, optical coating stacks, biological and medical coatings, protective layers, and more. While several scholarly books exist on the topic, this book provides a good introduction to the basic theory of the technique and its common applications. The target audience is not the ellipsometry scholar, but process engineers and students of materials science who are experts in their own fields and wish to use ellipsometry to measure thin film properties without becoming an expert in ellipsometry itself.

This book was released on 2017 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of recent advances in photovoltaics technology, renewable energy generated by the sun has become a viable alternative to traditional sources of energy. Photovoltaic modules composed of thin film solar cell devices offer several advantages over standard wafer based silicon modules, including high throughput automated production and reduced materials usage and cost. Spectroscopic ellipsometry (SE) is an important measurement tool capable of aiding high throughput manufacturing processes for thin films. SE is a non-destructive measurement technique well suited to measure and track parameters critical to photovoltaic device performance such as layer thicknesses, as well as optical and electrical properties of the layer components. This dissertation seeks to extend the application of SE via an expanded-beam method to large area photovoltaic modules while retaining the high measurement speeds of single spot measurements with collimated beams. The transition of ellipsometers as laboratory instruments to ones suitable for high throughput manufacturing lines poses unique challenges. The construction of a rotating compensator ellipsometer suitable for industrial applications is addressed with an emphasis on measurement speed. Schemes are evaluated to correct SE data for the inherent misalignments present in large area measurements of full-scale panels. In particular, consideration is given to the problems of oscillations due to compensator misalignment, effects of glass stress and overlap of reflected beams in through-the-glass measurements, and off-plane corrections due to large area substrate curvature. Expanded-beam SE was developed and applied for in situ, high-speed imaging/mapping analysis of spatial uniformity over large area multilayer coated substrates used in roll-to-roll thin film photovoltaics (PV). Slower speed instrumentation available for such analysis applies a 1D detector array for spectroscopic mapping and involves width-wise translation of SE optics over a conveyed substrate surface, measuring point-by-point in a time-consuming process. The expanded-beam instrument instead employs a 2D detector array with no moving optics, exploiting one array index for spectroscopy and the second array index for imaging across a line on a large area sample. Thus, the instrument enables imaging width-wise and mapping length-wise for evaluation of uniformity at the high linear substrate speeds required for real-time, in-situ, and inline analysis for roll-to-roll thin film PV. In this dissertation, the expanded beam technique is employed to study the components of a hydrogenated amorphous silicon (aSi:H) thin film photovoltaic device structure in the Ag/ZnO/n-i-p substrate configuration. The layers were deposited on a flexible substrate mounted on a roll-to-roll cassette. Ellipsometric measurements were performed using an expanded beam spectroscopic ellipsometer capable of simultaneously measuring 41 locations across the width of the substrate to form a line image. Layer thicknesses and optical property maps were constructed from sets of line images generated using ellipsometric analysis techniques. These techniques apply a best fit structural model for the film stack and pertinent optical models for the constituent layers of the device structure.

This book was released on 2016-07-13 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on advanced characterization methods for thin-film solar cells that have proven their relevance both for academic and corporate photovoltaic research and development. After an introduction to thin-film photovoltaics, highly experienced experts report on device and materials characterization methods such as electroluminescence analysis, capacitance spectroscopy, and various microscopy methods. In the final part of the book simulation techniques are presented which are used for ab-initio calculations of relevant semiconductors and for device simulations in 1D, 2D and 3D. Building on a proven concept, this new edition also covers thermography, transient optoelectronic methods, and absorption and photocurrent spectroscopy.
