Book excerpt: This report describes work to form thin films of CuInSe2 (CIS) by annealing precursor films containing Cu, In, and Se in a rapid thermal processor. This involves two steps: (1) a precursor containing Cu, In, and Se is deposited on unheated substrates such that CIS does not form during this deposition step, and (2) the precursor is annealed in a rapid thermal processor to crystallize the CIS. Advantages of this process are that (1) no H2Se is used; (2) concentration gradients can potentially be built into the film due to the rapid anneal; and (3) the precursor can potentially be deposited using scalable methods such as sputtering, solution growth, and electrodeposition. The deposition method used was three-source, elemental physical vapor deposition. At room temperature, such a method was considered to be a flexible way to deposit a precursor that would be fairly typical of precursors deposited by more scalable techniques. Precursors were made both by the stacked elemental layer approach, where one element at a time wsas evaporated, as well as by a co-evaporation method. Adhesion problems limited device performance, and the co-evaporated precursors displayed unintended segregation of Cu and I in a direction normal to the film plane. The best cell efficiency was 3.5%.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes work exploring a new technique for the formation of Culn(subscript x)Ga{sub 1-x}Se2 thin films. The cu deposition was separated fro the Ga+In deposition such that precursor films with compositions of either Cu(subscript x)Se or (In(subscript x)Ga{sub 1-x})2Se3 were formed. These precursors were exposed to either (a) In+Ga+Se or (b) cu+Se at substrate temperatures> 500 C to form Galn(subscript x)Ga{sub 1-x}Se2. Films made from the Cu(subscript x)Se precursors were unexceptional, but films made from the (In(subscript x)Ga{sub 1-x})2Se3 precursors were of exceptional smoothness and density. During the period covered in this report, a device made fro one of these films resulted in what, at the time, was the highest total-area efficiency measured for any non-single-crystal, thin-film solar cell, at 15.9%.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes research in Rapid Thermal Processing (RTP), a process that allows the formation of CuInSe2 without the use of H2Se. RTP is a well-established method of rapidly achieving temperatures necessary to melt and recrystallize materials such as Si and and silicides. RTP processes can rapidly and uniformly heat large surface areas to hundreds of degrees Celsius. RTP is the most promising method of rapid recrystallization studied to date, being readily scalable from the research to the production level. The approach to the experiment was divided into two sections: (1) fabricating the precursor film and (2) processing the precursor film. The objective of the first phase of the work was to fabricate the thin films by RTP, then fully characterize them, to demonstrate the viability of the process as a method by which to make device-quality CuInSe2. The second phase was to demonstrate that material made by this method could be used to make an active photovoltaic device. 24 refs.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a highly practical treatment of Glancing Angle Deposition (GLAD), a thin film fabrication technology optimized to produce precise nanostructures from a wide range of materials. GLAD provides an elegant method for fabricating arrays of nanoscale helices, chevrons, columns, and other porous thin film architectures using physical vapour deposition processes such as sputtering or evaporation. The book gathers existing procedures, methodologies, and experimental designs into a single, cohesive volume which will be useful both as a ready reference for those in the field and as a definitive guide for those entering it. It covers: Development and description of GLAD techniques for nanostructuring thin films Properties and characterization of nanohelices, nanoposts, and other porous films Design and engineering of optical GLAD films including fabrication and testing, and chiral films Post-deposition processing and integration to optimize film behaviour and structure Deposition systems and requirements for GLAD fabrication A patent survey, extensive relevant literature, and a survey of GLAD's wide range of material properties and diverse applications.

Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Materials Science and Technology, Volume 24: Preparation and Properties of Thin Films covers the progress made in the preparation of thin films and the corresponding study of their properties. The book discusses the preparation and property correlations in thin film; the variation of microstructure of thin films; and the molecular beam epitaxy of superlattices in thin film. The text also describes the epitaxial growth of silicon structures (thermal-, laser-, and electron-beam-induced); the characterization of grain boundaries in bicrystalline thin films; and the mechanical properties of thin films on substrates. The ion beam modification of thin film; the use of thin alloy films for metallization in microelectronic devices; and the fabrication and physical properties of ultrasmall structures are also encompassed. Materials scientists and materials engineers will find the book invaluable.
