  1. Fundamental Investigations of Surface and Subsurface Damage, and Wear in Diamond Wire Sawing of Silicon

    29 May 2019 | Contributor(s):: Kumar, Arkadeep

    Advisors: Shreyes N. Melkote, Steven Danyluk, Richard W. Neu, Christopher Saldana, Chris ArconaAn impediment to widespread adoption of photovoltaics is the high cost of solar cells, which use mono- or multi-crystalline silicon wafers as substrates. The wafers are cut from silicon ingots using the...

  2. Measurement and Analysis of Wire Sawing Induced Residual Stress in Photovoltaic Silicon Wafers

    27 May 2016 | Contributor(s):: Pogue, Vanessa Ann

    Advisors: Shreyes N. Melkote, Steven S. Danyluk, Ajeet RohatgiThe manufacturing process of a photovoltaic Si wafer comprises of first a high temperature heating process to produce a Si ingot from polycrystalline Silicon, which is then cut into bricks and subsequently sawn into wafers using a wire...

  3. Development of Oxidation Resistant Molybdenum-Silicon-Boron Composites

    07 Jan 2016 | Contributor(s):: Marshall, Peter

    Advisors: Joe Cochran, Thomas Sanders, Arun Gokhale, Robert Speyer, David L. McDowell, Richard NeuThe development of molybdenum - silicon - boron (Mo-Si-B) composites having a combination of high temperature strength, creep, and oxidation residence has the potential to substantially increase the...

  4. Development of Low-Cost and High-Efficiency Commercial Size N-Type Silicon Solar Cells

    21 Sep 2015 | Contributor(s):: Ryu, Kyung Sun

    Advisors: Ajeet Rohatgi, Gee-Kung Chang, Thomas K. Gaylord, Shreyes N. Melkote, Miroslav M. BegovicThe objective of the research in this thesis was to develop high-efficiency n-type silicon solar cells at low-cost to reach grid parity. This was accomplished by reducing the electrical and optical...
