  • Electrochemical deposition of thin film CuGaSe₂ for photovoltaics

    Creator:
    Permanasari, Rina
    Abstract:
    CuGaSe₂/CuInSe₂ tandem junction solar cell is currently being pursued to be a low cost and high efficiency renewable energy source. A reported theoretical efficiency of 33.9% solar cells has been the motivation to fabricate CuGaSe₂ films in a simple and low cost method. Electrodeposition is a potentially suitable method to...

  • A Fabrication Process and Analysis of ZnO-ZnS-Sb₂S3₃ Thin Film Solar Cells

    Creator:
    Catherall, David
    Abstract:
    The purpose of this research is to provide a simple fabrication method for zinc oxide and antimony sulfide based thin film solar cells. Both a ZnO nanorod electron conducting structure and a stibnite absorber show promise in a solar cell. Initial attempts at using only ZnO and Sb2S3, however, resulted...

  • Metal-Organic Framework Thin Films: The Synthesis and The Application

    Creator:
    Zhang, Yujing
    Abstract:
    Metal-organic frameworks (MOFs) have gained increasing attention due to their promising applications (e.g., gas storage/separations, and catalysis) as nanoporous materials stemming from generally ultrahigh porosities and surface areas. Recently, research has shifted to synthesize MOF thin films and micropatterns that enable new applications (e.g., optoelectronics, smart coatings, and sensors). In...

  • Growth, Characterization and Applications of Zinc Sulfide Thin Films by Solution-Based Processes

    Creator:
    Chiu, Dick
    Abstract:
    Zinc Sulfide (ZnS) thin film, with a wide band gap, has been used for many applications, such as buffer layer for CIGS solar cells, light emitting diodes and thin film electroluminescent devices. In this work, ZnS thin films were prepared using two different deposition processes. In the first method, ZnS...

  • Growth, characterizations and applications of copper sulfide thin films by solution-based processes

    Creator:
    Vas-Umnuay, Paravee
    Abstract:
    Copper sulfides (Cu[subscript x]S) are compound semiconductor materials that exhibit considerable optical and electrical properties varying significantly as a function of the composition. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding...

  • A study of ZnS:Mn electroluminescent phosphors grown by halide transport chemical vapor deposition

    Creator:
    Chen, Chia-Jen
    Abstract:
    A low pressure halide transport chemical vapor deposition (HTCVD) system to grow ZnS:Mn electroluminescent phosphors is characterized. Reactor parameters such as gas composition, gas flow rate, and source and substrate temperature are investigated. Crystal structure is investigated using x-ray diffraction, electron spin resonance, and transmission electron microscopy. Chemical characterization includes...

  • Fabrication of ultrathin SiC film using grafted poly(methylsilane)

    Creator:
    Lertwiwattrakul, Wimol
    Abstract:
    β-SiC is a semiconductor for high temperature devices, which exhibits several outstanding properties such as high thermal stability, good chemical stability and wide band gap. There is a possibility of fabricating a crack-free ultrathin SiC film on silicon wafers by pyrolysis of polymethylsilane (PMS) film. This study looks into the...

  • Fabrication of a cadmium sulfide thin film transistor using chemical bath deposition

    Creator:
    Voss, Curtis L.
    Abstract:
    The digital revolution has brought information to every corner of our daily lives. Inexpensive and flexible integrated circuits are needed for this continuing revolution. Silicon technology, the current workhorse of microelectronic industry, is far from inexpensive and flexible. Researchers are taking several different routes to achieve this goal. Amorphous silicon...

  • A multiple solution, laboratory-scale delivery system and its applications

    Creator:
    Gilbuena, Debra M.
    Abstract:
    Researchers around the world use various solution-based deposition techniques to deposit thin films with multiple layers that typically require multiple rounds of deposition. Some such techniques include successive ionic layer adsorption and reaction (SILAR), and layer-by-layer (LBL) deposition. One of the main issues with deposition of these types of films...
