  • Fabrication of CuInGaSe₂ thin film solar cells using low-cost air-stable inks

    Creator:
    Wang, Wei
    Abstract:
    CuInGaSe₂ (CIGS), a promising thin film solar cell material, has gained lots of attention in decades due to its high energy conversion efficiency and potential lower manufacture cost over conventional Si solar cells. As a cheaper processing method compared to vacuum-based techniques, solution-based deposition has been successfully applied to fabricate...

  • Growth, Characterizations, and Applications of Patterned Nanostructured Thin Film

    Creator:
    Gao, Zhongwei
    Abstract:
    A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...

  • Investigation of solution-based processes for functional metal oxides : printing, nanostructures, and applications

    Creator:
    Han, Seung-Yeol
    Abstract:
    The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....

  • Solution-based Chalcogenide Thin Film Deposition

    Creator:
    Pan, Changqing
    Abstract:
    As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...

  • Cu-Ga-S/ZnS Quantum Dots with Silica Melting Gel as a Luminescent Downshifting Coating for Enhancing Solar Photovoltaic Power Generation

    Creator:
    Chen, Si-Hao
    Abstract:
    Solar cells, also known as photovoltaic devices, are a class of renewable energy systems that can convert photons into electrons without the carbon dioxide emission. Short-wavelength, high-energy photons in the ultraviolet (UV) range can't be efficiently utilized by most solar cells because of the spectral mismatch. Luminescent downshifting is a...

  • Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

    Creator:
    Jin, Hyung Dae
    Abstract:
    Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...

  • Development of solution-based reaction processes for micro- and nano-structured semiconductors

    Creator:
    Lee, Doo-Hyoung
    Abstract:
    The focus of this study is to develop a general and low-cost solution-based process to fabricate micro- and nano-structured semiconductors that are suitable for electronics. This process uses simple metal halide precursors dissolved in a solvent (organic or aqueous) and is capable of forming uniform and continuous thin films via...

  • Nanotechnology for solar module applications : zinc oxide nanostructures and anti-reflective coating modeling, deposition, analysis, and model fitting

    Creator:
    Han, Katherine M.
    Abstract:
    To become a competitor for fossil fuels such as coal, solar installations will need to be produced and installed at a price equal to or below grid parity. This price can be approached by either reducing the overall system cost or increasing system efficiency. The focus of this paper is...
