Abstract

We demonstrate the close-spaced sublimation growth of polycrystalline cadmium telluride (CdTe) thin films on a flexible graphene electrode/thin glass substrate structure. Prior to the growth of CdTe films, chemical-vapor-deposited graphene was transferred onto a flexible glass substrate and subjected to electron-beam irradiation at an energy of 0.2 MeV in order to intentionally introduce the defects into it in a controlled manner. Micro-Raman spectroscopy and sheet resistance measurements were employed to monitor the damage and disorder in the electron-beam irradiated graphene layers. The morphology and optical properties of the CdTe thin films deposited on a graphene/flexible glass substrate were systematically characterized. The integration of the defective graphene layers with a flexible glass substrate can be a useful platform to grow various thin-film structures for flexible electronic and optoelectronic devices.

Chemical bath deposition of cadmium sulfide on graphene-coated flexible glass substrate

Journal Article Seo, Won-Oh; Jung, Younghun; Kim, Jihyun; ... - Applied Physics Letters

We demonstrate a flexible structure of cadmium sulfide (CdS) on graphene-coated glass substrate, where CdS was deposited by the chemical bath deposition method on defective tri-layer graphene. The defects in graphene, confirmed by micro-Raman spectroscopy, were created by a ultra-violet treatment with varying exposure time from 10 to 60 min. The number of defect sites in the graphene as a seed layer was related to the quality of the CdS thin films determined from the results from X-ray diffraction, optical transmittance, scanning electron microscopy, and room temperature micro-photoluminescence. Our film-on-substrate structure of CdS-graphene-on-glass was maintained up to a tensile strain ofmore »« less

Recovery Act : Near-Single-Crystalline Photovoltaic Thin Films on Polycrystalline, Flexible Substrates

Technical Report Selvamanickam, Venkat; Freundlich, Alex

III-V photovoltaics have exhibited efficiencies above 40%, but have found only a limited use because of the high cost of single crystal substrates. At the other end of the spectrum, polycrystalline and amorphous thin film solar cells offer the advantage of low-cost fabrication, but have not yielded high efficiencies. Our program is based on single-crystalline-like thin film photovoltaics on polycrystalline substrates using biaxially-textured templates made by Ion Beam-Assisted Deposition (IBAD). MgO templates made by IBAD on flexible metal substrate have been successfully used for epitaxial growth of germanium films. In spite of a 4.5% lattice mismatch, heteroepitaxial growth of Gemore »« less

High-efficiency cadmium and zinc telluride based thin-film solar cells: Annual report, June 1, 1987--May 31, 1988

Technical Report Rohatgi, A.; Summers, C.; Erbil, A.; ...

This report contains results of research on high-efficiency cadmium and zinc telluride based thin-film solar cells from June 1987 to May 1988. CdTe and CdZnTe and CdTe and CdMnTe films were grown on CdS/SnO/sub 2//glass substrates by molecular beam epitaxy and metal-organic chemical vapor deposition, respectively. As-grown films were characterized by x-ray diffraction, surface photovoltage spectroscopy, and infrared, Raman, and Auger electron spectroscopy, among others, for composition, bulk uniformity, thickness, and film and interface quality. Single-crystal films were grown simultaneously to understand the growth conditions of the polycrystalline films. Cell efficiencies ranging from 6.0% to 6.7% were achieved with themore »« less

High efficiency thin film cadmium telluride solar cells

Conference Chu, T; Chu, S; Britt, J; ... - AIP Conference Proceedings (American Institute of Physics); (United States)

Cadmium sulfide (CdS), grown from an aqueous solution, and zinc oxide (ZnO), cadmium zinc sulfide (Cd[sub 1[minus][ital x]]Zn[sub [ital x]]S), and zinc selenide (ZnSe), deposited by metalorganic chemical vapor deposition (MOCVD), have been used as the window for thin film cadmium telluride (CdTe) solar cells. Thin film solar cells were prepared by the successive deposition of the window and [ital p]-CdTe (by MOCVD and close-spaced sublimation, CSS) on SnO[sub 2]:F/glass substrates. CdS/CdTe(CSS) solar cells show considerably better characteristics than CdS/CdTe(MOCVD) solar cells because of the better microstructure of CSS CdTe films. Total area conversion efficiency of 14.6%, verified by themore »« less
