  • Effect of CdTe nucleation layer on the performance of CdS/CdTe thin film solar cells 
    Gajanayake, G.K.U.P.; Lakmal, A.A.I.; De Silva, D.S.M.; Dassanayake, B. S. (J Mater Sci, 2023)
    In this study, an electrodeposited CdTe nucleation layer (ED-CdTe*) was introduced on a chemical bath deposited (CBD) CdS layer prior to close-spaced sublimation (CSS) of the CdTe absorber layer to improve the efficiency ...
  • Effect of pH on the morphology of chemical bath deposited ZnO nanowires 
    Jayathilaka, A. P. S. P.; Abeykoon, Y. K.; Dassanayake, B. S.; Dasanayake, N. L. (Faculty of Science, University of Kelaniya Sri Lanka, 2023)
    ZnO is a non-toxic chemical compound that forms nanostructures like nanoparticles, nanowires, nanotubes, and so on. Among these nanostructures, ZnO nanowires have shown the potential for use in applications like light-emitting ...
  • Effect of substrate temperature variation on opto-electronic properties of thermally evaporated CdS thin films 
    Lakmal, A. A. I.; Kumarasinghe, R. K. K. G. R. G.; Maddumage, D. C.; Kumarage, W. G. C.; Munasinghe, M. A. H. M.; Seneviratne, V. A.; Dassanayake, B. S. (4th International Research Symposium on Pure and Applied Sciences, Faculty of Science, University of Kelaniya, Sri Lanka, 2019)
    Cadmium sulfide (CdS) is a II-VI group semiconducting material which has been thoroughly investigated due to its superior optical and electrical properties that can be applicable in wide range of semiconductor devices ...
  • Growth and Characterization of Seed‑Assisted, EDTA‑Treated, Chemical Bath‑Deposited CdS 
    Kumarage, W. G. C.; Wijesundera, R. P.; Seneviratne, V. A.; Jayalath, C. P.; Gunawardhana, N.; Kaur, N.; Comini, E.; Dassanayake, B. S. (Journal of Electronic Materials, 2021)
    A simple low-cost method to enhance the electrical properties including open-circuit voltage (VOC), flat-band potential (Vfb) and short-circuit current (ISC) in the photoelectrochemical (PEC) cell of cadmium sulfide (CdS) ...
  • Investigation of the effect of source temperature on close-spaced sublimated CdTe thin films 
    Lakmal, A. A. I.; Kumarasinghe, R. K. K. G. R. G.; Seneviratne, V. A.; Dassanayake, B. S. (Faculty of Science, University of Kelaniya, Sri Lanka, 2021)
    Cadmium telluride (CdTe) is one of the most promising II-VI group semiconductors used to fabricate heterojunction thin-film solar cells. Close-spaced sublimation is one of the best techniques for the deposition of ...
  • Thermally evaporated copper iodide hole transport layer for CdS/CdTe thin film solar cells 
    Thivakarasarma, T.; Lakmal, A. A. I.; Dassanayake, B. S.; Velauthappillai, D.; Ravirajan, P. (Faculty of Science, University of Kelaniya, Sri Lanka, 2021)
    CdS/CdTe thin-film solar cell is a cost effective and reliable photovoltaic device with reported power conversion efficiencies over 22%. Although large-scale thin-film solar panels with efficiency over 18 % are commercially ...
