  • An alternative sulfur precursor for chemical bath deposition of CdS thin film 
    Gajanayake, G. K. U. P.; De Silva, D. S. M.; Atapattu, H. Y. R. (Gajanayake, G. K. U. P., De Silva, D. S. M and Atapattu, H. Y. R. (2019). An alternative sulfur precursor for chemical bath deposition of CdS thin film. 4th International Research Symposium on Pure and Applied Sciences, Faculty of Science, University of Kelaniya, Sri Lanka. p98, 2019)
    Solar energy is the most appropriate electrification method for a tropical county like Sri Lanka. At present, Sri Lanka generates more than 72% of its electricity needs at a high cost by burning coal and diesel. To overcome ...
  • Fabrication of FTO/CBD-CdS/ED-CdTe/Cu/Au solar cells and boosting its performance by CdCl2 treatment 
    Gajanayake, G. K. U. P.; Silva, D. S. M. De; Atapattu, H. Y. R.; Lakmal, A. A. I. (Faculty of Science, University of Kelaniya, Sri Lanka, 2021)
    The thin film CdS/CdTe solar cells are promising cost-effective clean energy generating devices against the global energy crisis. Chemical bath deposition (CBD) and electrodeposition (ED) were recognized as being simple ...
  • The influence of substrates on the device performance of the TCO/CBD-CdS/ EDCdTe and TCO/CBD-CdS/CSS-CdTe solar cells 
    Gajanayake, G. K. U. P.; Bandara, K. M. N. S.; De Silva, D. S. M.; Atapattu, H. Y. R. (Faculty of Science, University of Kelaniya Sri Lanka, 2023)
    The development of cost-effective efficient photovoltaic cells is crucial for generating electricity with the most abundant solar energy to eliminate the energy crisis globally. At present, there is a growing interest in ...
  • Introducing an ED-CdTe nucleation layer on the CBD-CdS layer in solar cell fabrication 
    Gajanayake, G. K. U. P.; Silva, D. S. M. D.; Thanihaichelvan, M. (Faculty of Graduate Studies, University of Kelaniya Sri Lanka, 2022)
    Developing a cost-effective and efficient thin-film CdS/CdTe solar is vital in resolving the energy crisis in the world. In the fabrication of solar cells, the weak interlayer contact caused by the voids between the window ...
  • Investigation of electrically insulating and thermally conductive materials for a Peltier module with n-Cu2O and p-Cu2O electrodeposited semiconductors. 
    Gajanayake, G. K. U. P.; Abeywarna, U. K.; Wijesundera, L. B. D. R. P. (International Research Symposium on Pure and Applied Sciences, 2017 Faculty of Science, University of Kelaniya, Sri Lanka., 2017)
    Thermoelectricity is a direct conversion of electrical energy into thermal energy and vice versa. Seebeck effect, Peltier effect and Thomson effect are thermoelectric effects observed for conductors during 1820-1920. After ...
