Dr. Charles Ahamefula Ubani, National University of Malaysia, Malaysia 


Research Area:

Solid state energetic materials such as quantum dot, perovskite and wide bandgap nanomaterials such ZnO


Research Experience:

Goal driven research scientist with interest in high quality project delivering high impact scientific outcome and

contributing to teaching content. He is a Ph.D graduate (Physics) of National University of Malaysia (UKM) and a holder of Master Degree in Energy Technology (UKM). Experience in developing novel processing techniques for solid state energetic materials such as quantum dot, perovskite and wide bandgap nanomaterials such ZnO. Reproducible techniques such as organometallic injection method, hydrothermal autoclave, coprecipitation method, spin coating, screen printing, spray pyrolysis and thermal evaporation has been successful modified and complementarily used to produce energetic products for optoelectronic devices.
Precise control of the thermodynamic condition of the reactants has been achieved at low temperature condition and the processing technique produced high quality monodispersed QDs capable of absorbing wide spectral wavelength. The research products has been presented in indexed conferences and published in high quality journals such as Energy Procedia, Advanced Materials Journal and proceedings of Material Today. Recent innovation in “development prototype non-toxic semiconductor quantum dot sensitized solar cell” provided depth of insight on materials response to adverse conditions relative to their performance in device.
Among the processing techniques that have been modified include organometallic injection method, hydrothermal autoclave, spray pyrolysis and thermal evaporation which have been successfully used to process CdSe QDs, PbSe QDs and to develop a quaternary QDs based on CuInS 2 (CuInS 2 , CuInZnS 2 , CuInGaS 2 , ZnS-CuInGaS 2 ); hydrothermal autoclave, coprecipitation method has been modified and used to process ZnO while spin coating and screen printing were used to fabricate low-cost solar cell device.
