Irfan Mahmood Khan

As a PhD candidate specialising in optoelectronic materials, my work focuses on advancing upconversion technologies and hybrid systems integrating inorganic sensitisers with organic emitters for applications in LEDs and solar cells. My doctoral research titled ''Engineering Optoelectronic Inorganic-Organic Interfacial Energy Transfer," explores novel methods to enhance energy transfer processes, particularly triplet-triplet annihilation (TTA), through comprehensive characterisation and fabrication techniques. My approach involves utilizing advanced fabrication methods such as Molecular Beam Epitaxy (MBE) and Spin Coating to develop high-performance photovoltaic devices. Key characterisation techniques include Time-Correlated Single Photon Counting (TCSPC) for photoluminescence (PL) and time-resolved photoluminescence (TRPL), transient absorption (TA), ultraviolet photoelectron spectroscopy (UPS) for band measurement, and Raman spectroscopy.

Prior to my PhD research, I contributed to the synthesis and characterization of thin film photovoltaic devices, including tandem solar cells and dye-sensitized solar cells with composite electrodes.
