Tolu completed his undergraduate degree in Engineering Physics at Aberystwyth University, with his masters project involving studying metal-semiconductor interfaces using XPS. He also undertook an industrial placement at ISIS Neutron and Muon source, where he developed instrumentation and software for Muonic atom x-ray spectroscopy.

His current PhD project is about studying ways to create a theoretical solar cell, called a hot carrier solar cell which produces no heat loss. His project involves fabricating new III-V semiconductor heterostructures and constructing devices to probe how charge carriers lose energy in nanostructures using Photoluminescence and Raman spectroscopy. 

PhD supervisors: Louise Hirst (Physics/Materials Science), Prof. Hannah Joyce (Electrical Engineering)

Research topic: Characterisation of hot-carrier effects in ultra-thin solar cells
