Description of the organisation

Imperial College London (ICL) is a science, engineering and medicine-based university with 13,000 students and 6,000 staff, and is consistently ranked in the global top 20 universities. Energy is one of the College’s key strategic themes for growth, with OPV an important component in the energy research portfolio. The College has made significant recent investments to create one of the largest global research efforts in the field of organic electronics, encompassing some 25 academics and about 150 pre- and post-doctoral researchers across the departments of Physics, Chemistry and Materials.
The current Centre for Plastic Electronics (CPE) research activities, financially supported by the College, occupy recently substantially refurbished and well-equipped laboratory space in Physics/Chemistry/Materials and have access to two state of the art clean rooms. The chemistry capability includes a synthetic laboratory area with over 20 recently refurbished fume hoods, flow chemistry, and equipped with small molecule and polymer characterisation equipment, controlled environment device fabrication and testing. Specialist equipment for semiconductor optical and electrical characterisation is in place, including: temporally/spectrally/spatially resolved fluorescence, fluorescence quantum efficiency, µs-ms transient absorption spectroscopy (TAS), time-of-flight transient photocurrent and dark injection current measurements, transient photovoltage, photocurrent and charge extraction analyses, electroabsorption, spectroscopic ellipsometry, high resolution confocal Raman spectroscopy, transistor characteristics measurement, optical and electrical testing of solar cells and photodetectors, Kelvin probe, four point conductivity, impedance analysis, etc.

Role in the Project

In the CHEETAH program IMPERIAL will take part in R&D activities on organic PV, and in the CSA activities.
The applicants groups have extensive experience in the fabrication and characterisation of OPV devices, including efficiency, stability and life cycle analyses. We have particular expertise in evaluating mechanisms of degradation.


Key people involved

James Durrant, Professor of Photochemistry, is a leader in photochemical approaches to solar energy conversion and molecular solar cells (> 250 research papers, h-index of 70).
