Electronic and Photonic Molecular Materials Group

Photovoltaic devices built using organic components.

The Electronic and Photonic Molecular Materials (EPMM) group is based in the Department of Physics and Astronomy at the University of Sheffield. We have a long-standing interest in many aspects of the physics and technology of solution processable semiconductors and optoelectronic devices. Current research programmes includes detailed study into perovskite and organic photovoltaic devices, organic field-effect transistors and organic and hybrid-semiconductor photonic devices.

Our work is conducted in a series of laboratories and clean rooms, allowing us to undertake materials synthesis, device preparation and evaluation. Micro- and nano-scale devices and structures are also fabricated in the Nanoscience Clean Rooms at Sheffield North Campus. We have access to a range of spectroscopic techniques for basic material science, including ultra-fast lasers and a range of scanning probe and electron microscopes. We make regular use of large experimental facilities including the Diamond Light Source to explore the nanostructure of the materials we create.
