HEMP 2016: Hot Electrons and Solar Energy

Date: 15th-16th September

Location: Lecture Theatre G41, Royal School of Mines, Imperial College London, Prince Consort Road, South Kensington

Maps and travel information can be found on the Imperial College campus information page


The High Efficiency Materials for Photovoltaics (HEMP) workshop is held annually at Imperial College London and each year tackles a different aspect of photovoltaic device development.  In 2016 the workshop will address the opportunity for hot electron effects in solar cells and optoelectronic devices. 

Attendance is free but we ask that delegates register their interest in advance. To register your interest in attending the workshop please fill out the form here

Please Note: Registration for attending the evening reception on the 15th of september is now CLOSED.
