HEMP 2015

Date: 10th-11th September

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

Co-organised by MultiscaleSolar

  Mutlscalesolar.eu

 

 

 

Supported by the IOP Semiconductor Physics Group and Materials and Characterisation Group.

Maps and travel information are available from the Imperial College campus information page.

The HEMP workshop series started in 2011 and tackles a range of topics associated with high- effi ciency PV research. Each year has a principle topic, but the programme is not exclusive. In previous years HEMP themes have included the intermediate band solar cell, the hot carrier solar cell and the application of nanophotonics in photovoltaics. HEMP 2015 will bring together researchers working on highly mismatched alloys for PV, bridging the gap between materials fabrication and characterisation, device design and theory on a multiscale level. Participants will present the state of the art results in their respective fields and share the difficulties they are facing, spot the missing information that is necessary in order to design efficient solar cells, and establish collaborative activity to achieve the next stage in the development of these materials for photovoltaic devices.

Contact Diego Alonso Álvarez for further information.
