Project 1

High K-dielectric oligomers for organic electronic applications-towards ferroelectric semiconducting polymers.

Significant energy losses in organic solar cells are a result of the S1 excited state having strong coulombic binding. Inorganic solar cells, for example silicon, gallium arsenide, perovskite etc., have lower energy losses because of a higher dielectric constant in the materials supports charge separation. It has been proposed that significant advances in organic solar cell device efficiency can be achieved if organic semi-conductors with higher dielectric constants can be synthesised. In this study we look to synthesise high K-dielectric oligomers for analysis, and inclusion in higher organic semiconductors. This is a project in conjunction with Dr Alexander Colsmann (KIT Germany) and the possibility of a joint degree is possible for excellent applicants.


Project 2

Singlet Fission enhanced solar cells- Breaking the Schockley-Quiesser Limit

We have recently demonstrated that discotic liquid crystalline organic semiconductors can be design to promote singlet fission, that is taking the energy of a singlet exciton generated on absorption of a high energy photon to generate two triplet excitons. It has been predicted that we should be able to increase solar cell efficiencies from 32 to 45% power conversion efficiency, or by 40%. I am looking for an excellent student to incorporate these new materials into solar cells. This is a project in conjunction with Dr Alexander Colsmann (KIT Germany) and the possibility of a joint degree is possible for excellent applicants.


Project 3

Discotic liquid crystalline intra-molecular singlet fission materials.

We have recently demonstrated that discotic liquid crystalline organic semiconductors can be design to promote singlet fission, that is taking the energy of a singlet exciton generated on absorption of a high energy photon to generate two triplet excitons. It has been predicted that we should be able to increase solar cell efficiencies from 32 to 45% power conversion efficiency, or by 40%. We would like to know if this is a generic property of discotic liquid crystalline materials and therefore need to complete significant structure property studies. This is an excellent research opportunity for someone interested in the design, synthesise, characterisation and application of advanced organic semiconductors.
