Objective The urgent need to reduce carbon emissions in order to mitigate climate change requires the development of clean, renewable energy sources. Solar power offers a virtually unlimited supply of energy, providing it can be harnessed efficiently. Traditional silicon solar cells demonstrate high performance (~20%) but their required method of manufacture prohibits large area production rendering them too expensive to be used on a global scale. Organic solar cells (made from conjugated polymers and fullerenes) have the potential to be fabricated by low cost printing methods allowing for large scale modules to be produced cheaply. Conventional organic solar cells function by generating charge from a singlet excited state. In order to achieve optimum performance the precise morphology of polymer and fullerene must be controlled which can be extremely challenging. These devices however, have attained good efficiencies (10%) but are hampered by severe loss mechanisms which generally involve the formation of a lower energy triplet excited state. We propose to develop novel materials for organic solar cells which will instead utilise this triplet excited state to generate charges. This will enable us to not only eliminate this loss mechanism but due to the unique properties of the triplet excited state will allow for numerous benefits. Firstly, the long lifetime of the triplet excited state will be exploited to allow for a simpler organic solar cell where precise morphological control is not required. Secondly, the proposed new materials will allow for the utilisation of near-IR light which is typically wasted in ALL current solar cell devices. Thirdly, exploiting a unique photophysical process we will produce materials capable of delivering efficiencies in excess of the theoretical limit available to conventional solar cells. Thus we propose that utilisation of triplet excitons is the required step-change to allow for organic solar cells to achieve their ultimate efficiencies Fields of science engineering and technologyenvironmental engineeringenergy and fuelsrenewable energynatural scienceschemical sciencespolymer sciencesnatural sciencesphysical scienceselectromagnetism and electronicssemiconductivitynatural scienceschemical sciencesinorganic chemistrymetalloidsnatural sciencesearth and related environmental sciencesatmospheric sciencesclimatologyclimatic changes Programme(s) H2020-EU.1.1. - EXCELLENT SCIENCE - European Research Council (ERC) Main Programme Topic(s) ERC-StG-2015 - ERC Starting Grant Call for proposal ERC-2015-STG See other projects for this call Funding Scheme ERC-STG - Starting Grant Host institution THE CHANCELLOR MASTERS AND SCHOLARS OF THE UNIVERSITY OF CAMBRIDGE Net EU contribution € 789 041,13 Address TRINITY LANE THE OLD SCHOOLS CB2 1TN Cambridge United Kingdom See on map Region East of England East Anglia Cambridgeshire CC Activity type Higher or Secondary Education Establishments Links Contact the organisation Opens in new window Website Opens in new window Participation in EU R&I programmes Opens in new window HORIZON collaboration network Opens in new window Total cost € 789 041,13 Beneficiaries (2) Sort alphabetically Sort by Net EU contribution Expand all Collapse all THE CHANCELLOR MASTERS AND SCHOLARS OF THE UNIVERSITY OF CAMBRIDGE United Kingdom Net EU contribution € 789 041,13 Address TRINITY LANE THE OLD SCHOOLS CB2 1TN Cambridge See on map Region East of England East Anglia Cambridgeshire CC Activity type Higher or Secondary Education Establishments Links Contact the organisation Opens in new window Website Opens in new window Participation in EU R&I programmes Opens in new window HORIZON collaboration network Opens in new window Total cost € 789 041,13 UNIVERSITY COLLEGE LONDON United Kingdom Net EU contribution € 236 958,13 Address GOWER STREET WC1E 6BT London See on map Region London Inner London — West Camden and City of London Activity type Higher or Secondary Education Establishments Links Contact the organisation Opens in new window Website Opens in new window Participation in EU R&I programmes Opens in new window HORIZON collaboration network Opens in new window Total cost € 236 958,13
