Summary on Grant Application Form |
|
The photovoltaic performance of organic materials, including conjugated polymers which display best general electronic peoperties, is limited by enhanced recombination via exicitonic type states. A solution to this problem is to introduce internal heterojunctions using carbon nanoparticles distributed within the polymer. This allows the preferential transfer of one type of carrier into the nanoparticle while leaving the other carrier to be preferentially transported through the polymer. Initially the most suitable carbon nanoparticle/polymer system in which this can be achieved will be studied. This is unknown at present. Particular attention will be paid to the possibility of having separate transport channels for electrons and holes through optimisation of the nanoparticle percolation. It is then aimed to further enhance performance by introducing 'dye sensitisation' at the internal nanojunctions. This would be the first time that this is explored for all organic cells. Indentification of efficient organic dyes and development of methods for their adsorption onto the carbon nanoparticle surface is an unexplored research area.
