Commercialisation of emerging technologies requires performance profiles sufficiently high to allow confidence that translation to large scale modules will give commercial performance. For organic solar cells being developed within ACAP key materials’ properties are:

1) high power conversion efficiency (PCE) (>10%);
2) material stability during processing;
3) processability in industrial relevant solvent systems, and
4) new device architectures requiring new materials.

For organic solar cells it is expected that efficiencies for printed modules of between 8 and 10% PCE would provide a commercial performance. Therefore, laboratory-based devices with an efficiency of >10% PCE will be required.

Research is focused on the development of high performance p- and n-type organic semiconductor materials, triplet host materials, understanding degradation mechanisms in OPV devices, block copolymers for solvent compatibility and new materials for luminescent solar concentrators.

In this package one key materials’ property required for commercialisation will be examined, the processability in industrial relevant solvent systems.

Research is focused on the development of block copolymers for compatibility with industrially relevant solvents, and conjugated polyelectrolytes (CPEs) as interface modifiers.
