| Description | We found out that it was very difficult to make a bock-copolymer material that phase-separated and also worked well as a photovoltaic semiconductor. The challenges were significant and these resulted from having to design differing electronic functionality into the different blocks for charge separation, with the different blocks also phase-separating on the right length-scale to create percolation paths. Basically, the work told us that this was a difficult route to create a PV material, and that it was much easier to work with separate components (polymers and fullerenes) and then process the films using thermal / solvent techniques to obtain high efficiency. |

| Description | The collaboration proved the business model of Ossila, and the company now continues to grow, employs almost 20 people and will soon be turning over £1M on an annual basis. Ossila was founded in 2009 by organic electronics research scientists with the aim of providing the components, equipment and materials to enable faster and smarter research and discovery. Five years on, and we're proud to supply our products to over 600 different institutions in over 57 countries across the world. Having spent many years both in industry and academia developing organic and thin film LEDs, photovoltaics and FETs, we know how long it takes to develop a reliable and efficient device fabrication and testing process. As such, we have developed packages of products and services to enable researchers to jump-start their organic electronics development program. Our research scientists have significant experience in the processing of materials into LEDs, PVs and FETs, and amongst our team of physicists, chemists and engineers we have a huge collection of knowledge on thin film electronics. The vision behind Ossila is to share this experience with both academic and industrial researchers and to make their research more efficient. By providing products and services that take the hard work out of the device fabrication process, and powerful equipment to enable accurate, rapid testing, we can free scientists to focus on what they do best - science. |
