Organic photovoltaics

Profile

The OPV group at SDU NanoSYD is doing research and development of next generation flexible organic solar cells including their upscaling from lab to roll-to-roll (R2R) scale. In addition, new work on supercapacitors is done together with the company partner InnoCell Aps. For more information, please see our OPV webpage.

Power conversion efficiency

The OPV group works from a lab-to-fab principle, where lab scale developments are transferred to large scale without modifying the fabrication technology. This is possible through the combined infrastructure of R2R slot-die coating systems, R2R vacuum sputter systems and R2R lamination tools. This also includes integration of efficiency enhancing upconversion layers and nanostructures.

Device lifetime

To minimise the degradation of the cells, we propose the integration of stabilising additives that are specifically designed towards suppressing photooxidative processes that take place in organic solar cells under operation. In addition, interface engineering for improved device stability is another focus area in the group.

Scalability of production

Due to our unique R2R production facility at SDU NanoSYD, the aforementioned solutions can all be transferred from a lab to fab scale, thus targeting low cost printing of efficient and stable OPV modules in a high-speed mass production process.
