Semi-transparent Organic Solar Cells

Lead Research Organisation: Swansea University
Department Name: School of Engineering

Abstract

Organic Solar Cells can be fabricated by solution process which is low cost and enables high throughput sheet-to-sheet and roll-to-roll manufacturing.

Power conversion efficiency for single junction cell of >15% has recently been achieved along with >17% efficiency for a tandem cell.

Significantly, Organic Solar cells have a unique potential as semi-transparent solar cells, as their colour can be tuned according to need.

Semi-transparent organic solar cells have achieved an efficiency of 10% and an average visible transmission of around 40%.

Further research is needed before the technology can be commercialised. Many semi-transparent organic solar cells use evaporated semi-transparent silver electrode, which does not suit high throughput manufacturing processes. In addition, most high efficiency organic solar cells require thin photovoltaic film, a thin electron transporting layer and a thin hole transporting layer (some of the transporting layers also require deposition by evaporation). Hence scalability is currently limited.

The Research Engineer will:
- Develop high efficiency semi-transparent organic solar cells with tunable colour.
- Develop solution processable thick layer top semi-transparent electrode with high conductivity and transmission.
- Develop all solution processable thick layers devices with decent efficiency and transparency, and demonstration of 5 cm x 5 cm scalable semi-transparent organic solar cells.
- Work collaboratively with related research teams in College of Engineering and College of Science.
