Semi Transparent Organic Solar Cells.

Key Information

Supervisors: Dr C Tsoi Dr T Watson.

Expected Interview Date: 17th June 2019.

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.
  • Solution processable thick layer top semi-transparent electrode with high conductivity and transmission.
  • 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.

Swansea University is a top 30 UK institution for research excellence (Research Excellence Framework 2014) and has been named Welsh University of the Year 2017 by The Times and Sunday Times Good University Guide.

The Materials and Manufacturing Academy (M2A) in the College of Engineering is a Swansea University initiative which provides postgraduate research training in partnership with industry; providing access to world-class laboratories and a wealth of academic and industry expertise. The M2A is committed to delivering high quality collaborative research opportunities within an inclusive environment, funded by the Welsh European Funding Office (WEFO), the Engineering and Physical Sciences Research Council (EPSRC), Swansea University and Industry partners. 

Interwoven through the research study are business, technical and entrepreneurial courses, designed to support and prepare participants for a senior role in industry or academia, on completion of their studies. Research Engineers may participate in our career mentoring system, offering opportunities to engage with M2A alumni and other senior staff from across the University. 

The Athena SWAN charter recognises work undertaken by institutions to advance gender equality. The College of Engineering is an Athena SWAN bronze award holder and is committed to addressing unequal gender representation.

Applications from women are particularly welcomed. As a positive action to address gender imbalance, female undergraduates considering a career in research are invited to join our two-day laboratory taster session and learn about a typical day in the life of a research engineer.
