Existing partnership projects

Indium replacement – Queen Mary University, London

Indium is used mainly in Indium Tin Oxide (ITO) which is applied widely in solar panels, mobile phones, television screens and computers. It is on the EU Critical Materials List, and over two-thirds of the world’s scarce reserves are in China. At a current price of £360/kg, global demand for Indium is £2.6bn/year and rising.

Queen Mary University, London is collaborating with Paragraf and performing basic graphene research to study and develop a wide range of graphene devices. Paragraf “next-generation” graphene will also be assessed by the University as a potential ITO replacement for organic LEDs. The project is funded by a £500,000 award from Innovate UK.

Solar cell efficiency improvement – Verditek

Traditional solar cells have effectively reached their maximum level of efficiency, at around 23-24%. Improvements of <0.5% are considered highly significant. Performance is constrained by the metal mesh used to disperse current across the cell, and protect it from damage. The shading effect of the mesh prevents around 3% of the surface area from absorbing light.

Depositing optically transparent, highly conductive graphene directly onto the solar cell surface facilitates current dispersal and eliminates shading. In principle, this will improve solar cell efficiency by 3%. Paragraf is working in partnership with Verditek, which is supplying solar cells for graphene deposition. A project to prove the principle has been completed, and a further Joint Development Partnership has now been agreed to advance the technology for the first large-scale graphene silicon solar cell.
