Cost effective – high performance

Unleashing the
power of graphene for solar cells

We have developed and patented a novel process to integrate graphene electrodes into solar cells, replacing the silver and other precious metals whilst retaining or improving power conversion efficiencies and reliability. We are now working with partners to scale this technology and bring the cost and performance benefits to all types of solar cell.

Why We Are here

Over 12% of worldwide silver production is consumed by the solar industry; a figure that is predicted to increase dramatically as we transition to net-zero carbon electricity production. Predictions for silver usage between now and 2050 equate to 85-113% of the known global silver reserves.

Silver and other metals already account for over 10% of the manufacturing cost of a photovoltaic module and contribute to its embedded carbon content.

A lower cost and more sustainable electrode material is urgently required.

New material

A new electrode material is also needed to commercialise the latest generation high-efficiency perovskite solar cells.  Research grade cells use gold electrodes, which are too expensive for volume production.  Other metals cause reliability issues due to metal induced migration.

A single solution

Graphene offers a solution to all of these problems, but only if it can be integrated into the solar cell with sufficient reliability and with a lower resistance than currently available graphene electrodes.

Solve the coming crisis

GraphEnergyTech highly conductive graphene electrodes bring the solution to solve the coming silver crisis in established solar cells technologies and represent an enabling technology for the industrial development of the emerging perovskite solar cells.
