Towards a graphene transparent conducting electrode for perovskite/silicon tandem solar cells

In the special issue article 'Towards a graphene transparent conducting electrode for perovskite/silicon tandem solar cells', published in Wiley, the team of researchers from Oxford Materials' Electronic and Interface Materials Laboratory report a novel graphene technique via thin film 'ion-charged dielectrics' compatible with perovskite/silicon solar cells.

By electrostatically doping graphene monolayers, they show a reduction of >60% in sheet resistance, with light transmittance through the graphene being entirely unaffected.

The researchers' model of perovskite tandem efficiency indicates that a doped graphene transparent conducting electrode could enhance cell performance while improving the sustainability of future solar energy devices.
