A window of opportunity: A transparent graphene film has been obtained by a new bottom-up chemical approach involving the thermal reaction of synthetic nanographene molecules of giant polycyclic aromatic hydrocarbons which are cross-linked with each other and further fused into larger graphene sheets. Such graphene films have been applied as window electrodes in organic solar cells (see picture).
