Transparent graphene conducting films are successfully incorporated in thin‐film CdTe solar cells as the front electrode. A four‐layer graphene film, deposited by an ambient pressure chemical vapor deposition (CVD) method, possesses a carrier mobility of 550 cm 2 V −1 s −1 and an optical transparency of 90.5% from 350–2200 nm, achieving an overall efficiency of 4.17% in the prototype device.
