<<They also need to improve the conductivity of their film: indium tin oxide is still hundreds of times more conductive. Organic solar cells with indium tin oxide electrodes are between 3 percent and 5 percent efficient. "With graphene thin-film electrodes, we get 0.1 percent," Chhowalla says, "but these are proof-of-concept devices and of course will improve with time.">>
