Abstract

original image

Layering in the sun: Layered graphene and quantum dot (QD) films can be fabricated simply on transparent conducting indium tin oxide (ITO) substrates from aqueous solutions. The structure and favorable work function of graphene make it effective for the collection and transfer of photogenerated charges to the electrode, resulting in a high-performance photovoltaic device (see picture; IPCE=incident photon-to-charge-carrier conversion efficiency, SWNT=single-walled carbon nanotube).
