Carbon based electrode technologies for novel solar cells
Over recent years several innovations have been introduced in order to move from a conventional silicon based photovoltaics to new cheap and efficient solutions. Most of new emerging technologies (i.e., DSCs, organic, perovskites etc.) rely on transparent conductive oxides such as Fluorine Tin Oxide (FTO) or Indium Tin Oxide (ITO) as window electrode, that suffer of high cost, high instability in presence of acid or base, poor transparency in the near infrared region, tendency to ion diffusion into polymer layers and brittleness in flexible substrates. This project, falling within the EPSRC Solar Technology research area, will investigate the use of alternatives solutions such as carbon based materials (i.e., graphene and carbon nanotubes), which show remarkable optical and electrical proprieties and are a promising answer to the need of stable, highly conductive and highly transparent electrodes.
