The use of few-layer graphene membranes as front transparent conductive layer (TCL) is discussed, for both nanostructured thin film solar cells, requiring high temperature processing for the formation of silicon nano-dots in the absorbing layer, and dye sensitized solar cells obtained on glass and on flexible substrates. These applications require the use of a TCL front contact, which is usually made of metal oxides, such as Indium Tin Oxide (ITO), Al-doped ZnO, MgO, F-doped Tin Oxide (FTO)[1]. The use of these materials for high processing temperatures, or for the fabrication of flexible devices, it is an open issue. ITO contact is brittle and it rapidly degrade after bending, so that it is unsuitable for flexible electronics applications. Moreover, the TCL represents one of the most expensive parts of solar cells, and many strategies are under investigation to replace these materials with lower cost but still effective layers.In …
