Currently, transparent conducting oxides (TCOs) are widely used as transparent conductors for thin film solar cells. Because of the potential of roll-to-roll, large-area processing on flexible low-cost substrates, flexible solar cells are a very attractive technology for the low-cost photovoltaic market. For flexible solar cells, an additional requirement for the transparent electrode is that the deposition must be carried out at temperatures lower than the deformation temperature of flexible polymer substrates. In this work we demonstrated that amorphous Cd1-xGaxO1+d alloy films with 0.3<x<0.4 syntehsize at room temperature have favorable optoelectronic properties as transparent conductors on flexible and/or organic substrates while their band edges and electrical conductivity can also be manipulated for transparent thin film transistors as well as electron transport layers.
