In dye-sensitized solar cells (DSC) scattering layers are used to increase the path length of light incident on the TiO2film. This is typically achieved by the deposition of an additional TiO2layer on top of an existing transparent film and designed to trap light. In this work we show that a simple acid pretreatment can lead to the formation of a scattering “skin” on the surface of a single TiO2film performing a similar function to a scattering layer without any additional depositions. This is important in increasing manufacturing throughput for DSCs as further TiO2depositions require additional materials and heat treatment. The pretreatment leads to self-assembly of a scattering layer of TiO2which covers the surface on short-term immersion (<30 min) and penetrates the bulk layer upon longer immersion. The method has been shown to increase the efficiency of the device by 20%.
