Nowadays, the urge for developing high efficiency solar cells has motivated researchers to develop transparent conductive materials (TCMs) beyond their basic properties of high transparency and conductivity. In this work, innovative S:TiO2-FTO nanocomposites with high haze factors (i.e. high ability to scatter light) have been developed using a cheap and facile 2-step process. The morphological, optical, and structural aspects of these nanocomposites will be addressed in detail.

While the total transmittance of these nanocomposites is lowered to slightly below 70%, their sheet resistances are nevertheless significantly decreased by around 30%. By varying the nanoparticle suspension concentrations used to prepare S:TiO2-FTO nanocomposites, the haze factors can be controllably varied from almost 0% up to 55%. An electrode with high haze factor can increase the optical path thus contribute to light absorption finally increase the solar cell efficiency. As a result, the S:TiO2-FTO nanocomposites can be used as promising electrodes in solar cells.
