Excitonic solar cells (XSCs) are appealing candidates as alternative devices for solar energy conversion, being in principle low cost, rather environmental friendly and suitable for exploiting both diffuse light and the near infrared (NIR) region of solar spectrum.

This lecture focuses on the design and preparation of functional nanomaterials to be applied as photoanodes and cathodes in XSCs, highlighting strategies devoted to improve light managing, charge generation and collection, catalytic performances for electrolyte regeneration.

The use of hybrid networks (exploiting 1D and 2D carbonaceous materials) as efficient photoanodes, as well as the application of oxides alternative to classical nanoparticulate TiO2 (such as ZnO and SnO2) will be discussed. The possibility to apply these processes to synthesize multifunctional materials will be as well outlined.

Particular emphasis will be given to the exploitation of simple, cheap and low environmental impact techniques for material preparation.
