Use of Extracted Anthocyanin Derivatives in Nanostructures for Solar Energy Conversion

Gabriele Giancane, Vito Sgobba, and Ludovico Valli 

The critical and predominant rationale in the utilization of the above components is a significant distinction between the photoelectrode and the electrolyte Fermi levels this induces, upon irradiation, a certain potential difference and consequently a measurable current will be supplied by the apparatus. Regarding counter-electrodes, graphite and platinum catalysts can be mentioned.

As reported before, and as widely demonstrated in the literature, the hydroxyl groups ensure anchorage to Ti02 nanoparticles, as in the case of the most popular ruthenium-based dyes [32, 33], 

Theoretical calculations demonstrated that the energy gap between HOMO and LUMO levels is not particularly affected by pH variations, but a systematic downshift is recorded with increasing pH. The energetic levels are not influenced by the substituent, which is usually a glucosidic unit, even though has been widely demonstrated that it increases dye stability [34].
