Fabrication of Dye Sensitized Solar Cells Using Native and Non-Native Nanocrystals in Ferritin as the Dye
Recent studies have demonstrated the potential of different nanocrystals synthesized in ferritin to act as light harvesters for high efficiency solar cells. This study investigates the possibility of using these nanocrystals as alternative dyes for dye-sensitized solar cells. Four different dye-sensitized solar cells were successfully fabricated using iron, cobalt, manganese and lead-sulfide nanocrystals within ferritin as the dye. The efficiency obtained were respectively 0.06 %, 0.14%, 0.25%, and 0.26%. These results show that ferritin minerals can indeed act as solar harvesting substrates, and helped us understand how this technology would need to be investigated further in order to make them more practical and efficient.
