In the late '70s, photocatalysis took a turn when researchers discovered the Ti[O.sub.2] ability to degrade stable organic compounds as they were studying the water photoelectrolysis [1-3].
These devices are photoelectrochemical cells (PECs) [40, 87] with photoactive cathodes consisting of p-type semiconducting materials and include p-type dye-sensitized solar cells (p-DSCs) (Figure 6) [242, 243, 247, 248, 264] and tandem DSCs (t-DSCs) (Figure 7) [265-269] cells of photoelectrolysis for nonfossil fuels production, namely, molecular H2 in the process of water splitting (Figure 8) [270-281] and for carbon dioxide redox reduction (Figure 9) [282-313].
Both of these drawbacks are accounted for in this project.The aim of this project is to optimize the water photoelectrolysis performance of the photoelectrolysis-photovoltaic tandem-cell device by tailoring the microstructure of the thin film hematite photoanods, and up scaling from the laboratory scale to a prototype device.
