Light-induced water oxidation at silicon electrodes functionalized with a cobalt oxygen-evolving catalyst

Abstract: Integrating a silicon solar cell with a recently developed cobaltbased water-splitting catalyst (Co-Pi) yields a robust, monolithic, photo-assisted anode for the solar fuels process of water splitting to O 2 at neutral pH. Deposition of the Co-Pi catalyst on the Indium Tin Oxide (ITO)-passivated p-side of a np-Si junction enables the majority of the voltage generated by the solar cell to be utilized for driving the water-splitting reaction. Operation under neutral pH conditions fosters enhanced stability of th… Show more

“…That is precisely what he showed to a room full of scientists and engineers at a March 2011 meeting of the American Chemical Society in Anaheim, California. The demonstration doubled as a preview to a 2011 PNAS paper describing his version of an artificial leaf (9). Based on the oxygenevolving complex of leaves, Nocera's device is composed of a slender film the size of a business card that bears crystalline silicon cells covered with a layer of indium tin oxide and containing his catalysts.…”

“…These catalysts model the oxygen-evolving complex of Photosystem II (14) because they: (i) self-assemble under mild conditions (11)(12)(13)15); (ii) exhibit high activity in pH 7-9 water at room temperature (11,12); (iii) are functional in a variety of water sources (12,15); (iv) are comprised of inexpensive, terrestrially abundant materials (11,12); and (v) self-heal by reversing catalyst corrosion at open circuit upon application of a potential (16,17). Their ability to be interfaced easily with light-absorbing and charge-separating materials (18)(19)(20)(21)(22)(23)(24) has permitted the construction of a buried junction PEC device (25,26). In the wireless configuration, the buried junction device captures many of the functional elements of the water-splitting chemistry of a leaf (27,28).…”

“…Recently, cobalt phosphate (CoPi) prepared by an electrodeposition has been reported as an oxygen evolving electrocatalyst (37). Photoelectrochemical properties of Si (37,38) In the present study, we developed a facile fabrication of an efficient BiVO 4 thin film coated on FTO electrode using inorganic salts of bismuth and vanadium. The formation mechanism of the present BiVO 4 thin film electrode was discussed.…”
