Etch resistant Zn1-xMgxO alloys as an e'-acceptor for dye sensitized solar cells
In DSSCs, dyes are used to photosensitize a nanoporous electrode, most commonly TiO2. Light excites the dye, which then transfers an electron to the metal oxide electrode. The electron then travels to the conducting contact and through the external circuit. An electrolyte surrounding the electrode replenishes the electron deficiency in the dye. Zinc oxide has been explored as an alternative electron acceptor material to TiO2 because of its abundance of easily synthesized nanostructures. However, ZnO suffers from Zn-Dye aggregate formation. The carboxyl groups of the dye are acidic and form ...
