Photoelectrochemical properties of nanomultiple CaFe2O4/ZnFe2O4 pn junction photoelectrodes.
Nanomultiple CaFe2O4/ZnFe2O4pn junctions are prepared by a pulsed laser deposition method to explore their photoelectrochemical properties as the photoelectrodes. It is demonstrated that the multiple-pn-junction structure is favorable to enhancing the photocurrent density and the onset potential of the photoelectrode. Furthermore, the 20-junction photoelectrode-based PEC cell yields a high open...
متن کاملEffect of Annealing Temperature on TiO<sub>2</sub>ZnO CoreShell Aggregate Photoelectrodes of Dye-Sensitized Solar Cells
Photoelectrodes made of submicrometer-sized aggregates of ZnO nanocrystallites coated with TiO2 layer by atomic layer deposition with different annealing temperatures were investigated for dye-sensitized solar cells. Although the annealing at 350 C is commonly used for the ZnO aggregates in order to preserve the desired large surface area and mesoporous structure, the presence of ALD-TiO2 layer...
متن کاملTransparent TiO2 nanotube array photoelectrodes prepared via two-step anodization
Two-step anodization of transparent TiO2 nanotube arrays has been demonstrated with aid of a Nb-doped TiO2 buffer layer deposited between the Ti layer and TCO substrate. Enhanced physical adhesion and electrochemical stability provided by the buffer layer has been found to be important for successful implementation of the two-step anodization process. With the proposed approach, the morphology ...
متن کاملNumerical Simulation of CdS/CIGS Tandem Multi-Junction Solar Cells with AMPS-1D
Numerical modeling of polycrystalline thin-film solar cell serves as an imperative procedure to test the suitability of proposed physical clarification and to anticipate the effect of physical changes on cell performance. All in all, this must be conducted with only partial knowledge of input parameters. In this paper, we evaluated the numerical simulation of CdS/CIGS tandem multi junction sola...
