Special K: The microstructure of K-doped ZnO nanoparticles, and the dynamics of hole transportation and recombination upon their application in p-type dye-sensitized solar cells, are reported. Compared to the widely used benchmark material NiO, p-DSCs based on K-doped ZnO shows higher absorbed-photon-to-electron conversion efficiencies in the visible range. The transparency and fast hole diffusion are attractive properties for use in p-DSCs.
