GaN nanowires typically exhibit high electron mobility and excellent chemical stability. However, stability of GaN is detrimental for successful attachment of dye molecules and its application in dye-sensitized solar cells (DSSCs). Here we demonstrate DSSCs based on GaN/gallium oxide and GaN/TiO (x) core-shell structures, and we show that coating of GaN nanowires with a TiO (x) shell significantly increases dye adsorption and consequently photovoltaic performance. The best cells exhibited short circuit current density of 1.83 mA/cm(2) and power conversion efficiency of 0.44% under AM 1.5 simulated solar illumination.
