abstract: Ternary GaAsP nanowires (NWs) have gained great attention due to their structure-induced novel properties and band
gap that can cover the working wavelength from green to infrared. However, the growth and hence applications of selfcatalyzed
GaAsP NWs are troubled by the difficulties in controlling P and the complexities in growing ternary NWs. In
this work, self-catalyzed core-shell GaAsP NWs were successfully grown and demonstrated almost stacking-fault-free
zinc blend crystal structure. By using these core-shell GaAsP NWs, single NW solar cells have been fabricated and a
single NW world record efficiency of 10.2% has been achieved. Those NWs also demonstrated their potential
application in water splitting. A wafer-scale solar-to-hydrogen conversion efficiency of 0.5% has been achieved despite
the low surface coverage. These results open up new perspectives for integrating III−V nanowire photovoltaics on a
silicon platform by using self-catalyzed GaAsP core−shell nanowires.
