Selective area epitaxial growth of InP nanowire array for solar cell applications

© 2014 IEEE. InP nanowire arrays have been grown and optimized using selective area epitaxy by metalorganic chemical vapour deposition technique. High quality stacking fault free wurtzite nanowires with a wide range of diameters and room temperature minority carrier lifetime as high as ∼ 1.6 ns have been obtained. An axially doped n-i-p structure was further grown and successfully fabricated into solar cell devices. The photovoltaic behaviors of the device have been investigated and compared to simulation results
