Photovoltaic performance of ZnO/CdSe core/shell solar cells. (a) Photocurrent density and voltage characteristic (curve 1) and the power output (curve 2) of the ZnO/CdSe core/shell nanoneedle array-based solar cells under 100 mW/cm2 of simulated AM1.5 spectrum. (b) IPCE spectra of the same solar cell.
