Photovoltaic properties. (a) J(V) characteristics of the as-grown and annealed ZnO/CdTe core-shell NW arrays at 300°C and 450°C for 1 h, under dark conditions (dashed lines) and AM 1.5G standard illumination conditions (solid lines). (b) J(V) characteristics of annealed ZnO/CdTe core-shell NW arrays at 450°C for 1 h under dark conditions (dashed line) and AM 1.5G standard illumination conditions (solid lines). The illumination is performed for a varying time (i.e., light-soaking effects).
