A nanojunction solar cell consisting of ZnO nanocone tips embedded in a polycrystalline CdTe film is reported. This tip–film structure shows higher conversion efficiency than its planar structure. The higher efficiency is attributable to more efficient charge transport in the nanojunction due to a unique electric field distrobution in the CdTe and the utilization of the small junction area.
