We report first results on a new solar cell structure which incorporates n‐type ZnO nanowires, an undoped CdSe layer, obtained from quantum dot precursors, and a p‐type polymer layer as the main components. In the fabrication process the quantum dot layer is converted to a conformal ∼30 nm thick polycrystalline film. The fabrication of the cell occurs in lab air at temperatures below 100 °C. Several intermittent annealing steps raise the energy conversion efficiency to approximately 1%. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
