Use of doped oxides for enhanced performance solar cells — •Judith MacManus-Driscoll — Dept. Materials Science, University of Cambridge, U.K.

ZnO and TiO2 are two of the most commonly used n-type metal oxide semiconductors in new generation solar cells due to their abundance, low-cost and stability. ZnO and TiO2 can be used as active layers, photoanodes, buffer layers, transparent conducting oxides, hole-blocking layers and intermediate layers. Doping is essential to tailor the materials properties for each application. The dopants used and their impact in hybrid solar cells and all inorganic solar cells are presented. In addition, the advantages, disadvantages and commercial potential of the various low energy fabrication methods of these oxides are presented.
