Item Open Access In situ antimony doping of solution-grown ZnO nanorods(Royal Society of Chemistry, 2009-01-01T00:00:00Z) Briscoe, Joe; Gallardo, Diego E.; Dunn, SteveZnO nanorods are doped with Sb during the aqueous chemical synthesis by addition of Sb acetate dissolved in ethylene glycol. The reliable production of p-type ZnO has been a challenge for some time. This is because the as-grown ZnO is nominally n-type due to intrinsic defects, 1 so holes introduced by acceptor dopants are generally compensated by the high intrinsic free electron density. Despite these difficulties, there have been increasing examples in recent years of p-type ZnO thin films and nanostructures. There is significant interest in producing p-type ZnO nanostructures due to many potential device applications. For example, transistors or diodes based on ZnO nano-homojunctions could be used for transparent electronics, UV optoelectronics and photonicItem Open Access Investigation of ZnO nanrod solar cells with layer-by-layer deposited CdTe quantum dot absorbers(Cranfield University, 2011-08-03) Briscoe, Joe; Dunn, S. C.; Dorey, Robert A.Innovation in solar cell design is required to reduce cost and compete with traditional power generation. Current innovative solar technologies include nanostructured dye-sensitised solar cells and polymer solar cells, which both contain organic materials with limited lifetime. This project aims to combine the advantages of ZnO nanorods and quantum dot (QD) absorbers in an all-inorganic solar cell, using the layer-by-layer (LbL) process to increase light absorption in the cell.
