Photovoltaics based on nanocrystals, nanowires and their composites have attracted much attention in scientific community as well as industries. This talk will present the achievements in nanowire photovoltaics. The special structures have potential for improved device performance in solar cells due to increased junction area and improved charge carrier collection. The advantages of the nanowire photovoltaics include reduced reflection, light trapping capability, improved band gap tuning, and increased defect tolerance, which are expected to reduce the quantity and quality of material necessary to reach high efficiency and allow for cost reductions. However, low energy conversion efficiencies are often observed in such devices as compared to those with planar structures. Certain challenges have to overcome before high efficiency can be achieved in nanowire photovoltaics.
