Wednesday 30 May 2018: Nanostructured metal window electrodes for emerging thin film photovoltaics
Dr Ross Hatton - University of Warwick
Physics 7th floor SCR 12:30-13:30
Emerging thin film photovoltaics (including those based on organic and perovskite semiconductors) processed at low temperature onto flexible substrates, offer a path to a dramatic reduction in the environmental and monetary cost of manufacturing photovoltaics (PVs), and an expansion in the range of applications beyond those available to today’s flat plate PVs. However, this can only be achieved if the window electrode that couples light into these devices is very low cost and compatible with flexible substrates, which rules out the use of conventional conducting oxide electrodes. This talk will describe progress in the development of metal film electrodes less than 100 atoms thick, and discuss their potential use as the window electrode in emerging PVs. In particular the talk will focus on the fabrication, passivation and patterning of films of Ag and Cu, and will be pitched at a general physical science audience.
