Abstract

Fast air printing of functional oxide films: spatial atomic layer deposition, a new technique with a high potential in the field of low cost photovoltaics.

Highlights

  • A new approach to atomic layer deposition (ALD) has been developed that doesn't require vacuum and is much faster than conventional ALD

  • In our lab we have been using/ developing a novel atmospheric Spatial ALD (SALD) system to fabricate active components for new generation solar cells, showing the potential of this novel technique for the fabrication of high quality materials that can be integrated into devices

  • The burst of nanoscience and nanotechnology in the last decades has brought an associated boom of ALD popularity, since it allows the nanoengineering of surfaces with precise nanoscale control
