  • Development of scalable protocols for nanoparticles production. The work includes optimizing synthesis protocols that are compatible with ink formulations. 
  • Development of deposition methods for low-temperature back contacts (e.g. graphene, Ag NWs).
  • Layers characterization using techniques such as UV-vis, electrochemistry, AFM and SEM.
  • Performance tests of final devices (i.e. solar cells).
  • Written weekly reports containing process description, optimal printing conditions and discussion on results and prospects. 
  • As the team is relatively small, everyone is expected to help out with other tasks when possible.
