Transparent Contact Formation
  • Improving the fundamental understanding ‘passivating’ contacts 
    • Importance Fermi-level unpinning
  • Passivating-contact engineering 
    • New buffer layers (better transparency/tunneling trade-off)
    • Minimizing temperature-coefficient solar cells
    • Application to non-Si absorbers
  • Doping-free approaches: --> Aim: Higher contact transparency
  • Solution-processed contacts
    • Road to simple back-contacted solar cells

New Device Architectures
Major aim: improved performance by better temperature tolerance and light management
  • Device polarity and bifaciality
  • Back-contacted heterojunction solar cells
