Article Synopsis
  • Chalcopyrite CuInSe (CISe)-based thin-film solar cells have gained attention since the 1970s, with established technology now leading to commercial products.
  • Despite advancements, there are still many unexplored aspects of the materials science and defect physics in CISe-based films and devices that need further research.
  • The paper reviews critical issues in CISe materials and devices, including Cu-deficient phases, alkali-metal effects, flexible solar minimodules, and open circuit voltage loss analysis.
