Implication

Simulation study reveals a 23.5% efficiency in lead-free Cs2AgBiBr6 double perovskite solar cells, highlighting their potential for non-toxic photovoltaic devices.

Key Points

  • Lead-free cs2agbibr6 solar cells reach an efficiency of 23.5% and open-circuit voltage of 1.38 V, demonstrating strong performance with carbon nanotube hole transport layers.
  • Density functional theory calculations evaluate forty device configurations, identifying an optimal 1.654 eV bandgap alongside tailored electron transport layers.
  • Highlights sustainable photovoltaic design by modeling non-toxic double perovskites, while quantum efficiency analyses confirm high charge collection under realistic conditions.
