Achieving unprecedented power-output in 4-terminal mirror-symmetrical printable carbon CsPbBr₃ solar cells through dual-solvent engineering

Abstract

Tyndall effect-guided dual-solvent engineering optimized printable carbon-based CsPbBr 3 solar cells, achieving a record PCE of 10.18%. A 4-terminal concentrator enhanced output to 29.44 mW cm −2 , with 93.2% PCE retention after 1000 hours at 150 °C.
