• Fundamental optoelectronic and device physics of Cs2NaInI6 double halide perovskites from first-principles to multiscale modeling (2026) · Optical and Quantum Electronics · cited 1× · doi

  Traditional Pb-based PSCs remain limited by issues of toxicity and structural instability. There is a need for environmentally benign, lead-free alternatives. The certified power conversion efficiencies (PCEs) of halide perovskites have surpassed 25% in recent years, but there is still a need for further improvement.
