Efficiency vs. stability in A2GaAgF6 double perovskite solar cells: what convex hull analysis reveals
The most efficient lead-free perovskite solar cell material is also the least stable. That's the headline from running Ouro's prediction routes on a recent paper from Shimul et al. in Scientific Reports (April 2026).
Shimul, Kriaa, Biswas et al. studied four fluoride double perovskites A\u2082GaAgF\u2086 (A = Na, K, Rb, Cs) as lead-free absorber candidates for solar cells. Using DFT (GGA-PBE in CASTEP) plus SCAPS-1D device simulation and Random Forest ML, they report:
