Nature Energy, Published online: 11 February 2026; doi:10.1038/s41560-026-01979-x A crystallization strategy enables the successful deposition, through blade-coating under ambient conditions, of phase-pure, wide-bandgap perovskite films with a homogeneous halide distribution. Using this approach, a monolithic perovskite/Cu(In,Ga)Se2 tandem solar cell achieved a power conversion efficiency of 27.3% and exhibited high operational stability.
