Thermodynamically stabilized β-CsPbI 3 –based perovskite solar cells with efficiencies >18%

Tetragonal phases for perovskite solar cells The power conversion efficiencies (PCEs) of all-inorganic perovskites are lower than those of materials with organic cations. This is in part because these materials have larger bandgaps. The cubic crystal phases of these materials also exhibit poor stabi... View More
