Cspbi3 tolerance factor
Webt -- Goldschmidt tolerance factor. In an ideal cubic perovskite crystalline structure the A-site and B-site cations optimize their equilibrium bond distances to the oxygen elements without inducing any distortion of the unit cell at t = 1. When 0.78 < t < 1.05, a distorted perovskite structure can normally be stabilized. WebSep 16, 2024 · Inorganic CsPbI3 perovskite holds great promise to prepare high-performance and long-term operational perovskite solar cells (PSCs) because of its ideal band gap and intrinsic superb stability. However, due to the low tolerance factor, the photoactive CsPbI3 perovskite is a high-temperature (330 °C) phase th
