2. Perovskite solar cell - Wikipedia

   en.wikipedia.org/wiki/Perovskite_solar_cell

   A perovskite solar cell. A perovskite solar cell (PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer.

3. Perovskite (structure) - Wikipedia

   However, the solar cells are prone to degradation due to volatility of the organic [CH 3 NH 3] + I − salt. The all-inorganic perovskite cesium lead iodide perovskite (CsPbI 3) circumvents this problem, but is itself phase-unstable, the low temperature solution methods of which have only been recently developed. [47]

4. Tin-based perovskite solar cell - Wikipedia

   en.wikipedia.org/.../Tin-based_perovskite_solar_cell

   The main obstacle to viable tin perovskite solar cells is the instability of tin's oxidation state Sn 2+, which is easily oxidized to the stabler Sn 4+. [10] In solar cell research, this process is called self-doping, [11] because the Sn 4+ acts as a p-dopant and reduces solar cell efficiency.

5. Ruddlesden-Popper phase - Wikipedia

   en.wikipedia.org/wiki/Ruddlesden-Popper_phase

   Ruddlesden-Popper (RP) phases are a type of perovskite structure that consists of two-dimensional perovskite-like slabs interleaved with cations.The general formula of an RP phase is A n+1 B n X 3n+1, where A and B are cations, X is an anion (e.g., oxygen), and n is the number of octahedral layers in the perovskite-like stack.
