Today's best perovskite solar cells use a mixture of formamidinium and methylammonium as the monovalent cations. With the addition of inorganic cesium, the resulting triple cation perovskite compositions are thermally more stable, contain less phase impurities and are less sensitive to processing conditions.
Although the best research-cell efficiency (>25%) of perovskite solar cells (PSCs) is comparable with that of silicon solar cells, the industrial application of PSCs is limited by the further improvement of performance and stability.
In particular, we discuss various strategies that have been proposed for increasing the efficiency and stability of perovskite materials and their corresponding solar cells; these include modifying the composition of lead-based and lead-free inorganic perovskites, solvent engineering, deposition techniques, and surface and interfacial passivation.
With the addition of inorganic cesium, the resulting triple cation perovskite compositions are thermally more stable, contain less phase impurities and are less sensitive to processing conditions. This enables more reproducible device performances to reach a stabilized power output of 21.1% and ∼18% after 250 hours under operational conditions.
We have reviewed the recent progress in CsPbX 3 and Pb-free CsSnX 3 inorganic perovskite-based solar cells, which have shown promising optoelectrical and thermodynamic properties. The PCE values from the studies discussed here are compared in Table 1.
