Organic–inorganic hybrid halide perovskites are widely considered to be one the most
promising material in photovoltaic technology, the use of this semiconductor as absorbent
layer in solar cells has attracted considerable interest due to their excellent properties. It has
been reported that the incorporation of potassium ion is a powerful strategy to tune the
perovskites properties, notwithstanding there has been some disagreement regarding the role
of this monovalent alkali metal within the perovskite structure. Here, we investigated the
impact of K+ on the film properties and photovoltaic performance in double cation perovskite
solar cells Cs 0.1 FA0.9PbI3 . Our results show that K + intervenes in the crystallization process
inducing the extraction of non-reactive PbI2 from the bulk, resulting in a notable
enhancement in morphology and reduced non-radiative recombination. The solar cells
fabricated with 3% of K+ content achieve a PCE of 19.3%, showing a significative
improvement in J sc , Voc and stability values compared with control devices . [-]
