Abstract
Correction for ‘Roadmap and roadblocks for the band gap tunability of metal halide perovskites’ by E. L. Unger et al., J. Mater. Chem. A, 2017, 5, 11401–11409.
The authors regret that for the data set of Csy(MA0.17FA0.83)Pb(Br0.17I0.83)3, erroneous values for the lattice constants a0 were used, causing the data points to deviate from the expected trend in the initial plot of absorption onset vs. pseudo-cubic lattice constant a0. The mistake was noticed when reviewing this data set. The data points indeed fall exactly on the expected trend line and hence present a confirmation rather than deviation from the rule.
This means that the previous statement regarding this data set: “Some of the compounds of the triple-cation (MAyFA1−y)1−zCsz PbI3 alloys (Fig. 2, brown/white square) introduced by Saliba et al. (ref. 3 in the original article) exhibit a similar offset compared to the CsPb(BrxI1−x)3 series suggesting that Cs inclusion on the A-site of the lattice affects the band gap in a comparable manner” was a misinterpretation.
The authors would hereby like to make the following statement:
“The triple-cation alloys (MAyFA1−y)1−zCszPbI3 (Fig. 2, brown/white squares) introduced by Saliba et al. (ref. 3 in the original article) exhibit a similar trend as the data sets of hybrid perovskite materials, suggesting that Cs inclusion on the A-site of the lattice affects the band gap in a comparable manner.”
The authors would like to replace Fig. 2 with the corrected version, shown below.
