Incorporating thermal co-evaporation in current-matched all-perovskite triple-junction solar cells.

1c allowed us to calculate Urbach energy, 65 a proxy for examining energetic disorder, which showed a decreasing trend from 0.9 (18.4 meV) to 1.5 Å s −1 (17.2 meV) with increasing rate of FAI, whereas the bandgap remained the same at 1.53 eV (Urbach energy fits and Tauc plots can be found in ESI Fig. 6 † ).
