Abstract
Perovskite Mini-Modules In article number 2000473, Nripan Mathews, Subodh Mhaisalkar, Annalisa Bruno, and co-workers demonstrate that perovskite mini-module scaling-up strategies based on the design of the subcell dimensions and geometrical shapes lead to significant improvements of power conversion efficiency (PCE). Optimized thermally co-evaporated perovskite solar modules with 6.4 cm2 active area and geometrical fill factor of ≈ 91% reach a PCE of 18.4% with just 0.7% absolute losses as compared to 40 times smaller perovskite solar cells prepared with the same device structure.
