WebPolycrystalline perovskite solar cells show high power conversion efficiencies despite the presence of grain boundaries (GBs). The benign nature of GBs on the electronic properties and structural stability in metal-halide perovskites contradicts their propensity for point defect formation, a controversy that is far from being understood. WebJan 29, 2024 · Materials scientists have long recognized that grain boundaries (GBs) can be treated as interfacial phases that are thermodynamically two-dimensional (2-D). [ 12, 13] In 1968, Hart first proposed to treat GBs as 2-D interfacial phases.
