WebThe percentage of high-angle grain boundaries (HAGBs) with misorientations above 15° was below 50%. This result is clearly confirmed in Figure 4d–f showing OIMs taken from a much smaller area, i.e., with a higher resolution. These figures show that low-angle boundaries (LAGBs; marked in red) are more frequent than HAGBs (marked in blue). WebGrain boundary trap passivation in perovskite films has become one of the most effective strategies for suppressing the charge recombination and enhancing the photovoltaic performance of perovskite solar cells, whereas the relevant trap-state properties and the charge carrier dynamics need to be further clar cluthatv
