WebMar 1, 2024 · As the PVSK thin films are grown by low temperature solution processes, the formation of polycrystalline films with grain boundaries (GBs) is inevitable. As a result, the structural disorders at GBs potentially can form defect states, which possibly degrade the optoelectronic quality of the PVSK films. 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

WebAug 27, 2024 · Advanced Energy Materials. Grain boundaries (GBs) play an important role in most polycrystalline solar cells. In perovskite solar cells, the research community is just starting to understand their effects on performance and long‐term durability. In this essay, three important questions are explored: Do GBs affect: 1) recombination and thus ... WebJul 31, 2024 · Passivating the grain boundary (GB) defects of polycrystalline perovskite films via fused-ring non-fullerene Lewis base deactivators is an effective approach to fabricate high-efficiency and high-stability perovskite solar cells (PSCs). We first introduced the sulfonyl group (O S O) to substitute the carbonyl group (C O) group of fused-ring non …
WebGrain boundaries interact with each other during ingot growth by the generation and annihilation processes and the number of each type of grain boundary changes with the ingot height. The generation processes increase the total number of grain boundaries and the annihilation processes decrease it.
