Intragrain defects
WebA variety of intragrain planar defects are identified and characterized within the SLS-processed amorphous Si films, with sub-grain boundaries being the major intragrain defect (microtwin rich sub-grains are also found to be prevalent within the SLS-processed films). WebApr 11, 2024 · Mixed-organic-cation FA 1−x MA x PbI 3 perovskites are currently attracting intensive attention for their high photovoltaic performance. However, FA 1−x MA x PbI 3 usually has an undesired non-perovskite phase leading to a compromised efficiency, and a facile strategy to achieve pure-phase FA 1−x MA x PbI 3 has been rarely reported. Here, …
