There exists a considerable density of interaggregate grain boundaries (GBs) and intra-aggregate GBs in polycrystalline perovskites. Mitigation of intra-aggregate GBs is equally notable to that of interaggregate GBs as intra-aggregate GBs can also cause detrimental effects on the photovoltaic performances of perovskite solar cells (PSCs).

10 p, 3.9 MB Universal Spin Diffusion Length in Polycrystalline Graphene / Cummings, Aron (Institut Català de Nanociència i Nanotecnologia) ; Dubois, Simon M. M. (Université Catholique de Louvain) ; Charlier, Jean Christophe (Université Catholique de Louvain) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
Graphene grown by chemical vapor deposition (CVD) is the most promising material for industrial-scale applications based on graphene monolayers. It also holds promise for spintronics; despite being polycrystalline, spin transport in CVD graphene has been measured over lengths up to 30 μm, which is on par with the best measurements made in single-crystal graphene. [...]
