Abstract:Solution-processed polycrystalline perovskites (PVKs)
have aroused
tremendous interest in the optoelectronic device field. However, the
inherent high-density defects in the polycrystalline hindered achieving
efficient and stable large-area PVK solar cells (PSCs). Although organic
molecules are already employed to passivate PVK defects, they are
insulating by nature, limiting the carrier transport. Here, we design
an assembly of a small molecule (N,N′-di(propanoic acid)-perylene-3,4,9,10-tetracarboxylic diamid… Show more
