In the aim to realize high performance semitransparent fully coated organic solar cells, printable electrode buffer layers and top electrodes are two important key technologies. An ideal ink for preparation of layer printed should have good wettability negligible solvent corrosion underlying layer.

Abstract At present, the dominating electron transport material (ETL) and hole (HTL) used in state‐of‐the‐art perovskite solar cells (PSCs) are tin oxide 2,2′,7,7′‐tetrakis(N,N‐di‐p‐methoxyphenyl‐amine)‐9,9′‐spirobifluorene (Spiro‐OMeTAD). However, surface hydroxyl groups of SnO 2 layer Li + ions within Spiro‐OMeTAD HTL generally cause charge recombination migration, significantly reducing devices' performance stability.

We have demonstrated in this article that both power conversion efficiency (PCE) and performance stability of inverted planar heterojunction perovskite solar cells can be improved by using a ZnO:PFN nanocomposite (PFN: poly[(9,9-bis(3'-(N,N-dimethylamion)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctyl)-fluorene]) as the cathode buffer layer (CBL). This could form compact defect-less CBL film on perovskite/PC61BM surface (PC61BM: phenyl-C61-butyric acid methyl ester). In addition, high...
