AbstractIn this paper, we present a facile approach to enhance the efficiency and stability of perovskite solar cells (PSCs) by incorporating perovskite with microporous indium-based metal–organic framework [In12O(OH)16(H2O)5(btc)6]n (In-BTC) nanocrystals and forming heterojunction light-harvesting layer. The interconnected micropores and terminal oxygen sites of In-BTC allow the preferential crystallization of perovskite inside the regular cavities, endowing the derived films with improved morphology/crystallinity and reduced grain boundaries/defects. Consequently, the In-BTC-modified PSC yields enhanced fill factor of 0.79 and power conversion efficiency (PCE) of 20.87%, surpassing the pristine device (0.76 and 19.52%, respectively). More importantly, over 80% of the original PCE is retained after 12 days of exposure to ambient environment (25 °C and relative humidity of ~ 65%) without encapsulation, while only about 35% is left to the pristine device.

We report a cesium sulfonate metal organic framework (Cs3(L)(H2O)3.3, 1, L = 1,3,5-trisulfonato-2,4,6-trihydroxybenzene) with hydrated channels that conduct protons at 1.1 × 10−5 S cm−1 at 50% relative humidity and 70 °C. Water was crystallographically observed in the structure, and the likely proton-transfer pathway was studied. The material was not robust, and appropriate parameters were employed to ensure meaningful data were extracted from the study.

A new Zr(iv)-based metal–organic framework, termed VNU-23 [Zr6O8(H2O)8(H2SNDC)4], where H2SNDC2− = 4,8-disulfonaphthalene-2,6-dicarboxylate, was synthesized. Subsequently, the anchoring strategy was employed to dock histamine into VNU-23 to enhance the proton conductivity at 95 °C and 85% relative humidity.
