Abstract Interface engineering is one feasible and effective approach to minimize the interfacial nonradiative recombination stemming from defects, residual stress, energy level mismatch. Herein, a novel steric‐hindrance‐dependent buried interface defect passivation stress release strategy reported, which implemented by adopting series of adamantane derivative molecules functionalized with CO (i.e., 2‐adamantanone (AD), 1‐adamantane carboxylic acid (ADCA), 1‐adamantaneacetic (ADAA)) modify...

Perovskite solar cells suffer from poor reproducibility due to the degradation of perovskite precursor solution. Herein, we report an effective stabilization strategy via incorporating 3-hydrazinobenzoic acid (3-HBA) containing carboxyl (-COOH) and hydrazine (-NHNH2 ) functional groups as stabilizer. The oxidation I- , deprotonation organic cations amine-cation reaction are main causes mixed cation -NHNH2 can reduce I2 defects back thus suppress while H+ generated by -COOH inhibit subsequent...

Perovskite solar cells (PSCs) are now one of the most promising due to advantages such as high‐power conversion efficiency (PCE), low cost, and ease fabrication. Among PSCs, flexible perovskite (FPSCs) lightweight bendable, making them easier transport install than rigid hence can be used in wearable portable electronics, space energy systems, multifunctional integrated buildings, unmanned other applications. Compared with regular n–i–p FPSCs, inverted p–i–n FPSCs possess reliable...

Polyimide (PI) and its derivative polyetherimide (PEI) have been widely investigated as promising candidates for dielectric energy storage due to their excellent intrinsic features. However, most of the current research PI- or PEI-based nanocomposites only focuses on a certain polar group contained in dianhydride monomer, while there are very few studies exploring effect series groups derived from various monomers properties nanocomposites. To fill this gap, we herein fabricated novel...
