Flexible perovskite solar cells (f-PSCs) have emerged as potential candidates for specific mechanical applications owing to their high foldability, efficiency, and portability. However, the power conversion efficiency (PCE) of f-PSC remains limited by inferior contact between flexible buried substrate. Here, an asymmetric π-extended self-assembled monolayer (SAM) (4-(9H-dibenzo[a,c]carbazol-9-yl)butyl)phosphonic acid (A-4PADCB) is reported a substrate efficient inverted f-PSCs. Employing this design strategy, A-4PADCB exhibits significant orientation angle away from surface normal, homogenizing distribution potentials. This enhancement improves SAM/perovskite interface quality, controlling growth favorable films with low defect density slight tensile stress.

Flexible perovskite solar cells (pero-SCs) have the potential to overturn application scenario of silicon photovoltaic technology. However, their mechanical instability severely impedes practical applicability, and corresponding intrinsic degradation mechanism remains unclear. In this study, behavior flexible pero-SCs is systematically analyzed under stress it observed that structural failure first occurs in polycrystal film, then extend interfaces. To suppress failure, pentaerythritol triacrylate, a crosslinked molecule with three stereoscopic crosslink sites, employed establish 3D polymer network both interface bulk perovskite. This reduced Young's modulus simultaneously enhanced interfacial toughness. As result, formation cracks delamination, which occur high stress, significantly suppressed pero-SC, consequently retained 92% its initial power conversion efficiency (PCE) after 20 000 bending cycles. Notably, device also shows record PCE 24.9% (certified 24.48%).

Flexible perovskite solar cells (F-PSCs) are appealing for their flexibility and high power-to-weight ratios. However, the fragile grain boundaries (GBs) in films can lead to stress strain cracks under bending conditions, limiting performance stability of F-PSCs. Herein, we show that film facilely achieve situ bifacial capping via introducing 4-(methoxy)benzylamine hydrobromide (MeOBABr) as precursor additive.
