Abstract Inverted perovskite solar cells (PSCs) require efficient, aggregation-resistant hole-transporting self-assembled monolayers (SAMs) at the buried interface. Conventional carbazole-based SAMs, such as 4PACz, suffer from excessive π–π stacking-driven aggregation, leading to inhomogeneous films, elevated trap-state densities, and accelerated device degradation. Here, we report a machine-learn…

ABSTRACT FAPbI 3 perovskite solar cells (PSCs) fabricated via sequential deposition hold great promise for high photovoltaic performance. However, two bottlenecks remain persistent: transport‐limited conversion that leaves residual PbI 2 and the high thermal prerequisite to drive the δ‐to‐α phase transition, both of which deteriorate optoelectronic properties and accelerate degradation under illum…

Abstract Perovskite solar cells (PSCs) have recently gained attention due to their high -power conversion efficiency, low fabrication cost and the increasing global demand for sustainable energy sources. However, the long-term stability of PSCs remains a major challenge. In this context, two-dimensional(2D) perovskites can be seen as a viable solution due to their high stability. This work focuses…

ABSTRACT Scalable fabrication of tin‐based perovskite solar cells (TPSCs) remains challenging due to rapid crystallization, poor film uniformity, and instability of Sn 2+ . Herein, we report a spin‐coating‐free approach, combining blade coating, vacuum‐drying, and controlled dipping methods, to achieve highly crystalline and uniform tin perovskite films. Through systematic studies, we reveal the u…

Abstract To address the environmental concerns and stability limitations associated with conventional lead-based perovskite photovoltaics, this study proposes a lead-free double perovskite solar cell based on an optimized $$\hbox {ITO}$$ / $$\hbox {C}_{60}$$ / $$\hbox {Rb}_{2} \hbox {AgInBr}_{6}$$ / $$\hbox {Cu}_{2}\hbox {NiSnS}_{4}$$ / $$\hbox {Pt}$$ heterostructure. A hybrid computational framew…

Laser processing, as a non-contact, precise, and scalable technique, is playing an increasingly key role in advancing the fabrication of perovskite solar cells (PSCs). This review provides a critical, systematic overview of emerging laser technologies for PSCs, moving beyond simple cataloging of advances. This review covers laser-induced crystallization and defect passivation of the perovskite lay…

Abstract Interfacial instability is a critical constraint for the practical deployment of perovskite solar cells (PSCs), which commonly arises from the metastable residual PbI 2 and deep-level defects like under-coordinated Pb 2+ . Herein, a benzeneseleninic acid (PSA)-enabled interfacial chemical reconstruction strategy, that simultaneously converts residual PbI 2 , mitigates interfacial defects,…

ABSTRACT Perovskite solar cells have achieved remarkable progress as the third‐generation photovoltaics (PVs), owing to their low manufacturing cost and high‐power conversion efficiency, and are now advancing toward industrialization. However, poor long‐term operational stability remains a key obstacle to their industrial commercialization. In particular, when scaling from millimeter‐scale devices…

Purpose This study aims to develop bio-based interfacial materials for organic photovoltaic applications by engineering carotenoid-derived molecular frameworks with favorable energy level alignment and enhanced light-harvesting capability. Design/methodology/approach Three diphenylamine (DPA)-functionalized diquinoxalinocarotene end-group isomers (DQC-DPA1, DQC-DPA2 and DQC-DPA3) were synthesized …
