The interfacial molecular dipole enhances the photovoltaic performance of perovskite solar cells (PSCs) by facilitating improved charge extraction. However, conventional self-assembled monolayers (SAMs) face challenges like inadequate interface coverage and weak interactions. Herein, we develop a strategy using ferroelectric layer to modify properties PSCs. Specifically, employ 1-adamantanamine hydroiodide (ADAI) establish robust chemical interactions create over perovskite. oriented packing spontaneous polarity ADAI generate substantial dipole, adjusting band bending at anode, reducing misalignment, suppressing recombination. Consequently, our formamidinium lead iodide-based PSC achieves efficiencies 25.13% (0.06 cm2) 23.5% (1.00 while exhibiting enhanced stability. Notably, demonstrate an impressive efficiency 25.59% (certified 25.36%) in 0.06 cm2 area for inverted champion device, showcasing promise SAMs PSCs enhancement. approach with applying monolayer suffers from limited weaker Here, authors molecule construct layer, achieving certified 25.36% cells.

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 21, 2025

2D perovskite materials are ideal candidates for indoor photovoltaic (IPV) applications due to their tunable bandgap, high absorption coefficients, and enhanced stability. However, attaining uniform crystallization overcoming low carrier mobility remain key challenges perovskites, limiting overall performance. In this study, a light-absorbing layer is constructed using Dion-Jacobson (DJ)-phase EDA(FA)4Pb5I16 (n = 5) introduced butylammonium iodide (BAI) interface modification, thereby creating novel DJ/Ruddlesden-Popper (RP) dual heterostructure. By adjusting the thickness of BAI-based layer, relationship between interfacial defect states investigated under varying light intensities. The results indicate that, by achieving balance passivation transport, optimized device reaches power conversion efficiency (PCE) 30.30% an open-circuit voltage (VOC) 936 mV 1000 lux (3000 K LED). 2D-DJ/RP IPV exhibits twentyfold increase in T90 lifetime compared 3D devices. It first time systematically study perovskites applications, demonstrating that rationally designed hold significant potential fabricating high-performance PSCs.

Customized Multifunctional Additive Regulates 1.67 eV‐Wide‐Bandgap Perovskite Crystallization for Four‐Terminal Perovskite/Silicon Tandem Solar Cells

Advanced Materials, Год журнала: 2025, Номер unknown

Abstract Wide‐bandgap (WBG) perovskite solar cells (PSCs, E g > 1.6 eV), serving as the top cell in perovskite/silicon tandem (PSTSCs), play an indispensable role absorbing high energy photons and increasing overall efficiency. However, WBG PSCs often suffer from severe light‐induced phase segregation significant non‐radiative recombination losses due to uncontrolled rapid crystallization. Here, polyfluoride molecular additives are designed incorporated via (diacetoxyiodo)benzene into perovskite, regulate crystallization process of films thereby reduce defects. (Bis(trifluoroacetoxy)iodo)benzene (BTFIB) can passivate uncoordinated lead ions iodide vacancies, inhibiting separation caused by migration reducing loss during charge transport. Moreover, introduction BTFIB effectively moderate film formation confer excellent hydrophobic properties films. Consequently, BTFIB‐based 1.67 eV‐WBG devices yield a champion efficiency 23.05% (certified 22.21%), enabling 31.20% four‐terminal PSTSCs, along with open‐circuit voltage 1.246 V fill factor 85.34%. After 2500 h aging glovebox, device retained 80% its initial

Abstract Organic–inorganic halide perovskite solar cells (PSCs) have demonstrated a promising advancement in flexible and lightweight photovoltaics. Nevertheless, achieving their large‐area printed fabrication remains challenging, especially the issue of defect enrichment at buried interfaces, which is crucial for efficient carrier transport. Herein, an interfacial fastening strategy designed to enhance performance stability PSCs, involving introduction hexamethylene diisocyanate (HDI) into precursor ethylene glycol (EG) on electron transport layers. The situ reaction between HDI EG during film formation can inhibit complex intermediate phases deposition, thus uniform colloidal distribution, mitigating gradient residual stress mismatch films, enhancing contact. resulting rigid, PSCs modules (25 cm 2 ) achieve PCEs 26.04%, 24.16%, 20.40%, respectively, encapsulated devices retain over 80% efficiencies after storage 6380 h. This work provides potential simultaneously optimize contact quality interface crystallization perovskites, aligns with requirements large‐area, high‐quality, homogeneous deposition photovoltaics facilitates printing manufacturing commercialization transition.
