Abstract Rational regulation of Me‐4PACz/perovskite interface has emerged as a significant challenge in the pursuit highly efficient and stable perovskite solar cells (PSCs). Herein, an organometallic molecule aluminum glycinate (AG) that contained amine (‐NH 2 ) hydroxyl (Al‐OH) groups is developed to tailor buried minimize interface‐driven energy losses. The Al‐OH selectively bonded with unanchored O═P‐OH bare NiO‐OH optimize surface morphology levels, while ‐NH group interacted specifically Pb 2+ retard crystallization, passivate Pb‐related defects, release residual stress. These interactions facilitate carrier extraction reduce losses, thereby realizing balanced charge transport. Consequently, AG‐modified narrow bandgap (1.55 eV) PSC demonstrates efficiency 26.74% (certified 26.21%) fill factor 86.65%; wide (1.785 realizes 20.71% champion excellent repeatability. PSCs maintain 91.37%, 91.92%, 92.00% their initial after aging air atmosphere, nitrogen‐filled atmosphere at 85 °C, continuously tracking maximum power‐point under one‐sun illumination (100 mW cm −2 for 1200 h, respectively.

Ferrocene Interlayer for a Stable and Gap-Free P3HT-Based Perovskite Solar Cell as a Low-Cost Power Source for Indoor IoTs

ACS Photonics, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 15, 2025

Although poly(3-hexylthiophene-2,5-diyl) (P3HT) with its stability-boosting hydrophobic surface is a promising low-cost alternative dopant-free hole transport material for n-i-p perovskite solar cells (PSCs), the P3HT-based PSCs suffer from energy mismatch between hydrophilic and P3HT, which results in interlayer gap, poor electronic contact, charge extraction. In this study, ferrocene (Fc) acts as an at perovskite/P3HT interface, inducing replacement of edge-on stacking alkyl side chains π–π thiophene rings within P3HT structure to mitigate such mismatch. With optimal amount Fc, average PCE 23.6% has been achieved under indoor light 1000 lux comparison 20.6% without Fc. addition, unencapsulated device can retain 80% initial (T80) over 12 months dark 70% RH, longer than T80 8 Finally, Bluetooth sensor module powered by three Fc-passivated connected series demonstrate capacity replacing batteries used Internet Things (IoTs).

Abstract Developing low‐dimensional perovskites to enhance both single‐junction and tandem solar cells is of great interest for improving photovoltaic performance durability. Herein, a novel 1D perovskite based on 1,3‐thiazole‐2‐carboximidamide (TZC) cation introduced, which exhibits robust chemical interactions with PbI 2 3D perovskite, enabling the fabrication high‐quality mixed‐dimensional films identified by HR‐TEM GIWAXS analyses. Benefiting from lower formation energy barrier perovskites, they can preferentially form act as crystal seeds regulate crystallization kinetics optimized morphology improved crystallinity. In addition effectively passivating surface defects suppressing nonradiative recombination, TZC‐enabled exhibit pronounced n‐type doping characteristics, leading an elevated Fermi level (from −4.63 −4.44 eV) facilitating charge carrier extraction transport in p‐i‐n devices. As result, this strategy not only significantly enhances power conversion efficiency (PCE) widely studied 1.55 eV bandgap but also boosts PCE 1.68 1.85 wide‐bandgap devices, achieving outstanding PCEs 22.52% 18.65%, respectively.
