Fabrication of Bifacial-Modified Perovskites for Efficient Semitransparent Solar Cells with High Average Visible Transmittance

Molecules, Journal Year: 2025, Volume and Issue: 30(6), P. 1237 - 1237

Published: March 10, 2025

Semitransparent perovskite solar cells (PSCs) that possess a high-power conversion efficiency (PCE) and high average visible light transmittance (AVT) can be employed in applications such as photovoltaic windows. In this study, bifacial modification comprising buried layer of [4-(3,6-Dimethyl-9H-carbazol-9-yl) butyl] phosphonic acid (Me-4PACz) surface passivator 2-(2-Thienyl) ethylamine hydroiodide (2-TEAI) was proposed to enhance device performance. When the concentrations Me-4PACz 2-TEAI were 0.3 mg/mL 3 mg/mL, opaque PSCs with 1.57 eV absorber achieved PCE 22.62% (with VOC 1.18 V) retained 88% their original value after being stored air for 1000 h. By substituting metal electrode an indium zinc oxide electrode, resulting semitransparent showed over 20% AVT 9.45%. It was, therefore, suggested synergistic effect improved crystal quality perovskites carrier transport devices. employing wider bandgap (1.67 eV), corresponding PSC obtained higher 20.71% maintained 18.73%; these values show superior overall performance is observed compared similar studies. This work conductive future application PSCs.

Crosslinked Conjugated Interlayer Network for Efficient and Stable Wide‐Bandgap Perovskite and All‐Perovskite Tandem Solar Cells

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 19, 2025

Abstract Compared to single‐junction perovskite solar cells (PSCs), all‐perovskite tandem (PTSCs) offer higher power conversion efficiencies (PCEs). However, the substantial open‐circuit voltage ( V OC ) loss of wide‐bandgap (WBG) sub‐cells limits efficiency due interface defect and halide segregation. In this study, 6‐hydroxy‐2‐naphthalenecarboxylic acid (HNA) is employed construct cross‐linked network by H‐bond conjugated interaction engineer suppress Enhanced Photoluminescence (PL) intensity reduced quai‐Fermi level splitting (QFLS) indicate that unique molecular conformation HNA facilitates process dense crosslinked film, which greatly enhances passivation effect. Meanwhile, strong π‐π interactions accelerate charge transport at WBG perovskite/C 60 interface, effectively suppressing non‐radiative recombination. The 1.78 eV PSCs achieve a 1.35 PCE 19.92% deliver T 80 = 1100 h maximum point track (MPPT). combination with narrow‐bandgap (NBG) sub‐cells, PTSCs exhibit 2.13 V, 28.25%, 500 h. This work provides self‐assembled interlayer strategy develop highly efficient stable for PTSCs.
