Stable and Efficient Semitransparent Organic Photovoltaics Enabled by Cathode Interface Engineering

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

Published: May 19, 2025

Abstract Cathode interface engineering is a critical strategy for enhancing power conversion efficiency and device stability in semitransparent organic photovoltaics (STOPVs). Herein, novel approach of using trithiocyanuric acid trisodium salt (TATS) proposed to strengthen the chemical interactions between cathode interlayer (CIL) ultrathin silver (Ag) electrode. The introduction TATS not only improves conductivity CIL, but also promotes growth Ag electrodes stabilizes morphology films, thus simultaneously improving light utilization (LUE) photostability STOPVs. LUE STOPVs improved from 3.62% 3.98% after modification with TATS, further enhanced 4.30% by 35 nm molybdenum oxide as optical structure. In addition, significantly retention rate initial 53% 85%, 200 h continuous illumination. This study offers new perspective on achieving high‐efficiency through CIL strategy.

Abstract Phenazine‐based small molecular acceptors (SMAs), which benefit from the reduced energy loss ( E ), have emerged as promising candidates for achieving high‐efficiency organic solar cells (OSCs). Nevertheless, potential advancements of phenazine‐based photovoltaic devices are hindered by constrained short‐circuit current J sc ). Though incorporation selenium (Se) atoms has been proven effective in enhancing , it simultaneously introduces disorder stacking and charge recombination. Based on desire to harness full phenazine structure benefits Se substitution, a series Se‐substituted SMAs, namely PzIC‐SSe‐4F PzIC‐SeSe‐4F meticulously synthesized. Due increased photon harvesting capabilities, device using demonstrated significantly 27.73 mA cm −2 . Remarkably, PzIC‐SeSe‐4F‐based displayed an astonishing open circuit voltage V oc ) 0.873 V, representing highest recorded among all reported symmetric Y‐series SMAs‐based devices. Thanks synergistic effect central cores PM6:PzIC‐SeSe‐4F‐based achieves power conversion efficiency (PCE) 17.69%. The findings serve pivotal reference further development
