Опубликована: Март 16, 2025

Abstract Boosting power conversion efficiency (PCE) of organic solar cells (OSCs) has been restricted by its undesirably high energy loss, especially for those nonhalogenated solvent‐processed ones. Here,a dichloro‐methoxylated terminal group in an asymmetric small molecular acceptor design, which realizes a significantly reduced non‐radiative loss (0.179 eV) compared to symmetric counterpart (0.202 eV), is reported. Consequently, the device improved up 20% PM6:BTP‐eC9‐4ClO, without sacrificing photon harvest or charge transport ability control system PM6:BTP‐eC9. Further characterizations reveal BTP‐eC9‐4ClO's blend film demonstrates suppressed triplet state formation, enabled enhanced electron delocalization. In addition, BTP‐eC9‐4ClO found be thermally stabler than BTP‐eC9, and thus providing stability, whose T80 value reaches > 7800 h under 80 °C anneal N 2 via linear extrapolation. This work represents state‐of‐the‐art performance binary OSCs with certified results (19.45%).

Nanomanufacturing, Год журнала: 2024, Номер 4(2), С. 81 - 98

Опубликована: Апрель 1, 2024

Organic solar cells (OSCs) are becoming increasingly popular in the scientific community because of their many desirable properties. These features include solution processability, low weight, cost, and ability to process on a wide scale using roll-to-roll technology. Enhancing efficiency photovoltaic systems, particularly high-performance OSCs, requires study into not only material design but also interface engineering. This demonstrated that two different types OSCs based PTB7-Th:IEICO-4F PM6:Y6 active layers use ZnO bilayer electron transport layer (ETL). The ETL comprises nanoparticle (ZnO NP) created from sol-gel. effect incorporating NPs (ETL) was studied; particular, effects electrical, optical, morphological properties initial were analyzed. films carry charges is improved by addition nanoparticles (NPs), which increase conductivity. structure had better crystallinity smoother film surface than single-layer sol-gel ETL. led consistent strong interfacial connection between photoactive Therefore, inverted organic with as exhibit power conversion other when technique.

In this study, seven new molecules (OA1–OA7) were introduced with the goal of enhancing photovoltaic efficiency solar cells. All these evaluated by using density functional theory (DFT). designed have shorter band gap and higher values [Formula: see text] than reference. For confirming charge mobility, optoelectronic characterization has been carried out densities states (DOS), transition matrix (TDM), molecular electrostatic potential (MEP) reorganization energy. The in also improved. stability was confirmed analysis non-covalent interactions (NCIs). These results elaborate on superiority novel-designed over pre-existing (R) molecule as blocks for better organic cell applications.
