Abstract Realizing environmental compatibility and high power conversion efficiency (PCE) are crucial in the research of organic photovoltaics towards practical application. Applying environmentally friendly bio‐materials into modification cathode interlayer (CIL) is a feasible approach to move both targets. In this research, three edible bio‐acids, ursolic acid, citric malic employed modify PDIN CIL solar cells (OSCs) with non‐fullerene acceptors. Among these bio‐acid modifiers, acid shows its excellent performance improving interfacial contact suppressing charge recombination. It helps obtain good facilitates electron extraction. As result, photovoltaic significantly improved. The average PCE increased from 17.58% control devices 18.35% + Ursolic Acid based devices, maximum 18.54%. champion among reported applications bio‐derived materials for CILs. This study demonstrates successful application bio‐acid, which offers an effective green realize highly efficient OSCs. image

Applying solid additive into the active layer has been demonstrated to be one of most efficient approaches in improving photovoltaic performance organic solar cells (OSCs). Through combination 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile and benzodithiophene units, this work presents a novel donor-acceptor type IC-BDTBr. The IC-BDTBr possesses large dipole moment with an intramolecular charge transfer, attributed push-pull effect S…O noncovalently conformational lock. It is able form strong electrostatic interaction materials, which helps tune miscibility. Thus, transport OSCs significantly promoted by incorporation exhibits suitable energy levels optical absorption, enhances photon response devices. As result, adding improves both photocurrent fill factor OSCs. average power conversion efficiency (PCE) increased from 15.70 % PM6:Y6 control device 16.51 (PCEmax = 16.60 %) 2 wt% This research demonstrates feasible design strategy for additive, applying molecular structure moment.

The cathode interlayer (CIL) plays a crucial role in organic solar cells (OSCs), which can establish an Ohmic contact between the active layer and electrode, lower electron extraction barriers, minimize charge carrier recombination. CIL modification is useful strategy for improving performance of OSCs. Herein, inexpensive water–alcohol‐soluble material known as L‐Arginine (L‐Arg) introduced modifier PFN‐Br CIL, leading to successful optimization quality. Following L‐Arg modification, work function lowered facilitated. assists exciton dissociation while suppressing both bimolecular trap‐assisted recombination processes. modified establishes superior with metal electrode due its enhanced hydrophilicity, helps collection. Consequently, average power conversion efficiency increases from 10.54% reference device 11.17% optimally doped device.

Water/alcohol-soluble cathode interlayers are widely utilized in organic electronic devices. However, the mechanism by which acetic acid (AcOH) facilitates solubility of neutral water/alcohol remains unclear. This paper focuses on AcOH-induced dissolution interlayer materials and establishes quantitative relationships for chemical reactions. It was found that AcOH could react acid-base with amino groups PFN or PDIN, resulting formation trace amounts quaternary ammonium salts, ultimately enhance PDIN methanol. Additionally, this study clarifies debate about role devices: is primarily unprotonated water/alcohol-soluble play a critical interfacial modification rather than protonated produced postacid reaction, lays an important theoretical foundation development high-performance materials.
