Synergistic effect of side-chain engineering and terminal-group halogenation on naphthalenediimide-based non-fused ring electron acceptors for efficient organic solar cells Organic solar cells (OSCs) based on non-fused ring electron acceptors (NFREAs) have shown significant potential for practical application owing to their easily tunable chemical structures and short synthesis routes.

Phthalimide-based Unfused-Ring Non-fullerene Acceptors for Constructing Efficient Organic Solar Cells with High Open-Circuit Voltage Unfused-ring non-fullerene acceptors (UF-NFAs) have garnered substantial attention because of their simple chemical structure and easy synthesis, making them promising candidates for advancing the application of organic solar cells (OSCs).

To achieve efficient non-fullerene polymer solar cells (NF-PSCs), it is important to design and synthesize donor materials. To investigate the substituent effects of electron-withdrawing fluorine atoms and different alkyl chains (–C8C12 or –C10C14) on the thiophene ? bridge, four novel conjugated polymers composed of dicyanodistyrylbenzene (DCB)-based and quinoxaline-based units were synthesized and applied in NF-PSCs photovoltaic devices.
