Abstract The intrinsic electronic properties of donor (D) and acceptor (A) materials in coupling with morphological features dictate the output organic solar cells (OSCs). New physical intimate eutectic mixing are used nonfullerene‐acceptor‐based D–A 1 –A 2 ternary blends to fine‐tune bulk heterojunction thin film morphology as well their properties. With enhanced crystallinity improved carrier transport, a significant J SC amplification is achieved due formation fibrillar lamellae reduced...

The exploration of high-performance and low-cost wide-bandgap polymer donors remains critical to achieve high-efficiency nonfullerene organic solar cells (OSCs) beyond current thresholds. Herein, the 1,2,3-benzothiadiazole (iBT), which is an isomer 2,1,3-benzothiadiazole (BT), used design donor PiBT. PiBT-based reach efficiency 19.0%, one highest efficiencies in binary OSCs. Systemic studies show that isomerization BT iBT can finely regulate polymers' photoelectric properties including i)...

The origin of the relationship between fill factor (FF) and light intensity (I) in organic disordered-semiconductor-based solar cells is studied. An analytical model describing balance transport recombination charge carriers, parameterized with a factor, ${\mathrm{\ensuremath{\Gamma}}}_{m}$, introduced to understand FF-I relation, where higher values ${\mathrm{\ensuremath{\Gamma}}}_{m}$ correlate larger FFs. Comparing effects direct tail-state-mediated on plot, we find that, for low-mobility...
