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)...
Abstract Organic solar cell (OSC) development continues to demonstrate impressive device efficiency improvements. However, the materials synthetic simplicity essential industrialization remains seriously lacking attention, imparting inferior performance records in low‐cost devices. Hence, low bandgap and completely non‐fused electron acceptors (CNFEAs) having simple molecular structures are investigated herein. In contrast typically explored fused‐ring with smaller backbone conformational...
Abstract Single‐component organic solar cells based on double cable polymers have achieved remarkable performance, with DCPY2 reaching a high efficiency of over 13%. In this study, is further optimized an 13.85%, maintaining fill factor (FF) without compromising the short circuit current. Despite its intermixed morphology, shows reduced recombination rate compared to their binary counterpart (PBDB‐T:Y‐O6). This slower in attributed wavefunction overlap delocalized charges, by spatially...
Fluorescence imaging in the near-infrared II (NIR-II, 1000-1700 nm) region opens up new avenues for biological systems due to suppressed scattering and low autofluorescence at longer-wavelength photons. Nonetheless, development of organic NIR-II fluorophores is still limited mainly shortage efficient molecular design strategy. Herein, we propose an approach designing Janus by introducing electronic donors with distinct properties into one molecule. As a proof-of-concept, fluorescent dye 2 TT-
Charge management plays a pivotal role in achieving high-performance bulk heterojunction (BHJ) organic solar cells (OSCs). In this study, two efficient polymer donors are designed, P[4,8]BBO and P[2,6]BBO, by regulating the conjugation pathways of benzobisoxazoles (BBO) through 4,8- 2,6-linkages, respectively. Comparing to isomer pathway has been proved enable shallower highest occupied molecular orbital (HOMO) energy level -5.20 eV, significantly enhanced luminescence efficiency, reduced...
Organic photodiodes (OPDs) that utilize wavelength-selective absorbing molecules offer a direct approach to capturing specific wavelengths of light in multispectral sensors/imaging systems without filters. However, they exhibit broad response bandwidths, low external quantum efficiency (EQE), and often require compromises two-component photoactive materials. Herein, the first utility boron-nitrogen (BN) single-component photoabsorbers, leveraging multi-resonance effect are introduced attain...
