This review summarizes the recent progress of DPP-based conjugated materials, including small molecules and polymers, for application in non-fullerene organic solar cells.
Abstract An organic–inorganic hybrid electrolyte based on a cyclic Ti‐oxo cluster as the inorganic core and naphthalene‐based organic ammonium bromide salts was developed with easy synthesis low cost. The new exhibits excellent solubility in methanol, aligned work function, good conductivity, amorphous state thin film, enabling its successful application cathode interlayer solar cells high power conversion efficiency of 17.19 %. This demonstrates that electrolytes are kind semiconductor,...
Ternary organic solar cells (T-OSCs) represent an efficient strategy for enhancing the performance of OSCs. Presently, majority high-performance T-OSCs incorporates well-established Y-acceptors or donor polymers as third component. In this study, a novel class conjugated small molecules has been introduced component, demonstrating exceptional photovoltaic in T-OSCs. This innovative molecule comprises ethylenedioxythiophene (EDOT) bridge and 3-ethylrhodanine end group, with EDOT unit...

The electron transport layer (ETL) plays a crucial role in achieving high performance and stability of organic solar cells (OSCs). ETL materials suffering from low conductivity can impede charge collection transport. Hyperbranched polymers display advantages excellent film-forming property facile preparation, which, however, often show conductivity. In this work, we designed two hyperbranched polymers, HPDIN-B01 HPDIN-B02, integrating the PDIN segments using tribromomethylbenzene cores...
To achieve efficient and stable organic solar cells (OSCs), interfacial dipole suitable wettability are prerequisites for interlayer materials, in addition to the aligned energy level high conductivity. However, these have been rarely realized simultaneously electron-transporting layer (ETL) materials date. Herein, an polymer, PPDIN-C6-F, by integrating perylene diimide (PDI) segment fluorinated alkyl spacer (C6F12) was synthesized via a cost-effective quaternization polymerization reaction....
Conjugated polymers consisting of electron-rich and electron-deficient units as alternative structures have played important roles in the field organic solar cells (OSCs). A thieno[3,4-c]pyrrole-4,6-dione (TPD) unit an has been used to construct conjugated for application fullerene non-fullerene based OSCs. TPD-based monomers can be simply prepared TPD-polymers synthesized via environmentally friendly direct (hetero)arylation polymerization, providing a possibility large quantity...
Despite great achievements having been made in lithium-sulfur batteries (LSBs), further improvements regarding rate performance, cycle life, and operating temperature are needed for realistic applications. Herein, we developed a simple electrospun method the preparation of TiO2 coaxial nanofiber (TCNFs)-modified Celgard separators to suppress polysulfide shuttling. LSBs with TCNF/Celgard separator display excellent electrochemical performance. For an areal sulfur loading 2.5 mg cm-2, cells...
Abstract Organic solar cells (OSCs) with the conventional configuration usually use polyethylenedioxythiophene:polystyrene sulfonate (PEDOT:PSS) as hole‐transporting layer (HTL); however, its acidity tends to affect performance and long‐term stability of devices. Therefore, replacing PEDOT:PSS other more stable HTLs is essential for realizing practical applications OSCs. To achieve this goal, a simple low‐cost vanadyl oxalate (VOC 2 O 4 ) identified HTL facilitate high power conversion...

ZnO as an interlayer plays important role in organic solar cells (OSCs). There are two kinds of interlayers, including sol–gel method-obtained interlayers and those obtained using nanocrystals. While require thermal treatment, nanocrystals can generate thin film without extra treatment. However, solution usually unstable due to strong aggregation, limiting their long-term application. In this work, we reported a method stabilize by ligand dimethylglycine. The resulting ZnO–N exhibit high...
