摘要： A method for enhancing aggregation state stability of organic semiconductor (OSC) films includes constructing the OSC film; introducing uniform and discontinuous nanoparticles on a surface of the film or an inside of the film. Electrical properties of the OSC film are not influenced by introducing the nanoparticles. Grain boundary, dislocation, stacking fault, and surface of the film are pinned by the nanoparticles, increasing potential barrier of the aggregation state evolution of the film, and thus enhancing the stability of the aggregation state and greatly improving maximum working temperature and storage lifetime of organic field-effect transistors. Under room temperature storage, morphology of the OSC film introduced with the nanoparticles is difficult to change, so that the stability of electrical properties of organic transistor components prepared from the film is ensured in a high-temperature and atmospheric working environment.

摘要： A polymer solar cell including a cathode buffer layer (CBL) is proposed. the CBL may include a reaction product between a conjugate polymer electrolyte and an acid derivative, the conjugate polymer electrolyte is poly [(9,9-bis 3′-(N,N-dimethylamino) propyl)-2,7-fluorene)-alt-2,7-(9,9-dihexylfluorene)] (PFN), and the acid derivative is trifluoroacetic acid (CF3AA), 4-trifluoromethyl benzoic acid (CF3BA), or 4-toluene sulfonic acid (TsOH). The CBL including the conjugate polymer electrolyte (PFN) modified with a specific acid derivative may improve short-circuit current (Jsc) and a filling factor (FF) simultaneously, and thus, significantly improved efficiency is exhibited.

摘要： Provided in the present disclosure is a photoelectric device. For the photoelectric device, a modification layer is added on the surface of a first electrode layer on the side away from a base substrate. The presence of the modification layer can prevent the direct contact of the first electrode layer and other film layers, thereby alleviating the problem of corrosion of indium-containing oxide which constitutes the first electrode layer. Furthermore, an indium-ion trapping group contained in the modification layer can fix indium ions released after the corrosion of the indium-containing oxide to the surface of the first electrode layer, thereby preventing the indium ions from moving to the inner part of the photoelectric device, which can then increase the service life of the photoelectric device.

摘要： Ultra-narrow bandgap Non Fullerene Acceptors (NFAs) comprising an A-D-A′-D-A structure or an A-D-A′-D′-A′-D-A structure were designed, synthesized, and characterized (where A, A′ are organic acceptor moieties and D and D′ are organic donor moieties). Exemplary NFA materials have narrow bandgap (0.86 eV-0.99 eV). Photovoltaic devices and Near Infrared photodetector devices based on these compositions above were synthesized with controlled amounts of solvents and additives. A photodetector having a specific detectivity of 2.41×1012 Jones (D*) at a wavelength of 1040 nm was achieved.
