基于共轭聚合物给体(D)/富勒烯受体(A)的聚合物太阳能电池,由于其低成本、柔性等特点,依然是光伏产业的重要方向.目前,其核心问题是光电转换效率仍达不到产业化的要求.多年来,基于激子理论的指导,尽管聚合物太阳能电池的光电转换效率已突破10％,但是,一方面基于该理论指导下的聚合物太阳能电池器件效率的提升已越发困难,另一方面,超快电荷分离现象的发现也对该理论提出了挑战.2012 年,Kaake 等人通
N-type semiconductor indium tin oxide(ITO)nanoparticles are used to effectively suppress the fluorescence blinking of single near-infrared-emitting CdSeTe/ZnS core/shell quantum dots(QDs),where the IT
A small-molecular acceptor,tetraphenylpyrazine-perylenediimide tetramer(TPPz-PDI4),which has a reduced extent of intramolecular twisting compared to two other small-molecular acceptors is designed.Ben
Although bright organic mechanoluminescence(ML)has been observed for a few luminophores with aggregation-induced emission(AIE),a feasible design principle for the AIE-ML compounds has not yet been pre
Recently,by selecting of the high-performance polymer PBDB-T as the electron donor1 and ITIC2 as the small molecule acceptor(SMA),the power conversion efficiencies(PCEs)in non-fullerene polymer solar
Two porphyrin small molecules substituted with either a furan-or a selenophenelinked diketopyrrolopyrrole unit have been designed and synthesized as an electron donor material for bulk heterojunction(
Organic-inorganic lead halide perovskites have attracted much attention because of their unique merits,such as excellent optical absorption,long-balanced carrier diffusion length and low-cost processi
Organic field-effect transistors(OFETs)becomes essential components in future flexible,wearable and portable electronic devices to be applied in such as identification tags,sensors and flat-panel disp
Compared with the development of novel organic dyes,co-sensitization is a much more convenient way to achieve highly efficient dye-sensitized solar cells(DSSCs).1 Here,four dyes(LD01-LD04)were designe
