摘要
巨分子受体(GMAs)由两个或多个窄带隙小分子受体(SMAs)亚基通过共轭或非共轭连接单元连接而成,它具有 SMAs 的宽吸收、适当的电子能级和固定分子量(具有良好的光伏性能重现性),以及聚合 SMAs(PSMAs)的良好成膜性、高形态稳定性和光稳定性等优点。因此,GMAs 在聚合物太阳能电池(PSCs)中的商业应用前景广阔。因此,最近 GMAs 引起了极大的关注。在本综述中,我们将简要介绍窄带隙 SMA 的发展,尤其是 A-DA'D-A 结构 SMA 和 PSMA。然后,我们将重点介绍 GMAs 的最新研究进展,包括 GMAs 的合成方法以及 SMA 子单元数量对 GMAs 光伏性能的影响。最后,我们将提出自己的观点,并对 GMAs 的进一步发展进行简要展望。
Giant molecule acceptors for high performance polymer solar cells
Giant molecule acceptors (GMAs) are composed of two or more narrow bandgap small molecule acceptors (SMAs) subunits connected by conjugated or non-conjugated linking units, which possesses the advantages of the SMAs with broad absorption, appropriate electronic energy levels and fixed molecular weight (with good photovoltaic performance reproducibility), and the polymerized SMAs (PSMAs) with good film-forming property and high morphology stability and photo-stability. So that the GMAs are promising for future commercial application in polymer solar cells (PSCs). Therefore, the GMAs have attracted great attention recently. In this review, we will briefly introduce the development of the narrow bandgap SMAs, especially the A-DA’D-A structured SMAs, and the PSMAs. Then we will focus on the recent research progress of the GMAs, including the synthetic method of GMAs and the effect of number of the SMA subunits on the photovoltaic performance of the GMAs. Finally, we present our perspectives and offer a concise outlook on the further advancement of the GMAs.
期刊介绍:
Giant is an interdisciplinary title focusing on fundamental and applied macromolecular science spanning all chemistry, physics, biology, and materials aspects of the field in the broadest sense. Key areas covered include macromolecular chemistry, supramolecular assembly, multiscale and multifunctional materials, organic-inorganic hybrid materials, biophysics, biomimetics and surface science. Core topics range from developments in synthesis, characterisation and assembly towards creating uniformly sized precision macromolecules with tailored properties, to the design and assembly of nanostructured materials in multiple dimensions, and further to the study of smart or living designer materials with tuneable multiscale properties.
