We report all-polymer solar cells(All-PSCs) with record-high power conversion efficiency(PCE) through tuning the molecular weights of the polymer donor(PBDB-T) to form optimal active layer morphology. By combining the polymer donors with a newly reported polymer acceptor(PJ1), an unprecedented high PCE of 15.4% and fill factor over 75% were achieved for the AllPSCs with the medium molecular weight polymer donor(PBDB-TMW), which is the highest value for All-PSCs reported so *** morphology investigation revealed that the proper phase separation in the PBDB-TMW:PJ1 blend should account for the superior device performance as PBDB-TMW exhibits appropriate miscibility with the polymer acceptor PJ1. These results demonstrated that the device performance of All-PSCs could be fully comparable to that of small molecular acceptor-based PSCs. The formation of optimized morphology via precise control of molecular weights of polymer donors and acceptors is crucial to achieve this goal.

Organic and inorganic clusteroluminescence have attracted great attention while the underlying mechanisms is still not well ***,we employed a series of ancient inorganic complexes platinocyanides with aggregation-induced emission property to elucidate the mechanism of clusteroluminescence including how does the chromophore form and how does the solid structures influence the luminescence *** results indicate that the isolated platinocyanide cannot work as a chromophore to emit visible light,while their clusterization at aggregate state can trigger the d-orbitals coupling of the platinum atoms to facilitate the electron exchange and delocalization to form a new chromophore to emit visible ***,the counter ions and H2O ligands help to rigidify the three-dimensional network structure of the platinocyanides to suppress the excited state nonradiative decay,resulting in the high quantum yield of up to 96%.This work fundamentally helps understanding both the organic and inorganic clusteroluminescence phenomenon.

本体异质结有机太阳能电池的活性层形貌对器件性能有着直接的影响。目前广泛应用的形貌表征手段如透射电子显微镜、原子力显微镜等在有机薄膜材料的形貌表征中都存在一定的局限性。共振软X射线散射克服了常用表征手段在有机薄膜表征中对比度低、三维信息缺失等缺点,利用软X射线照射下材料折射率的巨大不同获得更高的对比度,对表征有机太阳能电池活性层的相分离情况、理解微观结构、建立光电转化过程和形貌之间的关系有着重要意义。本文概述了活性层形貌对本体异质结有机太阳能电池性能的影响,介绍了共振软X射线散射的发展历程、基本原理及分析方法。在此基础上,综述了共振软X射线散射在有机太阳能电池形貌问题中应用,并对其应用前景作了展望。
