| 2 | Inner alkyl chain modulation of small molecular acceptors enables molecular packing optimization and efficient organic solar cells显示文摘With the generation of Y6,organic solar cells have reached remarkable achievement of over 19%efficiency.Alkyl chain is of importance to modulate intermolecular stacking and possibly enhance optoelectronic properties of small molecule acceptors(SMAs).Three alkyl chains of 2-ethylhexyl,2-butylocyl and 3-ethylheptyl were selected to obtain G6-EH,G6-BO and G6-EHep molecules,respectively.Compared to G6-EH and G6-BO,G6-EHep was found inducing unfavourable large domain size.Furthermore,we discover that 2-butyloctyl effectively inhibits monomolecular and bimolecular recombination,improves molecular packing,generates more balanced carrier mobility and enhances exciton dissociation.The SMA with 2-butyloctyl alkyl chains(G6-BO)shows the best electrical and morphological characteristics,achieving a higher power conversion efficiency(PCE)of 17.06%,with an open circuit voltage of 0.912 V,a short-circuit current of 24.22 m A cm-2and a fill factor of 77.25%.Finally,using the ternary strategy by incorporating the G6-BO acceptor into PM6:BTP-e C9,we achieved a higher PCE of18.13%with enhanced electron transport. | Yuntong Guo Zhenyu Chen Jinfeng Ge Jinna Zhang Lin Xie Ruixiang Peng Wei Ma Ziyi Ge | 2023 | Science China Chemistry2023，66，2： | 0 |
| 3 | Robust optimization design on impeller of mixed-flow pump显示文摘To increase the robustness of the optimization solutions of the mixed-flow pump,the impeller was firstly indirectly parameterized based on the 2D blade design theory.Secondly,the robustness of the optimization solution was mathematically defined,and then calculated by Monte Carlo sampling method.Thirdly,the optimization on the mixed-flow pump′s impeller was decomposed into the optimal and robust sub-optimization problems,to maximize the pump head and efficiency and minimize the fluctuation degree of them under varying working conditions at the same time.Fourthly,using response surface model,a surrogate model was established between the optimization objectives and control variables of the shape of the impeller.Finally,based on a multi-objective genetic optimization algorithm,a two-loop iterative optimization process was designed to find the optimal solution with good robustness.Comparing the original and optimized pump,it is found that the internal flow field of the optimized pump has been improved under various operating conditions,the hydraulic performance has been improved consequently,and the range of high efficient zone has also been widened.Besides,with the changing of working conditions,the change trend of the hydraulic performance of the optimized pump becomes gentler,the flow field distribution is more uniform,and the influence degree of the varia-tion of working conditions decreases,and the operating stability of the pump is improved.It is concluded that the robust optimization method proposed in this paper is a reasonable way to optimize the mixed-flow pump,and provides references for optimization problems of other fluid machinery. | ZHAO Binjuan LIAO Wenyan XIE Yuntong HAN Luyao FU Yanxia HUANG Zhongfu | 2021 | 排灌机械工程学报2021，39，7： | 0 |
