Phenethylamine（PEA） was successfully introduced into hole-conductor-free, fully printable mesoscopic MAPbI3 perovskite solar cells（MPSCs） with a carbon electrode by mixing phenethylammonium iodide with MAPbI3 perovskite solution. PEA-MAPbI3 films show better pore filling into TiO2 scaffold that forms better contact, and induce longer exciton lifetime and higher quantum efficiency of photoinduced charge separation. As a result, the power conversion efficiency of PEA-MAPbI3 MPSCs is 37% higher than that of MAPbI3 MPSCs. And PEA-MAPbI3 MPSCs show excellent long-term stability that could keep 90% of origin power conversion efficiency for over 80 days in the air.

针对现有电动汽车充电需求分析因假设充电设施充足且用户出行规律不变而导致分析结果准确性不高的问题,提出一种考虑充电设施充裕性的电动私家车用户出行与充电需求时序交互分析方法。首先,结合出行链概念和蒙特卡洛方法建立电动私家车用户的出行需求模型。其次,在用户处于不同出行状态时分别建立基于出行需求的电量消耗模型、基于模糊理论的充电需求产生模型、考虑充电设施充裕性的电量补充模型和考虑用户差异性决策的充电反馈效应模型,其中充电需求产生模型和充电反馈效应模型实现了出行需求与充电需求的交互。进而,以等步长时钟推进方式进行闭环模拟,完成出行与充电需求的时序交互分析。最后,通过算例仿真验证了所提模型和方法的有效性,分析了充电设施充裕性变化时用户充电需求的变化趋势以及出行需求的迟滞和恢复。

Dual-functional NiCo2S4 polyhedral architectures with outstanding electrochemical performance for supercapacitors and lithium-ion batteries(LIBs) have been rationally designed and successfully synthesized by a hydrothermal method. The as-synthesized NiCo2S4 electrode for supercapacitor exhibits an outstanding specific capacitance of 1298 Fg-1 at 1 A g-1 and an excellent rate capability of ~80.4% at20 A g-1. Besides, capacitance retention of 90.44% is realized after 8000 cycles. In addition, the NiCo2S4 as anode in LIBs delivers high initial charge/discharge capacities of 807.6 and 972.8 m Ah g-1 at 0.5 C as well as good rate capability. In view of these points, this work provides a feasible pathway for assembling electrodes and devices with excellent electrochemical properties in the next generation energy storage applications.
