As one of the core parts of two-terminal(2 T) monolithic tandem photovoltaics, the interconnecting layers(ICLs) play a critical role in modulating the carrier transport and recombination between the sub-cells,and thus influencing the tandem device performance. Here, for the first time, the relationship between ICLs architecture and 2 T monolithic perovskite/organic tandem device performance has been studied by investigating the change of ICLs composition layer thickness on the ICLs optical and electrical properties, sub-cells EQE properties, and tandem device J-V properties. It is revealed that the ability of ICLs on modulating the sub-cells carrier balance properties is strongly associated with its composited layers thickness, and the tandem device carrier balance properties can be reflected by the relative EQE intensity between the sub-cells. Finally, with a deep understanding of the mechanisms, rational design of ICLs can be made to benefit the tandem device development. Based on the optimized ICL a high PCE of 20.03% is achieved.

Interface Engineering and Morphology Control for High Performance Perovskite/Organic Hybrid Planar Heterojunction Solar Cells

第三届新型太阳能电池学术研讨会

作者：叶轩立 qifan xue Chen Sun Kai Zhang Fei Huang Yong Cao State Key Laboratory of Luminescent Materials and Devices South China University of Technology

Interface engineering is a critical strategy for improving the performance of both polymer and organometal trihalide perovskite(*** PbI) solar cells.A good interfacial material should fulfill several requirements including 1) good charge selectivity to improve the charge collection efficiency at the corresponding electrodes,2) matched energy levels with the conduction band and valence band of the light harvesting film to maximize the photovoltage of the solar cells,3) high conductivity to minimize the interfacial resistance loss and forming Ohmic contact with the electrodes.1 In the first part of my talk I will discuss several strategies to design new conjugated polymer‐based interfacial materials with desired electrical conductivity,energy levels and processibility to improve the charge collection efficiency of polymer single solar cells.2 The application of these interfacial materials as interconnection layer for highly efficient tandem polymer solar cells will also be discussed.3 In the second part of my talk,I will discuss how we can apply the knowledge we learned from the interface engineering of polymer solar cells to design new class of electron transport layer 4,5 and hole transport layer materials 6,7 to improve the performance of perovskite solar cells.

In this talk I will present two strategies to improve the performance of perovskite/organic planar heterojunction solar cells. First, the growth kinetic of the perovskite films was tuned by introducing chemically-tailored processing additives. Depending on the choice of the additives, the crystallinity and coverage of the perovskite films can either be enhanced or suppressed and we found that the solar cell performance was strongly depending on the morphology of the perovskite films.1,2 Second, novel interfacial materials were introduced to improve the contact between the fullerene electron transport layer and the metal cathode interface, resulted in Ohmic contact with reduced interfacial resistance and a significant improvement on the fill factor. 3 We will also discuss new strategy to design novel electron transporting conjugated polymers as efficient electron selective interlayer and also the design of new hole transporting polymers as efficient hole selective interlayer for fullerene-free hybrid pervoskite solar cells. Combining these two strategies high performance perovskite solar cells with PCE over 17% were achieved.

提出了一种融合预瞄特性的智能电动汽车稳定性前馈+反馈控制方法。建立车辆预瞄模型,通过汽车在环境感知时的前视行为,引入道路曲率作为车辆动力学特性的影响因素。基于在前视信息指导下的车辆位姿变化,根据道路附着能力和车速指数模型描述期望纵向车速,建立轮胎侧偏刚度补偿的稳定性前馈控制方法。同时,采用模型预测控制(MPC)设计稳定性反馈控制律,根据车辆的预瞄信息自适应调整预测模型参数和预测时间,消除前馈控制误差及路面扰动等不确定性因素带来的影响。研究结果表明,本文提出的控制策略下汽车质心侧偏角、横摆角速度和侧向加速度小,且跟踪精度更高。仿真试验中,相比于无控制、MPC反馈控制与前馈+定参数MPC反馈控制,本文提出的控制策略在双移线工况1下质心侧偏角峰值分别减小了41.3%、28.9%和10.0%,横摆角速度峰值分别减小了18.0%、6.7%和2.0%,双移线工况2下质心侧偏角峰值分别减小了27.2%、8.7%和8.0%,横摆角速度峰值分别减小了16.9%、12.9%和8.6%;相比于MPC反馈控制与前馈+定参数MPC反馈控制,在蛇行工况1下,质心侧偏角峰值分别减小了49.8%与34.8%,横摆角速度峰值分别减小了21.8%与12.7%;在蛇行工况2下,质心侧偏角峰值分别减小了36.6%和18.6%,横摆角速度峰值分别减小了17.7%和12.4%。
