Thermal stability of perovskite materials is an issue impairing the long-term operation of inverted perovskite solar cells(PSCs). Herein, the thermal attenuation mechanism of the MAPb I3films that deposited on two different hole transport layers(HTL), poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS) and poly(3,4-ethylenedioxythiophene)(PEDOT), is comprehensively studied by applying a heat treatment at 85℃. The thermal stress causes the mutual ions migration of I, Pb and Ag through the device, which leads to the thermal decomposition of perovskite to form Pb I2. Interestingly, we find that I ions tend to migrate more towards electron transport layer(ETL) during heating, which is different with the observation of I ions migration towards HTL when bias pressure is applied. Moreover, the use of electrochemical deposited PEDOT as HTL significantly decreases the defect density of MAPb I3films as compared to PEDOT:PSS supported one. The electrochemical deposition PEDOT has good carrier mobility and low acidity, which avoids the drawbacks of aqueous PEDOT:PSS. Accordingly, the inverted PSCs based on PEDOT show superior durability than that with PEDOT:PSS. Our results reveal detailed degradation routes of a new kind of inverted PSCs which can contribute to the understanding of the failure of thermal-aged inverted PSCs.

时间反转镜可在没有任何先验知识的情况下具有自适应匹配声信道的作用。主动式时间反转镜(ATRM)要求阵元收发合置,且信号需两次经过信道,效率低下,而阵处理则进一步增加了系统的复杂性,难以满足水声通信节点追求结构简单、低功耗的要求。为克服上述弊端,提出应用单阵元被动式时间反转镜(PTRM)和虚拟式时间反转镜(VTRM),并对单阵元时间反转镜的聚焦增益进行了讨论。计算机仿真结果表明,单阵元时间反转镜可聚焦多途信号,实时实现自适应信道均衡,从而抑制码间干扰、提高信噪比。
