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.

A new Cu(Ⅰ) coordination polymer(CP) formulated as [Cu2(L)(CN)2]n(1, L =1,1′-bis(5,6-dimethylbenzimidazole)methane) was synthesized, in which the cyanide anions were generated in situ by the cleavage of C–C bond of acetonitrile under hydrothermal conditions. CP 1 was characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. It crystallizes in the orthorhombic system, Pccn space group, with a = 10.314(3), b = 20.966(7), c =9.432(3)?, V = 2039.5(11)?3, Z = 4, C21 H20 Cu2 N6, Mr = 483.51, Dc = 1.575 g×cm^-3,μ= 2.105 mm-1 and F(000)= 984, the final R = 0.0608 and wR = 0.1942 for 1226 observed reflections with Ⅰ> 2s(Ⅰ)for the CP 1. The CP 1 possesses a 2D {63} layer structure which is composed of Cu(Ⅰ) centers bridged by L and CN– ligands. The thermal stability and luminescence properties of CP 1 are discussed in detail. The complex also displays a remarkable activity for the degradation of methyl orange by hydrogen peroxide in a Fenton-like process.

Modified CNS-Ⅱ F/M steel was designed for in-core components of supercritical water cooled reactor. Study on the hot deformation behavior of modified CNS- Ⅱ F/M steel is of great importance for processing parameter planning and microstructure controlling during hot deformation. The hot deformation behavior of modified CNS-Ⅱ F/M steel was investigated through isothermal hot compression test at temperature ranging from 1 223 to 1 373 K and strain rate 0.01 to 10 s^-1. The true stress true strain data gained from compression tests were used to built constitu- tive equation of modified CNS-Ⅱ F/M steel. The influence of strain on the accuracy of constitutive analysis was in corporated, assuming strain has a influence on material constants. A 5th order polynominal equation with very good accuracy was used to represent the influence of strain on material constant. The flow stresses calculated from the constitutive equation were compared with test values in the whole experiment range and the absolute average error for the constitutive equation in predicting *** stress is 4. 728 %. At last, the recrystallization behavior of modified CNS-Ⅱ F/M steel was investigated. The relationship of critical strain and peak strain with Zener-Hollomon parameter were given by an experimental equation.
