Perovskite photovoltaic cells are considered as the most promising third generation photovoltaic products due to their high photoelectric conversion efficiency and flexible processing while the high temperature encapsulation process of traditional encapsulation materials can hardly meet the demand of high performance of perovskite photovoltaic modules.In this paper, an adhesive film material by free radical co?polymerization process was successfully synthesized.Light transmission and bonding are characterized by infrared spectroscopy and tensile testing machine,confirming that the polymer is very suitable for chalcogenide photovoltaic cell encapsulation,and that the polymer can be effectively adhered to the chalcogenide solar cell and the outer layer of the glass at 80 ℃.The polymer is suitable for the encapsulation of chalcogenide photovoltaic cells.The photoelectric conversion efficiency of the encapsulated PSCs can reach 20.59%,and the encapsulated PSCs devices show good impact resistance.

In recent years, the global market demand for pressure?sensitive adhesives has shown a steady growth trend. The market demand has reached about 3.5 million tons in 2021, and the estimated size of the global pressure?sensitive adhesive market in 2025 is ＄10 billion. Amid the development of pressure?sensitive adhesive technology and the increase in the application demand for pressure?sensitive adhesives, functionally modified pressure?sensitive adhesives have become a major trend in this field. Acrylate?based pressure?sensitive adhesive is the most widely used pressure?sensitive adhesive at present. Its performance has been improved after modification. Nevertheless, the modification process has some disadvantages, such as environmental pollution and low resource utilization. Since rubber has the advantages of low cost, superb mechanical properties, high and low temperature resistance, and environmental friendliness,and so on.Rubber?modified acrylate?based pressure?sensitive adhesives have become a development trend in this field. This paper summarized the development process of rubber?modified acrylate?based pressure?sensitive adhesives and outlined and compared the types of rubber and the advantages and disadvantages of modified products.

Efficient storage and transportation of hydrogen are the bottlenecks limiting the development of hydrogen economy. One effective way to solve this problem is to store hydrogen in liquid organic hydrogen carriers, such as methanol, which can be released from the organic hydrogen carriers as H2 gas after catalyzed reforming process. The main challenge during this procedure is the development of catalysts capable of executing such a decomposition process. In this work, a novel organometallic compound RuHI(CO)(i⁃Pr⁃Imidazole)(PPh3)2 was synthesized and explored its catalytic applications for hydrogen production during aqueous methanol reforming. The compound was characterized by elemental analysis, infrared spectroscopy, and single⁃crystal X⁃ray diffraction for determining its cystalline structure. The results indicate that the organometallic compound, shows mononuclear structure with six⁃coordinated ruthenium ion in its network, forming the twisted octahedral configuration in the compound. It has been found that reaction conditions such as temperature, the type of alkali, the volume ratio of MeOH and H2O, have profound effects on the reaction efficiencies. Under optimized conditions (110 ℃, 8 mol/L KOH, V(MeOH)/V(H2O)=9∶1),4 μmol the catalyst produces a accumulated TON of 7 9:1 after a 14-day reaction.
