| 1 | The Main Progress of Perovskite Solar Cells in 2020-2021显示文摘Perovskite solar cells(PSCs)emerging as a promising photovoltaic technology with high efficiency and low manufacturing cost have attracted the attention from all over the world.Both the efficiency and stability of PSCs have increased steadily in recent years,and the research on reducing lead leakage and developing eco-friendly lead-free perovskites pushes forward the commercialization of PSCs step by step.This review summarizes the main progress of PSCs in 2020 and 2021 from the aspects of efficiency,stability,perovskite-based tandem devices,and lead-free PSCs.Moreover,a brief discussion on the development of PSC modules and its challenges toward practical application is provided. | Tianhao Wu Zhenzhen Qin Yanbo Wang Yongzhen Wu Wei Chen Shufang Zhang Molang Cai Songyuan Dai Jing Zhang Jian Liu Zhongmin Zhou Xiao Liu Hiroshi Segawa Hairen Tan Qunwei Tang Junfeng Fang Yaowen Li Liming Ding Zhijun Ning Yabing Qi Yiqiang Zhang Liyuan Han | 2021 | Nano-Micro Letters2021，13，10： | 2 |

| 3 | Tri-functionalized TiOxCl4-2x accessory layer to boost efficiency of hole-free, all-inorganic perovskite solar cells显示文摘Tin dioxide(SnO2) is generally regarded as a promising electron-transporting layer(ETL) for state-of-theart perovskite solar cells(PSCs), however, the ubiquitous oxygen-vacancy-related defects at SnO2 surface and the large energy difference between conduction band of SnO2 and perovskite layer undoubtedly cause severe charge carrier recombination, resulting in sluggish charge extraction efficiency and non-negligible open-circuit voltage(Voc) loss. Herein, a chlorine-containing TiOxCl4-2x accessory layer is fabricated by immersing SnO2 layer into the TiCl4 aqueous solution to passivate the surface oxygen-vacancy-related defects of SnO2 layer and to set an intermediate energy level at ETL/perovskite interface in all-inorganic cesium lead tri-bromine(CsPbBr3) PSCs. Furthermore, the TiOxCl4-2x layer also improves the infiltration of SnO2 layer surface toward perovskite precursor for high-quality perovskite film. Finally, the hole-free, allinorganic CsPbBr3PSC with a structure of FTO/SnO2/TiOxCl4-2x/Cs0.91Rb0.09PbBr3/carbon achieves a champion efficiency of 10.44% with a Vocas high as 1.629 V in comparison to 8.31% for control device. Moreover, the optimized solar cell presents good stability in 80% humidity in air. | Qingwei Zhou Jialong Duan Yudi Wang Xiya Yang Qunwei Tang | 2020 | Journal of Energy Chemistry2020，29，11： | 1 |

| 5 | Reducing defect of inorganic perovskite film by sulphur-containing Lewis base for robust photodetectors显示文摘Sluggish charge transfer in perovskite film induced by inherent defects such as uncoordinated Pb2+undoubtedly hinders the rapid response of self-powered photovoltaic-typed detector.Based on interaction between Lewis acids and bases,herein,we employ thiourea molecule as a multifunctional Lewis base to significantly improve the quality of all-inorganic CsPbIBr2 perovskite film.After careful characterizations,the quality of perovskite film has been well regulated.Arising from the reduced defect and the reinforced the interfacial charge extraction owing to the strong interaction between uncoordinated Pb2+ions and the-C=S groups in thiourea and the formation of hydrogen bond at perovskite/TiO_(2) interface,an enhanced responsivity of 0.335 A W-1 and specific detectivity of 3.92×10^(12) Jones has been achieved for the self-powered,carbon-electrode based photodetector,which is comparable to the state-of-theart device based on CsPbIBr2 film.More importantly,the device free of encapsulation remains 82.8%of initial performance after storage over 56 days in ambient atmosphere,promoting the practical deployment of perovskite products. | Jian Du Jialong Duan Xiya Yang Qingwei Zhou Yanyan Duan Tingting Zhang Qunwei Tang | 2021 | Journal of Energy Chemistry2021，30，10： | 1 |

| 8 | Review on engineering two-dimensional nanomaterials for promoting efficiency and stability of perovskite solar cells显示文摘Perovskite solar cell(PSC) has gradually shown its great superiority in photovoltaic filed to compete commercial solar cells owing to its great advantages, such as high efficiency and low fabrication cost. On the way towards commercialization, great efforts have been achieved by accelerating charge extraction and reducing carrier recombination. Recently, two-dimensional(2 D) layered materials have attracted increasing interests for application in PSCs due to their distinctive chemical and physical properties, such as high carrier mobility and tunable bandgap, which greatly determines the perovskite film growth kinetics, carrier transfer and stability of PSCs. Therefore, with the aim to better understand their recent development and application in PSC, in this review, the emerging 2D materials beyond graphene as charge transport layers, buffer layers and additives in perovskite film for enhancing the efficiency and stability of PSCs are summarized. However, there are still some crucial challenges to be addressed for commercialization. Finally, the challenges and prospects of these 2D nanomaterials for application in PSCs are further proposed for future development. | Qingwei Zhou Jialong Duan Yanyan Duan Qunwei Tang | 2022 | Journal of Energy Chemistry2022，31，5： | 1 |

| 20 | Dissolution Characteristic Study on Dustfall in Citric显示文摘In this paper, the dissolution characteristics of Xining dustfall in citric acid solution was studied to evaluate the physical chemical change in acid conditions. pH along with conductivity was tested with time. FTIR, SEM and ICP analysis were applied to analyze the residuum and filtrate after 2 days’ dissolution experiment. It was shown in the pH/conductivity variation, solution’s pH rise sharply in the front 4 hours, then decrease slowly. After 4 hours, both the pH and conductivity become stable. Based on combined analysis of XRD and FTIR spectrum of dustfall before and after dissolution, that calcite and dolomite in dustfall are dissolved completely in the 0.05M citric acid solution in two days. Besides, amount of metal cations were extracted from the dustfall during the dissolution, including Ca2+,K+,Mg2+,Fe3+,Al3+,Si. In general, after the dissolution of dustall in citric acid, some minerals are dissolved and amount of metal elements are extracted. Carbonate minerals almost dissolved completely, also the structure of silicate minerals changed as the extraction of elements. | TANG Jun DONG Faqin DAI Qunwei DENG Yuequan ZHOU Shiping CHEN Wu | 2013 | 矿物学报2013，33，S1： | 0 |
