Light-activated tautomeric transition enhanced buried heterointerface for highly efficient and ultraviolet robust perovskite solar cells

Science China Chemistry 2024年

作者： Sheng Jiang Shaobing Xiong Shuaifei Mao Yefan Zhang Dongyang Zhao Xiaomeng You vladimir Gaishun Dmitry Kovalenk Qinye Bao School of Physics and Electronic Science East China Normal University Shanghai Frontiers Science Research Base of Intelligent Optoelectronics and Perception Institute of OptoelectronicsFudan University Institute of Functional Nano & Soft Materials (FUNSOM) Soochow University Shanghai Key Laboratory of Magnetic Resonance East China Normal University Department of Physics and Information Technologies Francisk Skorina Gomel State University Collaborative Innovation Center of Extreme Optics Shanxi University

The buried heterointerface of perovskite solar cells（PSCs） suffers from serious nonradiative recombination and ultraviolet（UV）light stress, relentlessly limiting further increase in their power conversion efficiency and operational stability. Herein, we develop an emerging strategy of incorporating a thin UV-activated tautomeric transition layer onto underlying charge transport layer and then depositing perovskite layer to construct an efficient hole-selective buried heterojunction. It is revealed that the UV-activated tautomeric transition interlayer not only improves upper perovskite crystallinity, diminishes thermionic loss for collecting hole and passivates defect site at such buried contact that significantly promote charge transport and suppress nonradiative recombination, but also effectively protects adjacent perovskite from UV degradation through “UV sunscreen”effect. As a result, we report a remarkably enhanced efficiency of 24.76% compared to 22.02% of the control device. More importantly, the achieved high-efficiency PSC features excellent resistance against UV radiation at 365 nm of 100 and 850 mW cm-2, which are approximately 21 and 184 times of UV flux(4.6 mW cm-2) under AM 1.5G solar illumination. This work provides a promising approach of strengthening buried heterointerface for simultaneous realization of highly efficient and UV robust PSCs.

The materials studied were lateritic soils from Souza-Mbanga-Cameroon, with a view to their better use in road geotechnics. In order to achieve the set objective, the work was carried out in two phases, firstly in the field, to provide a morpho-structural description of the soil profiles, followed by a laboratory phase to analyse the samples collected in the field. The results of the physical characterisation of the soil samples show that, for average values, the water content is 9.87%, the percentage of fines 48%, the plasticity index 21.6%, the liquidity limit 50.91%, and the consistency index 1.97. These soils are classified as silty sands in the LCPC classification and as fine soils in the GTR classification. The average value of the maximum dry density is 1.81 g/cm3 and that of the water content at the modified Proctor optimum is 16.24%. The CBR index is between 1.8% and 17.8%, showing that these soils belong to classes S1, S2, S3, S4 and S5. Souza-Mbanga lateritic soils can be used in their natural state as subgrades.

楔横轧工艺中常见的心部缺陷问题限制了该工艺在航空航天领域的发展。针对此问题，以GH4169合金楔横轧件为实验对象，采用OM、SEM对轧件的微观组织进行表征，并在轧制前预析出不同含量的δ相，探讨δ相含量对心部缺陷形成的影响。同时，借助有限元数值模拟软件对楔横轧过程中轧件的金属流动、应力、应变等演化规律进行分析。结果表明：楔横轧成形过程中预析出的短小片层状δ相会发生球化行为，转变成短棒状和颗粒状δ相。其中，完全球化的δ相对轧件心部缺陷无明显影响，而未完全球化的片层状δ相在楔横轧过程中因为轴向拉应力和周向剪切应力的共同作用易成为心部裂纹源，导致轧件心部出现缺陷。此外，在分析金属流动规律时发现，轧件心部的金属在径向有异常流动的趋势，且存在异常流动临界半径。

In connection with the current prospect of decarbonization of coal energy through the use of small nuclear power plants (SNPPs) at existing TPPs as heat sources for heat supply to municipal heating networks, there is a technological need to improve heat supply schemes to increase their environmental friendliness and efficiency. The paper proves the feasibility of using the heat-feeding mode of ASHPs for urban heat supply by heating the network water with steam taken from the turbine. The ratio of electric and thermal power of a “nuclear” combined heat and power plant is given. The advantage of using a heat pump, which provides twice as much electrical power with the same heat output, is established. Taking into account that heat in these modes is supplied with different potential, the energy efficiency was used to compare these options. To increase the heat supply capacity, a scheme with the use of a high-pressure heater in the backpressure mode and with the heating of network water with hot steam was proposed. Heat supply from ASHPs is efficient and environmentally friendly even in the case of significant remoteness of heat consumers.
