Abstract ：
Perovskite solar cells have gradually become the most attractive alternative for next-generation photovoltaic devices due to their excellent photovoltaic conversion efficiencies and low manufacturing costs. Defect engineering is an essential topic for improving the performance of perovskite devices. In this study, we utilize a bifunctional alkylamine sulfonate to modify the perovskite interfaces. The TsO- of sulfonates coordinates with Pb2+, while -NH2 of alkylamine forms hydrogen bonds with iodine, which reduces charge recombination and improves energy level arrangement. The molecular size and the alkylamine's dielectric constant significantly influence the interface modification performance. For the champion device with BATsO treatment, there is an enhancement in both the fill factor and the open-circuit voltage, resulting in a power conversion efficiency (PCE) of 23.53%. After 400 h of working condition, the device maintains roughly 90.40% of its initial efficiency. Therefore, this study postulates that modifying bifunctional alkylamine sulfonates could effectively enhance the PSC's performance.

Abstract ：
针对目前大部分光伏功率预测模型采用批量离线训练方式，且新建光伏电站训练数据较少的问题，本文提出一种基于增量学习的卷积神经网络（CNN）和长短期记忆（LSTM）网络结合的光伏功率预测模型。首先，采用CNN对气象数据进行特征提取，并通过LSTM网络进行功率预测，以此CNN-LSTM混合模型进行背景学习，训练出可用于增量学习的基准模型。其次，根据不同的时间跨度进行增量学习训练，实现模型的在线更新。针对增量学习中的灾难性遗忘问题，采用弹性权重整合（EWC）算法和在线弹性整合（Online＿EWC）算法进行缓解。实验结果表明，相较于无约束的增量学习，采用EWC和Online＿EWC方法的增量学习可以明显缓解灾难性遗忘问题，降低预测平均绝对误差（MAE）和均方根误差（RMSE）；同时，在保证预测精度的前提下，增量学习的耗时大幅低于传统的批量学习。

Abstract ：
Helicity-dependent photocurrent (HDPC) of the topological surface states (TSSs) in the intrinsic magnetic topological insulator MnBi2Te4 is investigated. It is revealed that the HDPC is mainly contributed by the circular photogalvanic effect (CPGE) current when the incident plane is perpendicular to the connection of the two electrodes, while the circular photon drag effect plays the dominant role when the incident plane is parallel to the connection of the two electrodes. The CPGE current shows an odd function dependence on incident angles, which is consistent with the C 3 v symmetry group of the TSSs in MnBi2Te4. The amplitude of the CPGE current increases with the decrease in temperature, which can be attributed to the increase in mobility at low temperatures, confirmed by the transport measurements. Furthermore, we modulate the CPGE of MnBi2Te4 by applying top gate and source-drain voltages. Compared to Bi2Te3 of the same thickness, the CPGE current of MnBi2Te4 can be more effectively tuned by the top gate because the Fermi level of MnBi2Te4 can be effectively regulated by the top gate, and it is tuned across the Dirac point. This work suggests that the intrinsic magnetic topological insulator MnBi2Te4 is a good candidate for designing opto-spintronics devices.

Abstract ：
The high photovoltaic conversion efficiency (PCE) of ternary organic solar cells (OSCs) based on PTB7-Th, PC71BM and IEICO-4F material is obtained, the short-circuit current density (J SC), fill factor (FF), and open-circuit voltage is 25.90 mA cm-2, 73.20% and 0.71 V, respectively. PCE is as high as 13.53%. It is the highest PCE of ternary OSCs based on PTB7-Th, PC71BM and IEICO-4F materials for all we know. The narrow bandgap material of IEICO-4F is deposited on PTB7-Th:PC71BM bulk heterojunction (BHJ) by layer-by-layer process. We constructed the dual bandgap active layer both BHJ and pseudo-planar heterojunction (P-PHJ), it could be defined as ternary BHJ/P-PHJ of OSCs. This type of OSCs is not only the complementary bandgap material of the active layer, but also increasing the donor/acceptor (D/A) interface. The excitons generation and collection of the device are increased leading a higher J SC and FF. The semitransparent OSCs (ST-OSCs) is prepared by varying the thickness of Ag electrode and PCE can reach 9.70%, and the average visible light transmittance and light use efficiency of ST-OSCs are improved effectively.

Abstract ：
Efficient ternary organic solar cells were achieved by utilizing an ultra-narrow bandgap material, IEICO-4 F, mixed with the fullerene material PC71BM as the acceptor and PTB7-Th polymer as the donor. The different weights of IEICO-4 F were dropped into the active layer to adjust the ratio of acceptor and donor, optimizing the performance of the cells. The results showed the ternary organic solar cells with 10wt% IEICO-4 F could obtain a higher short-circuit current density resulting in the power conversion efficiency (PCE) up to 9.56%. MoO3/Ag/MoO3 as the transparent electrodes of the semitransparent organic solar cell (ST-OSCs) were prepared. The different thicknesses of Ag impacts on the performance of the ST-OSCs were investigated. The PCE of the ternary ST-OSCs was increased to 7.34% and the average visible light transmittance (AVT) was increased to 28.74% when Ag was 10 nm thickness. The ternary ST-OSCs presented both a good light transmittance and a high PCE. In addition, the light utilization efficiency of the ST-OSCs was increased to 2.1%, and the color reproduction index was improved too. The PCE and AVT of the ST-OSCs could improve simultaneously due to the appropriate ratio of the acceptor and donor as well as the optimized transparent electrodes.

Abstract ：
Constructing 2D/3D perovskite heterostructures with organic molecules is key to improving the power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs). However, a comprehensive understanding of the inhibitory relationship between the 2D perovskite layer and ion migration at the interface is still lacking. In this study, we use different alkyl ammonium iodides to build 2D/3D perovskite heterostructures. The research results show that both the chain length of alkyl and amino group count in alkyl ammonium iodide can significantly affect the crystal structure orientation of the 2D perovskite layer. A Dion-Jacobson (DJ) 2D/3D structure treated with ODADI shows superior defect passivation and carrier extraction, leading to PSCs with a 24.51 % PCE. Furthermore, the perovskite based on ODA cations eliminates the influence of Van der Waals interaction in perovskite based on BA or OA cations, which improves the stability of the lattice structure, and significantly inhibits ion migration. Therefore, after a maximum power point stability test of 1500 h, devices retain approximately 88 % of their initial PCE. This work offers fresh insights into optimizing interfaces in 2D/3D PSCs by selecting suitable organic molecules. © 2024
