| 1 | High-performance large-area perovskite photovoltaic modules显示文摘Perovskite solar cells(Pero-SCs)exhibited a bright future for the next generation of photovoltaic technology because of their high power conversion efficiency(PCE),low cost,and simple solution process.The certified laboratory-scale PCE has reached 25.7%referred to small scale(<0.1 cm^(2))of Pero-SCs.However,with the increase of the area to module scale,the PCE drops dramatically mainly due to the inadequate regulation of growing large-area perovskite films.Therefore,there is a dire need to produce high-quality perovskite films for large-area photovoltaic modules.Herein,we summarize the recent advances in perovskite photovoltaic modules(PPMs)with particular attention paid to the coating methods,as well as the growth regulation of the high-quality and large-area perovskite films.Furthermore,this study encompasses future development directions and prospects for PPMs. | Liang Chu Shuaibo Zhai Waqar Ahmad Jing Zhang Yue Zang Wensheng Yan Yongfang Li | 2022 | Nano Research Energy2022，1，2： | 1 |
| 2 | On high-performance rotational energy harvesting with a novel cam-like dielectric elastomer generator显示文摘Rotational energy is a type of common energy source that can be harvested for supplying low-powered electronic devices.This paper proposes and investigates a novel cam-like dielectric elastomer generator(CDEG)for high-performance rotational energy harvesting.A mushroom-head clamp is designed to form a type of advanced conical dielectric elastomer membranes(DEMs).Moreover,a type of multi-protrusion cam mechanism is designed in the CDEG to effectively convert any external rotational excitation into a linear reciprocating motion,which can be further converted into electricity through the DEMs.First,the operating principle of the system under external rotational excitation is analyzed theoretically by deducing the deformation condition of the DEMs and the electrical output of the system.Second,the prototype is fabricated,and the rotational-to-linear motion conversion rule of its cam-like mechanism and the DEM capacitance calculation approach are validated.The experimental results show that adequate charging time and discharging time of the DEMs,which can be realized through the proposed cam-like mechanisms,are beneficial to the energy harvesting(EH)performance of the system.Third,with the validated theoretical model,numerical simulations are conducted to further study the system dynamics and the influences of important system parameters on the EH performance to provide a guideline for system improvement.Finally,the genetic algorithm is adopted to obtain the optimal system parameters and the corresponding electrical output of the proposed CDEG,demonstrating its superior output power at ultralow rotational frequencies compared with other typical rotational energy harvesters in the literature. | FANG ShiTong WANG ShuaiBo ZHANG GuoQing WANG Chen XU JunChen WANG ZhouZhou FENG AiJie QIAO ZiJian YURCHENKO Daniil LAI ZhiHui | 2023 | Science China(Technological Sciences)2023，66，5： | 0 |

| 4 | Single mode fiber dislocation Mach-Zehnder interferometer cascaded with fiber Bragg grating for monitoring metal electrochemical corrosion显示文摘An optical fiber sensor composed of a dislocation Mach-Zehnder interferometer(MZI) cascaded with a fiber Bragg grating(FBG) is proposed,and it is used to monitor the electrochemical corrosion of metals in experiments.The dislocation interferometer is composed of two segments of single-mode fiber(SMF) and one segment of dislocation SMF.The contact surface is increased between the fiber and the environment,which helps to improve the interference sensitivity.The relationship between the dislocation amount and the refractive index sensitivity of the interferometer is discussed through simulation.In the experiment,the sensitivity of the interferometer reaches more than 10 000 nm/RIU,and the monitoring of metal electrochemical corrosion is also realized in 3.5% NaCl solution.The proposed measurement scheme has the advantages of small structure,low cost and high sensitivity.It has good prospects in chemical reaction monitoring. | ZHANG Shuaibo LIU Xiaoqi WANG Zhi LIU Yange | 2023 | Optoelectronics Letters2023，19，11： | 0 |
