Direct-bonded four-junction Ga As solar cells

Journal of Semiconductors 2015年第6期36卷 89-92页

作者：沈静曼孙利杰陈开建张玮王训春 Center for Photovoltaic Engineering Shanghai Institute of Space Power Sources

Direct wafer bonding technology is able to integrate two smooth wafers and thus can be used in fab- ricating III-V multijunction solar cells with lattice mismatch. In order to monolithically interconnect between the GalnP/GaAs and InGaAsP/InGaAs subcells, the bonded GaAs/InP heterojunction must be a highly conductive ohmic junction or a tunnel junction. Three types of bonding interfaces were designed by tuning the conduction type and doping elements of GaAs and InP. The electrical properties of p-GaAs （Zn doped）/n-InP （Si doped）, p- GaAs （C doped）/n-InP （Si doped） and n-GaAs （Si doped）/n-InP （Si doped） bonded heterojunctions were analyzed from the I-V characteristics. The wafer bonding process was investigated by improving the quality of the sample surface and optimizing the bonding parameters such as bonding temperature, bonding pressure, bonding time and so on. Finally, GalnP/GaAs/InGaAsP/lnGaAs 4-junction solar cells have been prepared by a direct wafer bonding technique with the high efficiency of 34.14% at the AM0 condition （1 Sun）.

High-quality quasi-monochromatic near-field radiative heat transfer designed by adaptive hybrid Bayesian optimization

引用

Science China(Technological Sciences) 2022年第12期65卷 2910-2920页

作者： ZHANG WenBin WANG BoXiang XU JianMing ZHAO ChangYing institute of Engineering Thermophysics MOE Key Laboratory for Power Machinery and EngineeringSchool of Mechanical EngineeringShanghai Jiao Tong UniversityShanghai 200240China State Key Laboratory of space power-sources Technology Shanghai Institute of Space Power-SourcesShanghai 200245China

The increasing demand for versatile and high-quality near-field radiative heat transfer(NFRHT) has created a critical need for a design approach that can handle numerous candidate structures. In this work, we employ and develop an adaptive hybrid Bayesian optimization(AHBO) algorithm to design the high-quality quasi-monochromatic NFRHT. The candidate materials include hexagonal boron nitride, silicon carbide, and doped silicon. The high-quality quasi-monochromatic NFRHT is optimized over 1.0 × 10^(8) candidate structures to maximize the evaluation factor. It is worth noting that only 2.6% of the candidate structures needed to be calculated to identify the optimal structure. The optimal structure of quasi-monochromatic NFRHT is an aperiodic multilayer metamaterial that differs from conventional periodic multilayer structures. Moreover, we investigate the robustness and mechanisms of the optimal quasi-monochromatic NFRHT with respect to the vacuum gap distance and the temperature difference between the emitter and receiver. In addition, the high-quality multi-peak NFRHT is designed using the AHBO algorithm by improving the definition of the evaluation factor. The results demonstrate that the AHBO algorithm is efficient in designing high-quality quasi-monochromatic and multi-peak NFRHT, and it can be further expanded to other structural designs in the field of energy conversion.

Preparation and Characterization of the Zr/CuO Pyrotechnical Battery

Journal of Wuhan University of Technology(Materials Science) 2012年第3期27卷 489-494页

作者：赵保国赵林双 State Key Laboratory of Explosion Science and Technology Beijing Institute of Technology shanghai institute of space power-sources

A pyrotechnical battery is successfully prepared, including an anode and cathode having pyrotechnic charges with Zr, CuO and asbestos. The anode and cathode are separated by a separator formed from LiF, ZrO2, and a fibrous sponge. A digital phosphor oscilloscope （DPO） is used to analyze discharge characterization of the pyrotechnical battery. Then the properties of the electrode materials are characterized by EDS, SEM and a temperature recorder, respectively. The discharge mechanism and safety characteristic are also discussed. The results indicate that the combustion temperature of electrode materials is determined as 1 500.6 ℃ according to thermometry analysis （the case temperature of the battery is lower）. The combustion product is identified as ZrO2, Cu2O and Cu by X-ray diffraction （XRD）. When the diaphragm is completely melted, Li＋ migration and an embedded-based conductive process are formed. Then an electromotive force will immediately reach to the maximum. The discharge performance of the pyrotechnical battery then takes on stability. The electromotive force is up to 2.29 V, and that discharge time continues for more than 18 s. The current density in the small area （less than 2.88 Acm-2） is most effective. The conversion efficiency of electric energy is 96%. The pyrotechnical battery is very safe for the production and use processes.

Structure adapting of bulk FeS_(2) micron particles and the corresponding anode for high performance sodium-ion batteries

引用

Journal of Materiomics 2022年第6期8卷 1278-1286页

作者： Yong Li Daixin Ye Wen Liu Rui Guo Haijuan Pei Hongbing Zhao Jiujun Zhang Jingying Xie Jilie Kong State Key Laboratory of space power-sources Technology Shanghai Institute of Space Power SourcesShanghai200245China Department of Chemistry Fudan UniversityShanghai200433China institute for Sustainable Energy/College of Sciences Shanghai UniversityShanghai200444China

The practical application of Pyrite iron disulfide (FeS_(2)) as anode material of sodium-ion battery is limitedby its low electronic conductivity, large volume changes during charge/discharge. To overcome thesechallenges, a novel structure design single-walled carbon nanotubes (SWCNTs) composited polyaniline(PANI)-wrapped FeS_(2) (FeS_(2)-PANI-SWCNTs) electrodes are successfully achieved in this work. PANI canprotect the FeS_(2) particles from collapse and offer a protective layer to relive the polysulfides shuttlingeffect, and also promote the electron and Naþ diffusion during the chemical conversion process. Underthe dual protection of PANI and SWCNTs, the FeS_(2)-PANI-SWCNTs film electrode demonstrates a goodstructural integrity, which accounts for the excellent rate capability and long cycling performance. Inaddition, the PANI coating and SWCNT network in the fabricated electrode can synergistically anchorpolysulfides and therefore strongly suppress shuttle effect during the chargeedischarge processes,resulting in less capacity loss. The anode with a loading 3.2 mg cm 2 of FeS_(2) coated with PANI exhibitsthe initial coulombic efficiency of 81.5% and delivers a specific capacity of 625.8 mAh g^(-1) after 100 cyclesat 200 mA g^(-1). High flexible and binder-free FeS_(2)-PANI-SWCNTs film anode demonstrates a reversiblecapacity of 537 mAh g^(-1) after 550 cycles at 1 A g^(-1). This research may offer an efficient method toimprove electrochemical performance of the metal sulfides in sodium-ion batteries.
