Abstract: Many chiral absorbers have been proposed to obtain selective absorption for left circularly polarized (LCP) and right circularly polarized (RCP) waves. However, it is difficult to realize tunable chiral absorbers with strong chiral response for the incidence angle in a wide range. Here we show that strong chiral response can be achieved by using a simple structure composed of a uniaxial slab and a silver grating. The numerical results show that the absorptance of the proposed structure for incidence of LCP wave can be close to unity while the absorptance for incidence of RCP wave can stay close to zero at the resonance wavelength of magnetic polaritons (MPs) in the grating grooves. More importantly, the circular dichroism (CD) of the structure is shown to remain larger than 0.7 for allazimuthal angles and for the incidence angle from 0o up to 30o. In addition, this structure can also be engineered to work in a broadband or indifferent wavelength ranges. Owing to its simple configuration, this device holds promise for polarization-sensitive surface photo chemistry and chiral bolometers.

4. Effiiceiency Optimization in a Microscale Vacuum-gap Thermionic Energy Converter with High Solar Concentration
Yuan Wang, Shanhe Su, Effiiceiency optimization in a microscale vacuum-gap thermionic energy converter with high solar concentration, ES Energy Environ., 2020, 8, 15-20.
DOI: https://dx.doi.org/10.30919/esee8c377
Abstract: The irreversible losses resulting from thermal radiation and the space charges effect have been accepted as the primary mechanisms for vacuum-gap thermal electric converter, which raises the question of how to best combine the two mechanisms to maximize the conversion efficiency. Here, we theoretically analyze the performance of a solar concentrating thermionic energy converter (STEC) with microscale interelectrode space. In the proposed STEC system, both near-field thermal radiation and the space charge effect are considered. By building an energy balance equation, the cathode temperature is determined and numerically solved for given solar irradiance. The influences of the optical concentration, voltage and interelectrode space on the heat flux and conversion efficiency are revealed. It is found that the near-field thermal radiation can be approximated by Stefan-Boltzmann formula with effective emissivity 0.04 for d>1 μm. By interplaying between the two kinds of irreversible losses, the maximum conversion efficiency and the corresponding interelectrode space of STEC are pointed. Our investigation provides an effective mean to optimal design the interelectrode space of the STEC.

5. Experimental Investigation and Numerical Validation on the Energy-Saving Performance of a Passive PCM Floor for a Real Scale Building
Jinming Shi, Xinyu Huang, Huichuan Guo, Xiaodong Shan, Zhilong Xu, Xiaona Zhao, Zhili Sun, Waseem Aftab, Chong Qu, Ruimin Yao, Ruqiang Zou, Experimental investigation and numerical validation on the energy-saving performance of a passive PCM floor for a real scale building, ES Energy Environ., 2020, 8, 21-28.
DOI: https://dx.doi.org/10.30919/esee8c380
Abstract: Phase change material (PCM) can store heat at a constant temperature, which is beneficial to reduce building energy consumption. Herein, we fabricated a PCM board that can store 98-102 J/g heat at 26 °C. The PCM boards were paved as the floor in the real-scale office to reduce power for temperature regulation, which led to the reduced energy consumption of 18.8% and 19.7% in winter and summer, respectively. A numerical model is validated by experimental data to evaluate long-term performance. The experiment and simulation results both demonstrate the high-performance PCM floor for effectiver eduction in electricity consumption of heating and cooling.
6. Full-Spectrum Solar Energy Utilization and Enhanced Solar Energy Harvesting via Photon Anti-Reflection and Scattering Performance Using Nanophotonic Structure
Huaxu Liang, Fuqiang Wang, Ziming Cheng, Chao Xu, Guiqiang Li and Yong Shuai, Full-Spectrum Solar Energy Utilization and Enhanced Solar Energy Harvesting via Photon Anti-Reflection and Scattering Performance Using Nanophotonic Structure, ES Energy Environ., 2020, 8, 29-41.
DOI: https://dx.doi.org/10.30919/esee8c456
Abstract: Conventional Si photovoltaic cells cannot convert full solar energy spectrum (400~2500 nm) intoelectricity owing to the mismatch between Si band gap and broad range of solarphoton energies. Transparentsilicon PV cell allows sunlight in the wavelength of 1100~2500 nm to transmit through itself and irradiate on the thermal absorber below. The traditional photon management method based on texturing silicon layer with nanostructures can enhance 400~1100 nm absorptivity and 1100~2500 nm transmittance of transparent silicon PV cell. However, an increase in charge carrier capture and a decrease in electricity generation efficiency are often observed with this. In this study, a noval spectral splitting method based on front-located wavelength-sized TiO2 moth-eye nanophotonic structure is proposed, which can inhibit the increase of charge carrier capture and recombination. The structure was optimized by using finite-difference time-domain (FDTD) method to achieve excellent photon anti-reflection and scattering properties. The calculation results indicated that the absorption factor and transmission factor of transparent silicon PV cell could be increased from 46% to 58% and from 11% to 14%; the relative power conversion efficiency enhancement rate and relative incident radiation power enhancement rate was 32% and 27% when the TiO2 moth-eye was adopted.

7. Superior Thermal Dissipation in Graphene Electronic Device Through Novel Heat Path by Electron-Phonon Coupling
Abstract: Interfacial thermal resistance (ITR) plays an important role in thermal dissipation across different materials and it has been widely investigated in recent years. In this work, we measured the relative change of the ITR between metal and aluminum oxide treated with O2-plasma. Significant reduction of ITR is observed. The measured data shows that plasma treatment induces an order of magnitude decrease of ITR, which is mainly attributed to the direct electron-phonon coupling across the interface. Scanning thermal microscopy technique measurement of graphene electronic devices on aluminum oxide gave direct evidence for heat dissipation applications by tuning the surface charge carries concentration.

8. Near-field Radiative Thermal Modulation by Tunneling Through Graphene Sheet
Yizhi Hu, Xianglin Tang, Yonggang Zhu and Yue Yang, Near-field Radiative Thermal Modulation by Tunneling Through Graphene Sheet, ES Energy Environ., 2020, 8, 48-55.
DOI: https://dx.doi.org/10.30919/esee8c496
Abstract: In this paper, we have theoretically demonstrated a graphene-mediated near-field radiative thermal modulator based on doped silicon-graphene-doped silicon three-slab configuration. The near-field photon tunneling between the doped silicon emitter and receiver is modulated by changing chemical potential of graphene sheet and the separation distance between the sheet and the emitter. The near-field three-body theory built on fluctuational electrodynamics is used to calculate total radiative heat flux, which could be modulated in a range of 10-70kW/m2 with different setup for graphene chemical potential and its position. The underlying mechanism is illustrated as varied coupling behavior of surface plasmon polaritons between doped silicon and graphene sheet. Several dimensionless factors such as normalized heat flux, sensitivity factor and switching factor are also introduced for comprehensive analysis of the performance of modulation effect. The results obtained here will trigger a newway for near-field active thermal management between bulk materials utilizing suspended 2-D materials.

9. Seeking for Low Thermal Conductivity Atomic Configurations in SiGe Alloys with Bayesian Optimization
Jiahao Yan, Han Wei, Han Xie, Xiaokun Gu, and Hua Bao, Seeking for Low Thermal Conductivity Atomic Configurations in SiGe Alloys with Bayesian Optimization, ES Energy Environ., 2020, 8, 56-64.
Abstract: The emergence of data-driven science has opened up new avenues for understanding the thermophysical properties of materials. For decades, alloys are known to possess very low thermal conductivity, but the extreme thermal conductivity that can be achieved by alloying has never been identified. In this work, we combine the Bayesian optimization with a high throughput thermal conductivity calculation to search for the lowest thermal conductivity atomic configuration of SiGe alloy. It is found layered structures are most beneficial for reducing the thermal conductivity among all atomic configurations, which is attributed to the strong branch-folding effect. Furthermore, the roles of interface roughness and layer thicknesses in producing the lowest thermal conductivity are investigated. Through another comprehensive search using Bayesian optimization, the layered structure with smooth interfaces and optimized layer thickness arrangement is eventually identified as the optimal structure with the lowest thermal conductivity.
