In this work, gold nanoparticles (AuNPs) with high electrical conductivity were added in different weight fractions (up to 1 wt%) into the epoxy matrix of CFRP electrodes used in graphene oxide-bearing SDCs (GO/SDCs). The electrical conductivity of AuNP-modified CFRP electrodes was 15–250% higher than the unmodified CFRP electrode, depending on the concentration of nanoparticles. As a result, both specific capacitance and energy storage density of AuNPs-modified GO/SDCs were higher (up to ~170% and ~50%, respectively) than the unmodified GO/SDC. Furthermore, AuNP-modified GO/SDCs had higher tensile and interlaminar shear properties. This research provides new insights into improving both the electrical and mechanical properties of SDCs using AuNPs.

Huihui Zhang’s paper, Ultrahigh heating rate induced micro-explosive production of graphene for energy storage, has been accepted by Journal of Power Sources. Dan Yang and Chong Lei are listed as co-authors. Baohua and Han are the corresponding authors [LINK].
In this work, by introducing ultrahigh heating rate into thermally driven reduction process and ensuring a high local temperature via thermal management, the authors propose the production of such materials through micro-explosive reduction process initiated by short heating pulses, for example using a camera flash. This simple and scalable method enables rapid gas generation and release process and creates sponge-like electrode materials with high ion-transportation quality. Electrochemical supercapacitors based on the fabricated electrodes demonstrate high energy density of around 60 Wh kg−1.

Yunyi Yang’s paper, Graphene Oxide Waveguide and Micro‐Ring Resonator Polarizers, has been accepted by Laser & Photonics Reviews. Jiayang Wu is listed as co-first author, Yang Qu, Xingyuan Xu, Yao Liang, Sai Tak Chu, Brent E Little and Roberto Morandotti are listed as co-authors. Baohua and David Moss are the corresponding authors [LINK].
In this work, detailed measurements are performed to characterize the performance of the devices versus GO film thickness and coating length as a function of polarization, wavelength and power. A high polarization dependent loss of ≈53.8 dB is achieved for the waveguide coated with 2‐mm‐long patterned GO films. It is found that intrinsic film material loss anisotropy dominates the performance for less than 20 layers whereas polarization‐dependent mode overlap dominates for thicker layers. For the MRRs, the GO coating length is reduced to 50 µm, yielding a ≈8.3 dB polarization extinction ratio between transverse electric (TE) and transverse magnetic (TM) resonances. These results offer interesting physical insights and trends of the layered GO films and demonstrate the effectiveness of introducing GO films into photonic‐integrated devices to realize high‐performance polarization selective components.

Zhixing Gan’s paper, Transient Energy Reservoir in 2D Perovskites, has been accepted by Advanced Optical Materials. Chunhua Zhou, Weijian Chen, Fei Zheng, Shuang Yang, Jeffery Davis, Patrick Charles Tapping, Tak W Kee and Hua Zhang are listed as co-authors. Xiaoming and Baohua are the corresponding authors [LINK].
In this work, it is revealed that there is a special transient energy reservoir outcompeting nonradiative loss in 2D Ruddlesden−Popper type perovskites. Upon optical excitation, the bright excitons rapidly relax into the low‐lying energy reservoir before nonradiative recombination occurs. Interestingly, the energy in the reservoir is not lost. The carriers in this energy reservoir can spontaneously transfer back to the bright states and can still effectively contribute to the photovoltaic and photonic properties of the perovskites. This investigation provides a novel insight into the mechanism for the lauded defect tolerance of 2D perovskites by highly efficient energy storage via a transient reservoir.

Zhixing Gan’s paper, The Optical Properties of Cs4PbBr6-CsPbBr3 Perovskite Composites, has been accepted by Nanoscale. Fei Zheng, Wenxin Mao, Chunhua Zhou, Weijian Chen, Udo Bach, Patrick Charles Tapping, Tak W Kee and Jeffery Davis are listed as co-authors. Xiaoming and Baohua are the corresponding authors [LINK].
In this work, green emission of the CsPbBr3-Cs4PbBr6 perovskite composites is studied by the temperature dependent photoluminescence (PL). The PL spectra at different temperatures simultaneously contain two sub-peaks (520 nm and 550 nm), which are ascribed to emissions of band-edge and the defect trapped exciton of CsPbBr3. This finding will help to understand the controversial photoluminescence currently observed in different 0D Cs4PbBr6 perovskites.

Fei Zheng and Weijian Chen’s paper, Triggering the Passivation Effect of Potassium Doping in Mixed-Cation Mixed-Halide Perovskite by Light Illumination, has been accepted by Advanced Energy Materials. Tongle, Kenneth, Fuzhi, Yibing, Patrick and Tak are listed as co-authors. Xiaoming and Baohua are the corresponding authors [LINK].
In this work, it is demonstrated that illumination is essential to trigger the passivation effect of K+ by forming KBr-like compounds, leading to the elimination of interface trapping defects and suppression of mobile ion migration, thus resulting in improved power conversion efficiency and negligible current-voltage hysteresis of solar cells. This work provides novel insight into the hysteresis suppression upon K+ doping and highlights the significance of light illumination when using this protocol.
Congratulations Fei and Weijian!

Weijian, Chunhua, Shuang, Guiyuan, Kenneth and Ghiggino are listed as co-authors. Xiaoming and Baohua are the corresponding authors.
In this work, a comparison of 3D bulk CH3NH3PbBr3 single crystal to 2D perovskite by depth-resolved two-photon PL spectra reveals the contribution of carrier diffusion on energy transport at a distance beyond diffusion length is constantly negligible, though the carrier diffusion indeed exists in the 3D crystal. The investigation resolves the fundamental confusion and debate surrounding the issue and provides significant insights into carrier kinetics in perovskites, which is important for future developments in solar cells and other optoelectronic devices.

Han Lin’s paper, A 90-nm-thick graphene metamaterial for strong and extremely broadband absorption of unpolarized light, has been accepted by Nature Photonics [Link]. Björn C. P. Sturmberg, Keng-Te, Yunyi, Xiaorui and Teck are listed as co-authors. C. Martijn de Sterke and Baohua are the corresponding authors.
In this work, the authors experimentally dem-onstrate a 12.5 cm2, 90-nm-thick graphene metamaterial with approximately 85% absorptivity of unpolarized, visible and near-infrared light covering almost the entire solar spectrum (300-2,500 nm). The metamaterial consists of alternating graphene and dielectric layers; a grating couples the light into waveguide modes to achieve broadband absorption over incident angles up to 60. The very broad spectral and angular responses of the absorber are ideal for solar thermal applications, as they illustrate by showing heating to 160 C in natural sunlight. These devices open a novel approach to applications of strongly absorbing large-area photonic devices based on two-dimensional materials.

In this study, the authors present an analytical design method for achieving high-order two-dimensional photonic crystals with tunable photonic band gaps on-demand. Based on the Bloch mode analysis for periodic structures, the authors are able to determine the geometric structure of the unit cell that will realize a nearly optimal photonic band gap for one polarization between the appointed adjacent bands. More importantly, this method generates a complete bandgap for all polarizations, with frequencies tuned by the number of photonic bands below the gap. The lowest dielectric contrast needed to generate a photonic band gap, as well as conditions for generating complete bandgaps, are investigated. The work first highlights the systematic approach to complete photonic band gaps design based on Bloch mode analysis. The physical principles behind our work are then generalized to other photonic lattices.

More importantly, the RS design method is able to accurately design GO lenses with arbitrary NA and focal length. Their design is experimentally confirmed by fabricating high NA GO lenses with both short and long focal lengths. Compared with the conventional Fresnel design methods, the differences in ring positions and the resulted focal length are up to 13.9% and 9.1%, respectively. The method can be further applied to design high performance flat lenses of arbitrary materials given the NA and focal length requirements, including metasurfaces or other two-dimensional materials.

Fei Zheng’s paper, Slow Response of Carrier Dynamics in Perovskite Interface upon Illumination, has been accepted by ACS Applied Materials & Interfaces [Link]. Weijian is listed as a co-author. Xiaoming and Baohua are the corresponding authors.
In this study, the authors investigated the slow variation of photogenerated carrier dynamics in (FAPbI3)0.85(MAPbBr3)0.15 perovskite interface under continuous illumination. Different response behaviours of carrier dynamics in perovskite interfaces with and without hole transporting layer, Spiro-OMeTAD (Spiro), were systematically studied by time-dependent steady-state and time-resolved photoluminescence (PL). It was demonstrated that light-induced defect curing process is dominantly responsible for the carrier dynamic evolution for perovskite interface without Spiro, while both defect curing process and mobile ions migration should be account for the dynamic response of perovskite interface contact with Spiro. This research work can faithfully highlight the strong correlation of slow photo-response behaviours of perovskite interface with both light-induced defect curing and ion migration process, providing novel implications into the physical mechanism for the slow variation of PSCs performance under working condition.
Xiaoming’s paper, The Role of Surface Recombination in Halide Perovskite Nanoplatelets, has been accepted by ACS Applied Materials & Interfaces [Link]. Weijian, Tieshan, Chunhua, Han are listed as co-authors. Xiaoming, Baohua and David are the corresponding authors.
The paper, using time-resolved micro-spectroscopy along with modelling, investigates charge carrier recombination dynamics in halide perovskite CH3NH3PbI3 nanoplatelets with thicknesses from ~ 20 – 200nm, ranging from much less to comparable to the carrier diffusion length. It shows that surface recombination plays a stronger role in thin perovskite nanoplatelets, significantly decreasing photoluminescence (PL) efficiency, PL decay lifetime, and photo-stability. This work provides a comprehensive understanding of the role of surface recombination and charge carrier dynamics in thin perovskite platelets and reveals valuable insights useful for applications in photovoltaics and photonics.
