?? Thrilled to Announce Our Latest Publication in Battery Energy! ?? Our study, "Tuning the Electronic and Optical Properties of Cu?ZnSn???Ge?S? Alloys for Photovoltaic Applications: A Hybrid Density Functional Theory and Device Simulation Approach", is now published in Battery Energy, a Q1 journal with an Impact Factor (IF) of 9! ?? What sets this research apart? We combined hybrid density functional theory (DFT) with SCAPS-1D device simulations to explore how Ge-alloying in Cu?ZnSnS? enhances its electronic and optical properties. This innovative approach bridges the gap between material discovery and practical device performance. ?? Key Highlights: Band gap engineering with Ge alloying enables tunable properties for photovoltaic applications. Device simulations reveal enhanced solar cell efficiency with optimal absorber thickness and back-surface field (BSF) layers. Strong light-harvesting capabilities and efficient carrier transport position these materials as next-generation solutions for tandem and multi-junction solar cells.

I am delighted to share that my first paper, titled “An innovative solar reactor with Gaussian-pattern geometry for syngas production from dry reforming of methane,” has been published in the Proceedings of the IMechE, Part C: Journal of Mechanical Engineering Science. This research is accessible online from Sage Publication and you can access my research here: https://lnkd.in/dcnsQgcu In this numerical study, we investigated the performance of a novel foam-based solar reactor design using ANSYS Fluent and programming User-Defined Functions (UDFs). By introducing a Gaussian-pattern geometry inspired by the Gaussian distribution of solar flux, we enhanced energy storage efficiency, temperature distribution, and the uniformity of reaction rates. We simulated the process using the Finite Volume Method (FVM) and the Local Thermal Non-equilibrium (LTNE) approach. This innovative design facilitated improved heat transfer and optimized the utilization of solar energy to enhance the chemical reaction process. I appreciate the valuable feedback and suggestions that contributed to this work and look forward to further research opportunities. #MechanicalEngineering #NumericalSimulation #CFD #RenewableEnergy #MethaneReforming #ResearchPublication #SyngasProduction #Hydrogen

LONGi Solar has broken it's own efficiency world record for a Perovskite-Silicon tandem solar cell with a verified efficiency of 34.6%. Congratulations to all our colleagues on the R&D team. They improved on their previous record of 33.9% set in late 2023 "by optimizing the thin film deposition process of the electron transport layer, developing and using high-efficiency defect passivation materials, and designing and developing high-quality interfacial passivation structures" We know a thing or two about optimizing solar cells, which you can watch here: https://lnkd.in/gUEDDgGa Bo He

During my master's degree, I delved into the fascinating world of Multiphase Superconducting Machines. This research culminated in a paper comparing four Multiphase Superconducting Generator topologies for Wind Power Plants. Our findings were remarkable: ?? A 13-phase machine demonstrated a 34% improvement in torque density compared to a traditional 3-phase machine. ?? We achieved a theoretical torque density of 101 Nm/kg - a significant leap forward in the field. Recently, I came across an intriguing DOE research article titled "Double-Rotor Flux Switching Machine with HTS Field Coils and Superconducting Shields for Aircraft Propulsion". Their results are equally impressive: ?? They report achieving a torque density of 192 Nm/kg (100 kW/kg for 5000 RPM). This discovery has sparked my curiosity: What potential improvements could we see by applying multiphase topologies to these Double-Rotor Flux Switching Machines with HTS Field Coils? How might this impact not only wind power generation but also aircraft propulsion? I'm eager to explore this further and would love to hear thoughts from fellow researchers and industry professionals. What's your take on the future of multiphase superconducting machines in various applications? ?? References: 1.
