Speech Title: Intelligent Resource Allocation in Mobile Edge Computing

Abstract: With the increasing popularity of resource-intensive mobile applications, offloading computationally expensive tasks to the edge nodes such as base stations and access points will be a key feature of Mobile Edge Computing (MEC) networks. However, compared to the classical remote cloud, these edge nodes are typically equipped with low-power computational resources with limited computational capability. Therefore, efficient computation offloading systems need to be designed where the servers are efficiently utilized while fulfilling the users' latency constraints. In this talk, we focus on the challenges of mobility and energy constraints at edge nodes, constructing UAV-enabled MEC model and WPT enabled MEC model. We propose intelligent optimization methods based on reinforcement learning to optimize task allocation and computation offloading jointly in both offline and online task scenarios, reducing task computation latency and meeting users' quality of experience (QoE) requirements.

Speech Title: Preparation of large-area perovskite solar cells

Abstract: Perovskite solar cells have become the most promising new generation of photovoltaic technology due to their high efficiency, low cost, and ease of preparation. Although the efficiency of perovskite solar cells has exceeded 26.1%, which is comparable to that of crystalline silicon, their stability and device scaling still face challenges, which has seriously delayed their industrialization process. Among them, perovskite materials based on the formamidinium system are more stable than those based on the methylammonium system, but their large-area scaling is particularly difficult, mainly because the nucleation and crystallization are difficult to control. In this report, we mainly discuss the nucleation and crystallization mechanism of perovskites and control strategies. By adjusting the ink through solvent and additive engineering, and adopting coating methods such as spin coating, blade coating, and slot-die coating, we have achieved the preparation of large-area high-quality perovskite thin films.

Speech Title: Low toxicity luminescent quantum dots and electroluminescent devices

Abstract: It is challenging to pursue brighter and more efficient light-emitting diodes (LEDs) based on the low toxicity quantum dots. We synthesized a series of Carbon Dots (CD) and two dimensional lead-free perovskite, which can emit efficient visible light. Using these as-prepared luminescent materials as emiting layer, CBP or PVK as hole transport material, the LED devices was prepared. Especively, we doped ZnMgO electron transport layer with polyvinyl pyrrolidone, achieving a meticulous moderation in the carrier transport rate. This intricate balance ensures optimal interaction between hole and electron injections. As a result of our comprehensive research and innovative interventions, the optimized LED device radiated with an extraordinary brightness of 505 cd m-2, combined with a low turn-on voltage of 2.5 eV. This development undeniably marks a significant milestone in the evolution of all solution CD devices.
