Charge Transport in Two-Dimensional Materials Based Integrated Flexible Energy System
Abstract
Solar powered unmanned aerial vehicles (UAVs) require a system capable of long endurance flight without much maintenance. The continuous storing of solar energy in electrochemical devices, such as rechargeable lithium batteries, provides an attractive approach to meet this goal. Although direct integration of a photovoltaic cell and battery into one device with the dual function of conversion and storage of solar energy to electricity has recently been attempted, these systems exhibit low storage capacity that is inadequate for self-powered UAVs for long-term operation. To solve the issue, the PI team and team have researched the development of a novel integrated flexible self-powered energy system sponsored by the Asian Office of Aerospace Research and Development (AOARD). In this proposal, we request the Raman microscope-Solar simulator for analysis of charge transport of 2D materials and integrated energy systems of perovskite solar cells and Li-S rechargeable battery. The addition of the proposed system will enable researchers to study advanced energy storages of synthesized new materials and new functions of 2D transition metal dichalcogenides (TMDs). This research will build the foundation for basic mechanisms of high charge transport in a new class of 2D TMDs materials, which will profoundly impact the fundamental limits on current Li-S rechargeable batteries and perovskite solar cells. The scientific and technological findings of this research will inspire a series of future studies on 2D TMDs and advanced energy storage systems. The University of North Texas, a Hispanic-Serving Institutions (HSI), has invested heavily to promote advanced manufacturing and materials research and education, which is manifested by various activities such as establishing a Materials Research Facility (MRF), Advanced Materials and Manufacturing Processes Institute (AMMPI), and Center for Agile and Adaptive Additive Manufacturing (CAAAM). The establishment of the proposed facility will significantly enhance the undergraduate and graduate education and research training in an integrative and interdisciplinary manner. The proposed efforts will diversify the workforce, encourage students to pursue advanced energy materials and energy systems, and its related career paths, and create new research and teaching opportunities for students in north Texas.
