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 has been researched the development of a novel integrated flexible self-powered energy system sponsored by the Asian Office of Aerospace Research and Development (AOARD, Award Number: FA2386-18-1-4075). The objective of the DURIP proposal is to request the Raman microscope-Solar simulator for analysis of integrated energy system of perovskite solar cell and Li-S rechargeable battery, at University of North Texas. The UNT team has been successfully carrying out a set of parallel research project for developing the integrated, flexible self-powered energy system with two major functionalities - high-efficiency planar perovskite solar energy conversion (> 20% efficiency) and 2D Li-S rechargeable battery (> 500 Wh/kg and 1,000 cycles). The addition of the proposed system will enable researchers to study in advanced energy storages by synthesizing new materials and understanding new functions of 2D TMDs and perovskite with phase change or stack of layered materials.
