Dr. Cheng’s group has developed electrowetting-controlled liquid prisms for active solar tracking and adaptive sunlight steering without mechanical moving parts. In comparison with traditional silicon-based photovoltaic (PV) solar cells, the electrowetting-based self-tracking technology will generate 70% more green energy with a 50% cost reduction.
Researchers in PACCAR Technology Institute investigated the Organic Rankine Cycle (ORC) integrated with solar energy. The working fluids were studied to meet the specific range of temperatures desired for solar collectors of different configurations. Particular focuses were placed for hot and humid climates and the applications in a building or community scale. Researchers also collected data from 8 buildings in Florida on the effectiveness of geothermal heat pumps in hot and humid climate and anlyzed the results through both modeling and data validation. In addition, wind turbine systems installed on UNT campus have been analyzed through combined data collection and model simulation to access the real-time performance.
