Evaluate Unit/Design Process Further
Questions/Discussion
• Further Extensions:
– How do fuel cells compare to solar cells?– Do they yield better efficiencies?– What about other alternative energy cells?– Maybe wind energy?– How do they work?– What is the power in and power out?– How efficient are they? How costly?– What can be done to improve efficiency???
Solar Cells : STEM Topic
• Further Questions:
– Are there other types of Solar Cells (multiple layer, thin film, plastic/organic)?
– How can efficiencies be improved?– How do different types of materials (compound
semiconductors/direct band gap) alter Solar Cell efficiency?
– Are there applications for Solar Cells to recover light in business/manufacturing environments?
Solar Cells : STEM Topic
• Solar Cells– Current-Voltage Charateristics
• PEM Fuel Cells– Electrolyzer Characteristics/Efficiency– Power Supply Characteristics/Efficiency
• Wind Turbines– Power Output vs Blades (Number & Airfoil Selection)– Power Output vs Blade Pitch
• Robotic Control Systems– Solar Cells– Magnetic Fields– Light Intensity– Force – Temperature
