There are various types of energy such as heat, chemical, electrical and nuclear energy and so on, and present human society is built upon the technologies of transportation and the usage of electrical energy. Therefore, we should convert from primary energy to electrical energy using various energy conversion devices to supply society. Energy conversion devices such as electrical generators using thermal energy, heat pumps, electrical generators using nuclear power, fuel cells, solar cells, light emitting devices, and batteries allow us to supply electrical power on demand as well as to store energy. The conversion efficiency of these devices is governed not only by thermodynamics but also by many technical limitations. Therefore, understanding the energy conversion devices is of great importance in order to create a sustainable society from the viewpoint of energy supply. Students learn the basics of energy devices including fundamental operating mechanisms, advantages and disadvantages of technology, and state-of-the-art devices through Interdisciplinary Principles of Energy Devices 1 and 2. This course focuses on photoelectric conversion (light energy/electrical energy) and chemical energy/electrical energy. Operating principles and features of fuel cells, solar cells, light emitting devices, and batteries will be explained. Working mechanisms of these energy conversion devices facilitate students’ understanding of photoelectric conversion and electrochemistry as well as related technologies.
By the end of this course, students will be able to:
1. Explain the basics of fuel cells.
2. Explain the basics of solar cells.
3. Explain the basics of light emitting devices.
4. Explain the basics of batteries.
5. Explain the similarities and differences among these devices.
