Course description and aims
[Summary of the lecture] This course focuses on the charge separation initiated from the photo-excited state of a molecule formed through the light absorption and its application to photo-energy conversion devices. Understanding of the interaction of light with substances is essential for developing the phot-energy storage technologies. Emphasis is placed on the common concept of control of the relaxation of photo-excited states for both photocatalysis and photovoltaics.
[Aim of the lecture] Systems enabling to efficiently convert solar light to chemical or electric energy are critical for replacing the present energy resources such as petroleum and nuclear power with renewable energy resources. Students will have the chance to have a look at a scenario for solving energy problems using conversion technology of solar light so that they will be able to discuss the related matters by their own words.
Student learning outcomes
At the end of this course students will be able to
(1) explain the initial process which the excited molecule undergoes.
(2) explain the light absorption of a semiconductor and its relaxation process.
(3) explain the photoinduce electron transfer in the molecular systems or smiconductors.
(4) explain the working mechanisms and features of photocatalysis and solar cells.
Keywords
Inorganic semiconductor, Photo-induced charge separation, Photocatalysis, Artificial photosynthesis
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | ✔ Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
(1) At the beginning of each class, important items explained in the previous class are reviewed.
