A few questions that P9810B should help you out to answer...

  • Why amorphous silicon has a larger "optical band gap" than crystalline silicon?
  • Does amorphous germanium have a larger "optical band gap" than crystalline germanium?
  • Are the optical properties of micro-crystalline silicon closer to their crystalline or amorphous counterpart?
  • What is so special in the optical properties of organic photovoltaic materials?
  • Is amorphous silicon absorbing more or less yellow light than crystalline silicon?
  • What parameters determine the performance of a solar cell?
  • What types of solar cells (crystalline/amorphous and/or organic) have a performance that degradates under illumination, and how can this be mitigated?
  • Why amorphous/nanocrystalline/organic solar cells require a transparent electrode while crystalline solar cells do not?
  • Why solar cells on plastics are so attractive and why such goal is so challenging?
  • Why is the architecture of organic solar cells so different from their inorganic counterparts?
  • Provided that solar cells generate an electrical current from absorption of light and Light-Emitting Devices generate light from an electrical current, can a solar cell be reversed and work as a LED, and vice-versa?

If you answered to these questions, there should be no need for you to take this course. If you feel that answering to some of these questions may be useful to improve your understanding in Optics and Optical Properties of Materials, or helpful to develop your research project, you may want to consider taking this course.

If you are interested to the answers, but you are not a Graduate student, or you are a Grad student who has no time to take this course, try sending me an e-mail.
