This lesson has made me relearn some of the principles I thought I knew.

This is a well detailed course. The chemistry behind the working principle of semi conductors is quite complex and this course gives insight to people who have knowledge in chemistry. If you are a beginner, you would have to review this course 2 or more times which is fine. Personally this course was really good. I enjoyed the semiconductor break down. An upgrade on the picture quality would be welcome

A lot of information were given. This course was quite hard for me because of the Chemistry aspect so I had to review the lessons over and over and over again before attempting the quiz and thank God I scaled it in one trial. The intro part of the lessons were clear and easy to understand but as I went further it wasn\'t so clear anymore. I would appreciate it if it can be broken down a bit more to make it easier to grasp. Thank you.

Great lecture, very rich in solar resources. I really enjoyed. 5*!
