Sure, most people know that you can produce electricity with photovoltaic (PV) panels. But have you ever wondered exactly how solar cells generate electricity?

There’s a great, very detailed explanation of the whole process on the How Stuff Works website.

Or, here’s another idea. You can skip the article and jump straight to this solar cell quiz (also from How Stuff Works). You can learn a lot just by guessing, because the quiz format explains the answer right after each question.

If you're brave enough to share your quiz score (and whether or not you read the article) post it in the comments section below. My quiz score was 7/10 after reading the article. Think you can beat that? Go ahead, give it your best shot!
