If you would love a way to increase the efficiency of solar panels by more than 20%.

That's the problem with solar panels. They're so inefficient by at least 20%.

Josh Cheng Huang is on a team at Northwestern University that is figured out a way to increase

the efficiency of solar panels more than 20%.

So Dr. Huang, what did you use to do that?

Well, we use some Blu-ray movie discs.

A Blu-ray movie disc.

A very old probably in 1992 Jackie Chan movie. It was called Police Story Number Three, Super Cop.

Super Cop?

Super Cop?

Super Cop, yes.

Now, is there a reason you chose this movie?

My graduate student Alex Smith, he probably did a little Black Friday shopping at Best Buy,

and he discovered a bunch of bargaining movies over there and then Supercop.

So he bought a number of them back to the lab and while we were looking at the movies,

well not watching just looking looking at a disk,

I realized that, you know, I might actually have watched that movie, you know, 10, 20 years ago.

So we decided to start with that one.

And is there anything in particular about that movie?

That really. Eventually we figure out that the movie

content doesn't really matter as long as it's written by Blu-ray standard and also you know it's a

super-car is pretty fun and exciting that could make our research fun
