Halfway through my animation I slightly changed my topic from "Solar panels" to "Solar cell efficiency".
Originally I had an idea of a stadium, or a theatre of some sort, and electrons jumping from one seat to another because someone had moved to go somewhere. After I changed that we made it more realistic with electrons jumping across from one bar that said "Negative" to one bar that said "Positive".
To make the animation about solar cells, I had to learn about other things like voltage, current and electricity, which I only knew some about at the start of the animation.
I figured out that the solar panels are dark because, if they’re not, the light bounces off and when it’s dark it gets absorbed so the energy isn’t wasted.
In real life the band gap energy doesn’t mean that the negative and positive sides are further apart (like it looks like in the animation) but that was a good way to show it so that people would understand.
My topic was so complicated that, although it’s still the longest, we had to remove some of the information that we were going to include at the start.
