So osmosis, as I understand it, is the balancing of some substance on both sides of an opening. Like, if there is and abundance of salt on one side of the opening but a lesser amount on the other side, the salt will end up in an even amount in both chambers. Less in the chamber that had more, and more in the chamber that had less. I understand what you are talking about in your post. Current goes from negative to positive, and the greater the difference in the positive negative gap the greater the power. And I get that ions have a charge, but you said that the lattice was neutral, so I didn't understand.

Thanks for your reply. What do you mean by electrical netrality of the lattice? What do you mean by orbital? "[metallic bonds] This form of bonding delocalises the bonds" What are metallic bonds, and it delocalises what bonds?

It looks like I may have been wrong about electrons flowing from the battery to the p region, but what really happens is holes flow from the p region to the battery. I don't understand why that would be happening though.

So I get that if you hook the "positive" side of the battery up to the part of the silicon doped with negative ions, that electrons will flow from the battery into that region. What I don't get is why the electrons are pulled into the neutral zone between the p and n type silicone, making the gap wider. What principle is pulling the electrons to the neutral zone?
