Oh woops, I missed the "charge carriers." Basically that middle part is content to not have electrons moving through?

Back to this diagram:

Is it that the sunlight hits the undoped silicon --> an electron now leaves that depletion zone and a hole is created there(?) (this part I'm confused about) and somehow it's the bottom p-type layer that now has a hole, maybe because it moved an electron up to the depletion zone because electrons prefer to move in one direction as the electrons from the N-type layer are attracted to the P-type layer?
Why is it that there are two arrows coming out of the "Photon Absorbed in Depletion Zone Electron-hole Creation"? And..the photon just bypasses the N-layer and goes to the Depletion zone :o?

Metals characteristically lose their outermost electrons very easily, which means there's a free-flowing cloud of electrons inside the metal instead of a rigid electron structure. This is why they conduct heat and electricity so well. Metals are usually malleable (able to be pressed into shapes without breaking), ductile (able to be stretched into wires), and fusible (can be melted together). A nonmetal is anything that doesn't do these things. Metalloids have properties in between, though which elements are metalloids and which aren't isn't completely agreed upon (for example, some classifications say aluminum is a metalloid, most say it's a metal; some say carbon is a metalloid, most say it's a nonmetal).

Ah, woops. I completely forgot that metals were characterized by those traits! I didn't know they were characterized by being fusible though.

Computer chips are the most well-known use of semiconductors.

Unfortunately, I don't even know what a computer chip does nor where it is :/. Um, what is a "chip"?
