Where does the spin come from that lets the combination of the electron and hole to behave as a boson?

Its quit possible the electron was bound magnetically to a poistron which can nor be measured in the pairing by its smaller mass charge in a electron combination as such do to the larger electron charge mass the seperation of this construction left the hole in which the position still magnetically bound in the electron chain in the conductor attracts an electron to fill the void on the position bound magnetic position

A line of electrons would repel each other a line of electron positron electron positron electron that you could not measure because the position is a minority particle mass charge in the chain of moving current of electrons, when you remove an electron from the chain of electron current leaves two positrons repelling each other you alleged hole in the chain

Good question, @Steve.

Electrons are fermions and have spin +/- 1/2. Having spin 1/2 is the definition of a fermion. Quantum particles have intrinsic spins, for reasons that have to do with Special Relativity; the explanation of why is quite complex, but if you want to push further into this just ask and I'll see if I can try to explain it for you.

Because of the spin of the electron, a place where an electron should be, but isn't, called a "hole," has spin 1/2 too. In semiconductors, like the titanium diselenide used in this experiment, holes behave like they're real particles, and they're not unique. Plasmons and phonons behave like they're particles too, and are even more esoteric than holes. I can explain those for you, but it's even more difficult than showing how spin is a consequence of SRT; but again, ask, and I'll see what I can do.

So with a pair of spin 1/2 particles, there are two possibilities: they are equal or opposite.
[contd]

[contd]
If they are equal, either +1/2 or -1/2, then you get a composite spin 1 particle, and that's a boson because bosons have integer spins. If they're opposite, then you get spin 0, which is also a boson.

So the direct answer to your question, where does the spin come from, is that it's intrinsic to the particles. It's like asking where a particle's mass, or its charge, "comes from." It's just there. That's how particles are. But I think the above is a bit better answer than that for you.

It defies reason, but it turns out that when an electron, seated at the edge of a crowded-with-electrons valence band in a semiconductor, gets excited and jumps over the energy gap to the otherwise empty conduction band, it leaves behind a "hole" in the valence band. That hole behaves as though it were a particle with positive charge, and it attracts the escaped electron. When the escaped electron with its negative charge, pairs up with the hole, the two remarkably form a composite particle, a boson—an exciton.

"It defies reason"? To who? All of this is perfectly reasonable and expected.

Wow time for sexitonium.

On topic tho, there are more ways that one to produce materials that dont belong to our universe

If they can be produced, they belong...
and... sexitonium is the boson produced when "Led Zeppelin" or "Lords of Acid" (or any host of others) fire up their guitars...
