Depends, what does ELI5 mean? When an electron, seated at the edge of a crowded-with-electrons valence band in a semiconductor, gets excited and jumps

Depends, what does ELI5 mean? 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. So, it is something else entirely, after this whole process completes. It is transformed from being an electron, and is no longer an electron. Electrons are Leptons, not Bosons. The electron is transformed into a different thing, after it jumps out of its hole, only to land back in the hole it jumped out of. When they made an electron jump out of it's valence shell, and then permitted it to bounce back into the void it left behind, landing back in the slot changes it enough that it's no longer an electron. Apparently the orbit it resumes is different enough to be detected with instrumentation, which actually is pretty interesting, and probably matters in terms of optimizing materials for solid-state applications. I can't tell if it's just that these are temporary ripples in the valence field that eventually resolve themselves, and that it's just a mild technicality, to be able to notice that the jumping electrons don't immediately meld back into their cloud, and that on paper, and due to mathematical descriptions, this "qualifies" the rebounded electron as "no-longer-an-electron" until it resumes a normal harmonious "orbit" with the atom's general electron cloud? (AKA: "decays back into an electron" in technical terms) How does this kind of boson transition back to an ordinary electron? How long does that take? How often does this happen in nature? What does this mean in the grand scheme of things? Is the entire world, nay, universe, slowly and irrevocably transforming all electrons into these things forever? How come the all the world's electrons haven't completely decayed into these sorts of bosons by now? Is this really very significant, or is it just a tidbit of technical trivia that persists for less than a few units of planck time? The article does not answer such questions.
