A homojunction is a semiconductor interface that occurs between layers of similar semiconductor material, these materials have equal band gaps but typically have different doping (semiconductor). In most practical cases a homojunction occurs at the interface between an n-type (donor doped) and p-type (acceptor doped) semiconductor such as silicon, this is called a pn junction. This doesn't have to be the case though, the only requirement is that the same semiconductor (same band gap) is found on both sides of the junction, in contrast to a heterojunction.
