We have valence e

We have valence electrons in the outer orbit of a semiconductor. We have conduction electrons in the conduction band of semiconductor at 300 K. When an electron jumps from the valence band to the conduction band, a hole is created in the valence band at the place from where that electron jumped. There is no such concept of ‘valence holes’ and ‘conduction holes’. A place void of electron is a hole.
