Recombination is the process in which Electrons and Holes combined together and neutralizes their effect.

I am not getting this. Someone help me to get it.

Electron loose its energy by moving from conduction band to valance band, and in valance band only holes can occupy and this process is known as recombination.

The recombination process occurs when an electron falls into a hole generating current.

When temperature is increased, valence electrons break covalent bond and move to the conduction band.

The recombination occurs only in lower energy level that is in valence band. So electron fall from conduction band combine with holes in valence band i.e. recombination.

Free electrons fall into covalent bond resulting in the loss of pair of mobile carriers.

Recombination is the process of combining hole and electron then they will be disappear.

In the recombination process electron disapeared in hole and some loss would be happen.
