Vedclass · Answer

(B) In a semiconductor,the energy gap between the valence band and the conduction band is small. When light (photons) falls on the semiconductor,the electrons in the valence band absorb energy and jump to the conduction band. This process increases the number of free charge carriers (electrons and holes),which leads to an increase in the electrical conductivity of the semiconductor.
