Assignment Help:

It is based on the principle that conductivity of a semiconductor enhances with increase in the intensity of incident light.

In this, a thin layer of some semiconductor (as selenium) is placed below a transparent foil of some metal. This combination is fixed over an iron plate. When wave is incident on the transparent foil, the electrical resistance of the semiconductor layer is changed. As a light starts flowing in the battery circuit linked.
