What happens to the photons that reach the sensor in our Cameras?

Question

I know that a picture to appear, light has to reach the individual sensors of a camera.

But what happens when those photons reach the camera sensor? Do they stay there and accumulate? Or do they pass through everything?

Answer 1

They are a form of energy. This energy is used to excite an electron and make it get freed from its binding to an atom. This flowing electron is then the electricity that is the electrical signal that makes up the picture.
