When light falls on a CCD, photons are converted into what?

Explanation:
Light entering a CCD is converted into electrons. When photons are absorbed by the silicon, they create electron-hole pairs, and the electrons are collected in the pixel’s potential well. The number of electrons in each pixel corresponds to the light intensity, forming the image data. Later, those collected electrons are shifted and read out as a voltage signal, but the immediate conversion step is photons turning into electrons.
