PhotoElectric
Light of certain Energy shines on some material generates Electricity. This effect is called PhotoElectric
 * hf = hfo + $$\frac{1}{2}m v^2$$
 * f > fo for v > 0

Photon Light of Quantum Energy E = hf has the capability to generate Electricity when shines on Light conducting materials  consists
 * 1) Visible Light
 * 2) UVF Light
 * 3) X Ray
 * 4) Gamma Ray
