In other regions , the energy and force maps are more complicated than those in repulsive region due to the effects of the many body interactions and nonspherical distribution of the electrons of the atoms in crystal . When EM radiation impinges upon a conductor , it couples to the conductor , travels along it , and induces an electric current on the surface of that conductor by exciting the electrons of the conducting material . When the x-rays enter the sample , the electrons inside the sample absorb the x-rays and are ejected out of their original positions . How PV cells workThe possibility of producing electrical energy directly from sunlight is based on some properties of semiconductor materials , and particularly on the interaction occurring in certain solid materials between photons ( light packets or " quanta " ) and the electrons of the solid-state atomic matrix . Traveling through matter , light waves interact with the electrons of the material . By looking at how electrons are transferred between the electrode and the molecular acceptors , the scientists were surprised to notice that the speed of the electrons inside the bridge reached a limit for small bridges . If they are n't excited enough and are flowing only like water from your garden hose at home , and the electrons inside the school are flowing around the circuits like the high-pressure water in a fire hose , some of the inside school electrons will push out into the solar panels . It does this by collecting the electrons that some bacteria give off when they break down organic matter . These tornadoes act as tweezers , controlling spin and charge in the electrons of the diluted magnetic semiconductor .
