Once the excited electrons absorb enough energy to jump free from the silicon atoms, they can flow independently through the material to produce electricity.
An atom can absorb a photon, or light particle, by boosting one of its electrons to a higher energy, but it's unstable in this state.
In a traditional solar panel, silicon atoms are struck by sunlight and the atoms» outermost electrons absorb energy from some of these wavelengths of sunlight, causing the electrons to get excited.
«The job of the photoanode is to absorb sunlight and then use that energy to oxidize water — essentially splitting apart the H2O molecule and rearranging the atoms to form a fuel.

Part of the kinetic energy of the swirling molecular ions is absorbed by the helium atoms in collisions, and these atoms in turn transfer it to the rotational motion of the ions, thus raising their rotational temperature.
Ordinary atoms can change their energy levels under the right conditions by either absorbing or emitting a photon.
Their subatomic particles collide, and the iron atoms» nuclei split, leaving behind helium nuclei plus a few leftover neutrons and absorbing a lot of energy in the process.
As hydrogen atoms move about in space, they can absorb small amounts of energy, sending the atom's single electron to a higher energy state.

That incoming light is absorbed by hydrogen atoms and converted to heat energy, NASA stated, and this steady conversion of light - to - heat makes the planet appear to be pitch - black to onlookers, the researchers found.
Another reason it takes so long is because iron atoms in the sun's interior absorb — and hold — some of the energy that passes by them.
When atoms absorb another form of energy, which can be in the form of heat or another EMF.
We, too, are made up of atoms that are always emitting and absorbing light and energy.
Vibrational modes in molecules with three or more atoms (H2O, CO2, O3, N2O, CH4, CFCs, HFCs...) include bending motions that are easier to excite and so will absorb and emit lower energy photons which co-incide with the infrared radiation that the Earth emits.
Photons of sufficient energy are absorbed by oxygen molecules and as a result the atoms of the oxygen are «blown» apart.

If the photon's frequency and energy is different by even a little, the atom can not absorb it (this is the basis of quantum theory).
When ozone absorbs ultraviolet light, it splits into O2 and oxygen atoms and also releases heat energy.
Some might argue that the term «re-radiate» should be reserved for cases where a molecule or atom absorbs a photon of a given energy, and later emits a photon of the same energy, as the excited state returns to normalcy.
Fortunately, as depicted in Figure 2 (orange «thermal down surface» arrow), some of this energy does stay in the atmosphere, where it is sent back toward Earth by clouds, released by clouds as they condense to form rain or snow, or absorbed by atmospheric gases composed of three or more atoms, such as water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4).
The actual resonant frequencies of resonant molecules is affected by pressure; this means more collisions between atoms, and sometimes vibrational energy can be absorbed in a collision while sometimes energy is given off.
However, my main point was not so much about the «make up» of ozone but more about the possibility that as long as oxygen atoms and molecules absorb enough energy from UV radiation to alter their structure it may be that they also produce an increase in their heat content, which should be greater at any points nearest to the source — i.e..
