My understanding is that ozone constantly decomposes to O2, the rate varies tremendously depending on temperature and other conditions. Ambient sunlight at the 'ozone layer' constantly generates ozone which constantly decomposes to 02. CFC's act as a catalyst for the O3 to O2 conversion which reduces the ozone half life which causes an ozone 'hole'.
Sunlight has shortwave UV that splits O2 into two oxygen atoms. These combine with O2 to make O3, ozone. Longer UV wavelengths split O3 into O2 and O, almost all of which recombine to make O3, ozone. No sunlight, O3 is stable in the stratosphere.
