A few things need to be cleared up here for you. First, ozone concentrations increase in the stratosphere up to 25 km where it is a maximum. It decreases above to near the stratopause near 50 km. It is the combination of the presence of ozone and the lack of overturning or convection in the stratosphere which produce the increse in temperature throughout the stratosphere.

The absorption of ultra-violet radiation by the ozone layer which is present in the stratosphere is the reason for the increase of the temperature with height in the stratosphere.
The incident short-wave solar radiation is not directly absorbed by the atmosphere and it is the reflected solar radiation(long-wave radiation) from the earth's surface which heats the atmosphere from below.Hence the temperature decreases with height in the troposphere.But ,the ozone in the stratosphere directly absorbs the UV radiation fom the incident solar radiation and that is why there is an increase of temperature with height in the stratosphere.

Through the lower mesosphere and upper stratosphere, UV radiation interacts with oxygen to produce ozone. It also destroys the ozone. In the process, the gases absorb the UV radiation and warm up. The peak of this activity is at the stratopause, the boundary between the mesosphere and the stratosphere so the warmest place is on the stratopause. This means that the temperatures rise as you descend through the mesosphere and fall as you descend through the stratosphere.

The troposphere is warmed from the ground up so temperatures increase again from the tropopause as you descend through the troposphere.

the word indreases isn't a word first off lol

and its because temperature is created through something called "solar radiation" so when that radiation hits the earth it heats up the earth and the earth releases the heat, the radiation itself isn't hot its the act of absorbing it that makes it increase the earth surface in temperature. so as you get further from the surface the more air mass it has to heat and the more heat has already been put into the air below it leaving less for higher altitudes
