It works differently.

Ozone is a strong oxidant. Typically used in protein skimmer where people wants to increase the protein skimmer's performance by adding ozone to extract more protein waste (oil, fat, ammonia, nitrite and some nitrate...etc.) out of water. Too much ozone in the water can be lethal to tank inhabitants as well. That's why it is recommended to use redox/ORP monitor in conjunction with Ozone.

UV is more intended to "zap" microscopic animals in the water. As small animals are exposed to UV rays, UV alters the DNA of the outer shell, thereby killing or disabling the animals. Obviously, depending on dosage, UV works much more efficient for single celled animals such as algae (OK, maybe not just animals), ich parasites, and a number of other bacteria. For larger more complex animals (such as adult shrimps, fish...etc), it would require a much heavier dosage or longer exposure to make noticeable damages.

The key to UV usage is to make sure you lengthen the exposure time as long as possible, hence the "spiral" design of some UVS manufacturer.

so what does ozone + protein skimmer do in a planted tank?

Protein skimmer do not work in most FW tanks (planted tank included). Protein skimmer require hard water. Specialized pumps sends minute bubbles into the skimmer column. The surface tension of the bubbles attracts protein waste, and as the bubbles rise up to the surface, waste materials are carried along with the bubbles to the collection cup.

Bubbles require hard water to keep the surface tension up. Otherwise the bubble burst quickly. For tanks with soft water such as planted tanks, protein skimmer is useless.

Protein skimmer, on the other hand, could be used on some FW tanks such as african cichlid tanks or out door tanks for koi and goldfish, because the water is much harder (minerals rich) than planted tanks.

Technically, its the specific gravity of the water that allows protein skimmig, or 'foam fractionation' to work. Saltwater tanks have a higher gravity due to the alkalinity and salt.
Since ARLC tanks are very hard, and often contain some salts, you can get a protein skimmer to work, but at a limited capacity.
And really, protein skimming isn't necessary for a healthy FW tank, so there's no reason to really mess with it. SW tanks are much more sensitive, especially all the invertebrates (corals, shrimp, etc), so skimming improves water quality for those organisms.
