I don’t see how copper wire would have any effect at all.
There is no such thing as a maintenance free garden
Algae will grow on outdoor surfaces if the light, temperature and moisture conditions suit it. You will need to clean your porcelain patio just like you need to clean your porcelain bathroom tiles if you want to keep them looking fresh, even more so because your garden is a less controlled environment where the weather will bring in plenty of organic matter to feed slimes and algae’s and lichens etc and while the porcelain might be hard and impervious to water, the grout isn’t, and grout can crack over time especially after freeze thaw cycles that happen outdoors every winter, and in summer the temperatures can spike and crash on a daily basis, especially if the tiles are dark in color
