Solar Battery + Room Lamp

Again I have absolutely no idea on how this would work, but it would be nice if there were a lamp which also works as a solar panel.
My idea is a half-spherical shape with two holes like these:

Reduce the solar radiation before reaching the earth

OK. I don’t know anything about global warming, so if I’m being an idiot, just laugh it off.
Simply put, this solar powered glass plate floating on the orbit blocks some solar radiation. We can switch the plate from “transparent mode”, which just blocks only specific kind of light to “black mode”, which cut any kind of light off. We can switch the modes from the earth with the usual remote control. So it’s like putting sunglasses above the earth; sunglasses that can become usual glasses.

In short, you can ADJUST the sunlight coming to the earth.
Of course, only a single disc does not change anything, but if there are one thousand of them above your city, it can make a small change.

By the way, is it possible to transcend electricity in the air?
