Converting electricity to light and some back to electricity back to power said light is preposterous nonsense we expect from people with no physics education or even common sense. These things amount to perpetual motion machines which don’t work. Every stage has losses, and fluorescent tubes are only about 20% efficient, the rest is produced as heat but its the best we have right now.

And as others have said, solar cells are never really transparent, and even when they absorb some photons and convert to electricity they also block other wavelengths and convert that to heat.

In general even using solar cells in the office is just plain lazy because the power outlet is literally available a few feet away. There are no cheap efficient solar cells available that warrant use of artificial light. If light is leaving through windows, then use reflective blinds. If light is entering the windows, turn the lighting down.

The light transmits all around the flourescent tube and IF the film is transparent or nearly so, it would have no effect on the amount of light reflected from the top of the light fixture.
