Yes light-bulbs work, sort of, but you have to illuminate every cell. The output is regulated by the cell with the weakest illumination.
Additionally the sun is very strong, 1000W of light or more per square meter. A light-bulb is weaker, so less output. A 100W bulb may have only 5W of light, and it doesn't cover the panel, so you can expect something like 1% of the sun's output. The spectrum of a light-bulb is actually more appropriate for a silicon solar panel, as the silicon panel responds best to red colours.

Yes, but why?
If you've got the light-bulb, you've already got more
electricity than you will get out of the solar panel.

Yes. Most solar powered calculators work like this.

Solar radiation mostly visible light and infra red waves.Bulb also(incandicent bulb not cfls) produce mostly heat and light.So they must work but it not efficient method!

how can i calculate the output watts of the bulb if it was 1000w or any other
