Why don't solar powered calculators work with low energy light bulbs?

They worked with standard filament bulbs.
john h don't you mean asinine?

Hi!

Solar Cells do not convert all light into electricity. They need light of specific frequencies to work.

Incandescent light has lots of light in the red end of the spectrum and this is what solar cells need.

Fluorescent lights, including the low-energy ones, produce most of their light at the blue end of the spectrum. Unfortunately solar cells are not very efficient at these wavelengths. That is why you can get it to work, but need to hold it almost under the light to get enough light on it.

If we could get solar cells to work at more frequencies, then their efficiency would improve enormously!

I hope this helps?
