Outdoor Solar Lights

Are photovoltaic and solar cells the same? And same question… do they all run on indoor artificial light like calculators’ and watches’ do?

probably a little bit, but very poorly.

eg, if you had a 100w bulb, 5 feet away from a 1×1 sq ft panel, at 10% efficiency (it would really be far less), you’d get

100*0.1*1/(4*pi*5^2) =0.03 watts

that is, 100 watts in to produce 3/100 of one watt.
worse, that assumes 10% efficiency, which is likely higher than you’d really achieve.
