Light heats a photocell, and the difference in temperature creates an electric current(:
Yes
light of a cell
I might be wrong on this one, but I believe it is either a cell or a photocell. A cell would be correct, a photocell converts light energy into electrical energy.
photocell
Photocells are designed to work at night when it gets dark and turn off in the morning when it gets lighter. If the photocell is on during the day then it is not working the way it was designed to. Time to get a new one.
A: Photocell and LED cannot work directly because these are different devices. But yes each independently can work as a unit all you need is some buffering.
it creates a dc current
By covering the photo cell and if the relay coil doesnt work.

There is a lot of things when you talked about photocell... well in electronics world of terms the main functions of photocell are for sensing which provides limits or safety.Read more: http://wiki.answers.com/What_is_the_function_of_a_photocell#ixzz1lZGBI2wU
A: A photocell is like a variable resistor it will change resistance with light the ratio of dark:light resistance decides the output. So yes it should work with 9volts

It will if it can not 'see' the light.- ie, if there is a shade or something between it and the light.
During the day they had to work as slave labourers.

You can buy 6v photocell dusk to dawn switches from Acetek photocells
