I am doing some coursework on photovoltaic cells. But i need to know where electricity goes after it has been genereated by the photovoltaic cell.
A couple of other things; Is the electricty sent thorugh an amplifier so that the voltage can be increased? What sort of voltages are produced from average sunlight by the PV cell? Since I will be using a light bulb to replicate the Sun, what sort of distance shall i have the bulb/what power bulb shall I use?
Thanks a lot.

Just came home from the beach and my skin is killing me! I need something quick and easy for this sunburn to calm down.
As the Sun radiate power in a radiation form,its mass peters out. So light ray has no mass contents?

Who has proven that light does not contain mass.Where does it say any where in Physics that the light particle is a particle with volume but no density?
