Solar cells Coursework
Aim
I am trying to find out the relationship between light intensity and current produced by a solar cell and to explain how this happens.
Background Research
Solar cells need a sustainable amount of electricity to function properly. Solar cells transfer light energy into electrical energy. Although they involve no moving parts, they are high-tech solid-state devices. They are constructed by layered special materials called semi conducts; these are linked by electrical wires and arranged on a panel of glass (module). The panel will give out more energy depending light intensity it is getting. Light energy contains photons witch hit the solar panel and bump electrically charged particles around in the cell they then cause the electrons to move around and complete the circuit. This process repeats itself to give out energy.
Prediction
I think that when the light is moved further away than the solar cell the current will reduce because a solar cell needs light to create its current therefore without light it would not work. For example if it is moved four times, closer the solar cell will be 4 times more powerful. However if the Solar cell is moved four times further away then the current would of decreased and then stopped.
