GCSE PHYSICS COURSEWORK: SOLAR CELL INVESTIGATION ==> PLANNING AIM I am trying to find out how the current changes with the area of the solar cells. THEORY The energy in light can be transformed into electricity when shone onto semiconductor materials. Silicon and germanium normally have electrons in low energy states. Absorption of light excites these electrons into higher states and generates a voltage (typically 0.5 V per cell). As more light is absorbed, more electrons are excited and the current supplied increases. The energy of the photons transfer to electrons in the semiconductor. The energized electrons then break free for the silicon atoms and transfer them to an electric circuit If we completely cover the top of a solar panel then, then photons cannot get through the conductor, and the current is lost. Internal Resistance (called series resistance) if this is high then this means high losses, to minimize the losses; the cell is covered...
