Given that there is a seemingly endless supply of energy available from the sun, solar, or photovoltaic (PV) cells, are becoming increasingly common. Photovoltaic cells, which are most often made out of silicon, a semiconductor, have the ability to convert light energy into electrical energy.
In this experiment, you will test a solar panel to determine how load (in this case, a resistor) affects its power output. You will create a potential-current curve, also known as an IV curve.
Use the Vernier Energy Sensor to determine current, voltage, and power.
Determine how power output varies depending on the resistance (load) in a circuit.
Determine the relationship between internal resistance and optimal resistance.
Create an IV curve for a solar panel.
