Solar Cell EA

The mono-crystaline solar panel has a maximum rating of 4.4V, 90mA. It can be easily energised by a bright lamp or sunlight.

Sudents can explore the behaviour of the solar cell:

• Investigate how the output voltage varies with the area of cell exposed to the light

• Use filters to investigate how the output voltage varies with colour/wavelength of light

• Use a light meter and investigate how the output voltage varies with light intensity

• Determine the optimum electrical load for maximum power transfer for a known light intensity

• Determine how the maximum power varies with the light intensity when the electrical load is fixed
