AI Customer ServiceVoltage versus distance is pretty self explanatory. The larger the distance between the light source and the solar cell, the smaller amount of energy that will be produced. This is because light spreads out as soon as it leaves the source, but the amount of light does not change.
When light of the right wavelength shines on the semiconductor material of a solar cell, the light creates a flow of electrons. This is known as the photoelectric effect. Small solar cells, like the one used in this project, can be used in circuits to charge batteries, power a calculator, or light an LED (light emitting diode).
Solar cells experience daily variations in light intensity, with the incident power from the sun varying between 0 and 1 kW/m 2. At low light levels, the effect of the shunt resistance becomes increasingly important.
Background: When light hits a solar cell the light is converted to “excited” electrons. The solar cell operates by collecting these electrons as electrical current and generating a voltage (i.e. electricity!). Here we will MEASURE the current as we change the brightness of the light (intensity). Current is measured in Amperes or “Amps”.
The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2. For example a system with 10 kW/m 2 incident on the solar cell would be operating at 10 suns, or at 10X.
Keep the distance and brightness of the light source constant, but vary the angle of the incoming light. Another variation would be to measure the power output of the solar cell as a function of the ambient temperature (see the Science Buddies project A Cool Way to Make Electricity: Solar Cell Power Output vs. Temperature.
