Solar Cell

Authors Avatar

Experiment to investigate how the output voltage from a solar panel varies as the light intensity varies.

Solar cells transferred light energy into electrical energy.

Apparatus :-

Lamp

Ruler

Multi-meter

Solar panel

Red and black wires

As part as my investigation, I am going to measure the output voltage form the solar panel. The range we need to use is 200mV, to see if the mill volts output varies with the distance. MV stands for mill-volts; a mill-volt is 1/1000 of a volt.

At first you place the meter ruler and follow on by placing the lamp at the end of the ruler where is shows ‘0’. To connect both black and red leads from the solar cell to the multi-meter. You the place the solar cell on top of the ruler at 100mm and record the reading in mV. You carry on the experiment by doing the same every 100mm, e.g. 200mm, 300mm etc. this will continue until I reach 1000mm as the ruler is a ...
