Purpose of This Note
When performing experiments with dye solar cells, light is focused on the cell and its current
response is measured. The generated current depends strongly on the intensity of the light.
In order to calculate the efficiency of a solar cell, the optical power of the incident light has to
be known. This technical note explains how to measure and calculate the optical power of
your light source.
