Solar cell in a drinking straw

In this experiment you will be making a solar cell in a drinking straw. You will be using the good light-absorbing properties of raspberry juice to capture electricity from sunlight, using some nice straightforward chemistry.

The solar cell in a drinking straw is a great way of allowing students to make their own solar cells out of cheap and readily accessible materials in their own school lab. The mechanism behind the solar cell is similar to that used in a Dye-Sensitised Solar Cell (DSSC) but uses different electrolyte and electrode materials to demonstrate the concept. 

 A 45-60 minute activity.
