The Solar Spark

The Solar Spark educational resources are produced by the SUPERGEN Excitonic Solar Cells Consortium. This is a group of research scientists from eight UK universities working together to do scientific research on Excitonic Solar Cells. Researchers work in the areas of polymer solar cells, dye-sensitised solar cells and tandem cells. They explore lots of relevant chemistry, physics and engineering behind the structure and design of these cells. The educational resources in this collection include practical activities that illustrate how solar photovoltaic cells work, future applications and the need for sustainable energy.

Chlorophyll fluorescence

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...

Marble Runs and Solar Cells

Produced by Solar Spark, this activity allows students to model the energy changes happening inside a photovoltaic cell. In a solar cell, electrons move to make an electrical current. The electrons act like the marbles in a marble run.

Marbles at the top of the run flow downhill through the run to the...

Anodising Titanium

By Solar Spark, this activity explores the relationship between light scattering and colour through anodising. This is the electrochemical process used to thicken the protective oxide layer found on several metals. Aluminium is the most common metal treated in this way, but others, including titanium can also be...

Colour Mixing

From Solar Spark, this simple demonstration shows the effect of adding colours. Photos and pictures are often made up from just four colours black, cyan, magenta and yellow. Different amounts of each colour combine to get all the colours of the rainbow and make the complete picture.

Solar cells are...
