Our booth, supported by the NSF Center for Chemical Innovation in Solar Fuels, is all about solar energy and renewable fuels. We will have physical demos of solar powered fuel cells and silicon solar panels that attendees can interact with and ask questions of scientists doing research on the topics. Most importantly though, our booth will be a station where kids (and adults!) can make their own dye-sensitized solar cells using blackberry juice and other common household materials. Up to 5 people can be making a cell at once and it only takes 5 min to complete. Last year, hundreds of cells were made by attendees and our booth was busy from the very beginning until the end of the Expo. The booth will be staffed by scientists from Caltech currently doing research on solar energy and water-splitting to make renewable fuel sources. These scientists are trained on how to communicate with the public and kids of all ages to make the topic accessible and fun.
