The SETF office became a temporary lab on March 13th when Robert LeSuer, our President and resident Chemist, conducted his "Make a Solar Cell Workshop". With the assistance of his chemistry students from nearby Chicago State University, he demonstrated how to use berry juices, iodine, Titanium Oxide, glass slides and other materials to construct and to create a photovoltaic cell that generates electricity. The process is similar to the one used by solar cells. Different types of berry juices, such as strawberry, blueberry and mixtures were tested to see which one worked best for generating a current. Participants were fascinated by the process and enjoyed the "hands on" experience.
