Get the juice out of the sun
Make your very own solar cells from berry juice and dark-green leaves! The coloring agents contained within (anthocyanin and chlorophyll, respectively) are used for the fabrication of functional cells. The coloring agents belong to a class of materials called organic semiconductors. Charge carriers are generated upon irradiation of the materials in solar cells. Therefore, an electrical current can be generated from light and easy-to-make solar cells can be realized.
