Experimenting with Photoelectrochemical Cells in Drinking Straws: Practical Aids for Learning about Solar Energy in School or at Home
Appleyard, S. J.
Physics Education, v43 n3 p270-279 May 2008
Photoelectrochemical cells using dye-sensitized ZnO with a Cu[superscript 2+]/Fe[superscript 2+]/Fe[superscript 3+] electrolyte can be easily made at home or in a school classroom with household chemicals and other readily available materials. The cells, which are made with wire housed within plastic drinking straws, have open-circuit voltages of 0.5-0.7 V and short-circuit currents of about 0.5-2.5 mA cm[superscript -2]. Step-by-step instructions are provided on how to construct the photoelectrochemical cells, as are suggestions about how to use the cells to explore some concepts associated with utilizing solar energy. (Contains 5 figures and 1 table.)
