the sulphatoxide of copper, S.O4. Cu., is decomposed, pure copper is deposited on the copper electrode, while the sul-phatoxygen (S.O4.) traverses the porous cup, and unites with the zinc ...

The anode (positive electrode) is made from impure copper and the cathode (negative electrode) is made from pure copper. Pure copper forms on the cathode. The slideshow shows how this works.

Under standard illumination conditions, the cell achieved a power conversion efficiency of 20.10%, an open-circuit voltage of 1.084 V, and a fill factor of 78.77%, which the research team ...
