Abstract

Copper-zinc pair (Cu−Zn) is a pair of electrodes that are often used in sea water Voltaic cells as a source of renewable electrical energy. however, the Cu cathode experiences corrosion when reacting with seawater. Therefore, this study was conducted by electroplating Ag on Cu, but due to the low intensity of the light produced, this study used joule thief to increase the amount of energy present in the volume of the voltaic cell. In voltaic cell system composed of 20 cells with sea water electrolytes and Cu(Ag)−Zn electrode pairs. Inter-cell electrodes are connected in series with connecting cables and sea water is replaced every 24 hours. In this system the measurement of electrode mass and electrical characteristics (voltage, current and light intensity) for 72 hours using joule thief and without using joule thief. The results showed that voltaic cells that use joule thief circuits produce light intensity 3 times greater than without the use of joule thief circuits.
