ABSTRACT

This research was aimed to utilize and make dry solar cells using electrolyte salt (NaCl) concentration variation with 5M, 7.5M, 10M and variations in electrode area 15cm2, 25cm2, 35cm2. Elektrodes used with thick copper plate that is 0,25 mm. This research used statistical description method to take the data. The datas which took among : light intensity by solarimeter, voltage output (V) and current output (I) of solar cell by multimeter, The result showed that the cleaning solar cells can produce a maximum voltage, solar cells with elektrodes extents 35cm2 using concentrated elektrolyte 10M. The other conclusion is by the light intensity of 1098 W/m2, it can interchangeable generate a voltage of 64 mV.

Keywords : solar cells, light intensity, salt water (NaCl), and copper plate.
