STUDI PERUBAHAN ENERGI MATAHARI MENJADI ENERGI LISTRIK DENGAN MENGGUNAKAN SEL SILIKON DIODA SILINDER

Abstract

The study of solar energy conversion to electrical energy by using silicon diode in cylindrical cells has been experimentally investigated. Silicon cells is connected to series and parallel for each 25 and 50 diode with glass and no glass plate respectively. The measurement is conducted by voltage and ampere meter to show the change of voltage and current. The intensity of sun light and heat uses Lux meter and thermometer in 10 minutes interval from 10.00 Wibb until 13.00 Wibb for 6 days. The results show that the lowest average intensity is 35.56 K lux (at 10.00 Wibb) and the biggest average intensity is 108.30 K lux (at 13.00 Wibb). For 25 diodes the results are as follows. The minimum current (series, with glass plate) is 21.33 μA at 11.50 Wibb. The maximum current (parallel, with no glass) is 1027 μA at 12.50 Wibb.The minimum voltage (parallel, with glass plate) is 223 mV at 11.00 Wibb. The maximum voltage (series, with no glass) is 7.033 V at 12.50 Wibb. For 50 diodes the results are as follows. The minimum current ( series, with glass plate ) is 21.33 μA at 11.50 Wibb. The maximum current (parallel, with no glass) is 2037 μA at 12.50 Wibb. The minimum voltage (parallel, with glass plate) is 232.30 mV at 11.00 Wibb. The maximum voltage (series, with no glass) is 12.50 V at 12.50 Wibb.
