ANALISIS PERPUTARAN RADIASI SURYA TERHADAP KINERJA SEL FOTOLISTRIK SEBAGAI ENERGI RAMAH LINGKUNGAN DI NUSA PENIDA KABUPATEN KLUNGKUNG PROVINSI BALI

Photoelectric cells is an equipment made of semiconductor material of Silicone (Si14) functioned to catch and converse sun light to become electric energy directly. Through photoelectric phenomenon, that sun light as particles with frequency/wavelength of certain light can release electrons in a material. This electrons’ movement can produce electric current. The aim of this research was to find out the performance of a photoelectric cells collector in conversing sun light to become electric energy due to the rotation of solar radiation in Nusa Penida. The research was conducted at PLTS electric home solar system Nusa Penida for 5 days the measurement to the parameter of Current (Isc) and Voltage (Vsc). Each measurement had duration of lighting for 8 hours each from 09.00 until 16.00 Central Indonesian Time, with time interval of 30 minutes. Measurement and data analysis produced in the research on Saturday, June 29th 2013 obtained: the amount of solar radiation arrived at earth’s outer atmosphere was 1321.90 W/m2, and passed along to earth’s surface at 621.29 W/m2, and received by photoelectric cells collector as heat power at 113.63 Watt, and efficiency produced was 25.3%, and electric power produced was 28.74 Watt, and can be equalized with fossil energy of 0.0237 liter of gasoline, or equivalent to 106.65 rupiah. It meant that, photoelectric cells collector with area of 50 x 110cm2 in a day can protect earth from global warming of 28.74 Watt, in using of fossil energy at 0.0237 liter of gasoline. The efficient performance of photoelectric cells was still considered small. In order to achieve big capacity of electric power required a lot of collector modules and large area, so that with the growing of semiconductor technology, it is expected that whenever possible it can reduce electron binding energy on material, and optimize solar lighting system to photoelectric cells collector modules, so that the efficient performance of photoelectric cells can be expected to be above 90%. Key words: Photoelectric cells, Solar energy, Nusa Penida electric, Sun electric.
