Analysis of Coil Effect and Number of Turns for Power Generation in Compact Disc Solar Cell

A compact disc can be made to function like a solar cell because a piece of a compact disc that is wired can generate electricity. This process occurs due to the photoelectric or photovoltaic effect. When sunlight strikes an object that is sensitive to light, that object can generate voltage. There are several factors that influence the generated voltage, namely the number of turns, the Zener diode, and the intensity of light received. This research is conducted to analyze the impact of the number of turns on a compact disc. This study is an implementational research where it will create, modify, and analyze the impact of light intensity on the compact disc, thus this research will use experimental methods. The data was obtained by creating and measuring a device. The results indicate that the compact disc experiences an increase in voltage generated with the addition of the number of turns and the Zener diode used; furthermore, light intensity also plays an important role in the voltage produced. The best compact disc is type 1, type 3 at the peak point with a sunlight intensity of 94,400 Lux, producing a voltage of 2.4 volts. This type features an axial winding with 60 turns and 5 Zener diodes. A simple solar power system was created using this type 1, type 3, generating a power output of 1.3 W for series connection and 0.7 W for parallel connection, with an efficiency of 5.7
