The effectiveness of a mini photovoltaic cell by using light LED bulbs as a source of photon energy

Muxindo's LED bulb is one of the brands that are widely used by Indonesian people as
lighting in the home. This study aims to look at the effectiveness of the light spectrum of the 10,
15 and 20 Watt LED power bulbs as an energy source to generate electrical energy in
monocrystalline mini photovoltaic (PV) cell module. The light spectrum is compared with and
without the Fresnel lens before being transmitted to the PV surface. The test results show that the
PV output power is much better with a Fresnel lens (4.06> 1.67) mW. The efficiency of PV with
lens displays slightly different figures, 3.77% at 15 Watt bulb power, while without Fresnel lenses,
PV efficiency is 4.86% with a 20 Watt bulb. Need further research, for example, with Philips brand LED
bulbs
