Comparative Analysis of the Performance of Monocrystalline, Polycrystalline, and Monocrystalline Solar Cells Coated with Graphene

Since the government promoted independent renewable power plants, especially solar energy generation, since then the development of solar energy power plants has increased very rapidly. The average annual growth rate of solar energy usage has reached 60% over the last few years. Photovoltaic (PV) solar cells are one of the most substantial technologies in renewable energy sources, which are simple and reliable for use in various purposes. Indonesia has an average global solar radiation energy potential of 4.5 to 5.5 KW/m2 /day. So that the use of solar energy with solar cell technology is an alternative to overcome the energy crisis. In the test that has been carried out for one week, several measurement results have been obtained. In the measurement of the intensity of solar radiation that has been carried out, the average solar radiation is 384.4 Watt/M2 /hour or 4612.8 Watt/M2 /Day, from the radiation measured, the average temperature is 29o Celsius and the average humidity is 79.8%. From the daily solar radiation potential that has been measured, the potential for generating electrical energy using solar panels reaches 234.4 watts/day for polycrystalline, 227.1 watts/day for monocrystalline, and 47.2 watts/day for graphene coating on monocrystalline. From the measured results, it is concluded that polycrystalline solar panels have the best production efficiency compared to other types.
