Increasing the performance of solar cell by using red wavelength

In 2016, the United Nations Framework Convention on Climate Change established the Paris Agreement which discusses GHG emission mitigation, adaptation, and finance. Globally, Indonesia contributed 0.554 GT of CO2 which is equivalent to 1.49% of total GHG emissions. As a party of the Paris Agreement, Indonesian Government is committed to reduce the emissions by 29% by 2030. In order to participate in developing and building the renewable energy, several tests were carried out on solar panels that will support Solar Power Plants. Polycrystalline solar panels are panels with efficiencies ranging from 12% to 14%. The output power produced by solar panels is affected by the light radiation intensity and wavelength. However, previous studies have shown that in high sunlight level, the output power of solar panels actually decrease. Further research has been conducted in order to better understand the relationship between the wavelength of light and the output power produced by the solar panel. In order to increase the output power, sunlight was directed in such a way until certain wavelengths hit the panel. Based on the research result obtained, it showed that the red wavelength gave the best solar panel performance. Subsequently, this research has been successfully conducted to increase the efficiency of polycrystalline solar panels to reach values above 22%.
