The effect of visible wavelengths on performance of solar cell

Abstract

The solar cell is sometimes called "optical cell" or "photovoltaic cell" It is a device based on absorbing the fallen photons from sunlight and transforming them into a continuous electrical current (DC) through the properties of those substances that are by converting sunlight (sunlight) into electricity using elements that have the capacity to do so, such as silicon, which is extracted from the sand. The pure which causes the sun to fall (light) has to trigger a movement in the electrons whose movement leads to the generation of electric current. In this study the experimental Curriculum (laboratory experiments) was used to see how solar cells are affected by optical filters and when any of them are there higher intensity of the future various filters (Red – Yellow – Green – Blue) with a fixed-intensity light bulb and a solar cell have been used to demonstrate which of these filters are with this is the highest intensity of the future and through the results and readings it is true that the highest efficiency was with the red wavelength and is equal to 0.0127 and the efficiency of the yellow wavelength 0.0113 and efficiency of the green wavelength 0.0103 and the efficiency of the blue wavelength 0.0101 is illustrated by the results that efficiency increases with increasing the wavelength But the yellow wavelength is the highest efficient because its high absorption, as well as the attenuation of light current is almost non – existent , but the experiment began with red and the heat of the solar cell rose and this led to a lower yellow color efficiency than red.
