How A Solar Cell Works
A solar cell works by absorbing in light from anything that produces light, the sun for example, and makes it into energy and that energy gets released into an object that needs energy, a light bulb for example. It does this by its quantum dots absorbing the energy and releasing it. Quantum dots are Silicones (the substance that a solar cell is made out of) that got cut off by its main source multiple times. When the quantum dots absorb the energy form the light, they also absorb short wavelengths of light. When the quantum dots do absorb the wavelengths, they get larger in different areas of the solar spectrum and this makes it useful for solar energy conversion. But in order for the light to be absorbed by a solar cell, the light must be greater than the energy. The solar cell must absorb at a wavelength slightly greater than one-thousand one hundred nanometers. If a solar cell made of quantum dots is placed on a normal silicon cell, the absorption starts to enhance and the silicon cell absorption starts to ware off. This is called a tandem solar cell because the two cells work in a series. This also improves the amount of light and energy that a this kind of cell can hold and produce energy by 30% or 35%.
