are preparing a project with your friend. You have found
some interesting material for the presentation and you want to read this text to your friend. You have 1.5 minutes to read the text silently, then be ready to read it out aloud. You will not have more than 1.5 minutes to read it.Solar panels are a commonly used form of technology which harness power from the
sun. They work by converting sunlight into electricity. However, most solar panels only
convert about 20% ot the incoming energy. This is because they can only capture certain
wavelengths of light.
Advances are being made in the field of solar panel technology. Recently a solar cell was
manufactured that can convert almost 45% of the rays’ energy. The panel consists of
different layers of material, and each layer can absorb a certain wavelength of light. The
panels also have lenses, which magnify the power of the sunlight. As the sunlight passes
through the layers, it strikes conductors, which create electrical fields. These electrical
fields produce a current of electricity.
