Colorless Windows That Transform Sunlight Into Electricity

Abstract

Solar cells help us use less coal or oil when we make electricity. This way, we cause fewer problems for the environment. Most solar panels are expensive, and they cannot be used for windows because they are not transparent, so they hide your view. But solar windows can be created with special chemicals called organic colorants. These windows can catch sunlight and use its energy to make electricity, but you can still see a beautiful view through them. The windows we made are inexpensive and keep the colors of your view unchanged. Each colorless window makes 100 watts of electricity, which is enough to recharge 20 smartphones at the same time. Because we can use these cheap, colorless, solar windows everywhere, we could make a lot of clean energy!
