Even though solar energy is a very
useful source of energy right now, the technology improves almost
every day. Just now a new material for solar panels, called
Perovskite, has been discovered. This new material is five times
cheaper than the current material and has one special feature. It can
not only absorb light to convert it into electricity, it can also
emit light. In addition to that it can be produced in different
colors. That means that in its semi-translucent form, it could
replace current windows. These new windows could produce electricity
in sunlight and serve as light decorations or as space for adverts
during night. Due to the multitude of colors this material can take,
even flat screen displays could be made out of it. That way smart
phones, tablets or any kind of electrical device with a flat screen
could be recharged by lying in the sun. Clearly, Perovskite is a huge
advance in terms of energy safety in the future.
