What materials are used on solar panels to allow them to produce electricity?

Rays of sunlight hit the solar panel and are
absorbed by semi-conducting materials such as silicon.
 Photovoltaic cells are
usually made from silicon, an excess material that constitutes more
than 28 percent of the Earth's crust.
These cells are created by bonding two
wafers of silicon that are connected to metal wires
The top water is silicon is thin and bottom is thicker the wafers produce electricity as absorb solar radiation

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

You will hear a hissing sound because of the carbon dioxide escaping the can or bottle
