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
hope it helps

Divide 108.2 x 10^6 into 1.5 x 10 and the result will be in au (astronomical units)

Sorry i don’t know what to do
