Some of the electrons with energy due to heat enough to bond the shingles. Cause a stir. Electrons emitted cause the semiconductor Electrical power when they are plugged in to this substance.
Some electron with energy Heat enough to break the bond. The space in a Electrons ejected cause the semiconductor. Conductive when an electric field to connect with this material.
Some electron energy. Due to the heat, enough to let go of the bond, creating space. The electrons off causing the semiconductor. Conductivity when there is an electric field to connect to this substance.
