Source sentences:
text: These π electrons can be excited by light in or near the visible part of the spectrum from the molecule's highest occupied molecular orbital (HOMO) to the lowest unoccupied molecular orbital (LUMO), denoted by a π -π
text: Monocrystalline solar panels have the highest efficiency rates since they are made out of the highest-grade silicon and their single-cell structure creates minimal resistance to the flow of electricity once the electrons are excited by the sun.
