How do scientists use the properties of waves when designing solar cells? (1 point)
They ensure that the nucleus of the metals in the solar cell are large, making the metal dense so that the photons in the light waves cannot pass through.
They ensure that the electrons on the surface of the cells are able to absorb the energy of photons in a high frequency wave.
They use low light waves so that electrons from the sun can pass their energy onto the photons easily.
They use light waves with a negative charge so that the electrons in the metal in the solar cells are repelled and move away.
