Solar Cell Could Dramatically Improve Energy Harvest

A special coating could dramatically improve the percentage of energy that can be harvested from solar cells by splitting photons in two, new research suggests.

For every photon (or particle of light) that hits a solar cell, the coating — called pentacene — doubles the number of electrons, and energy, that can be harvested, at least with high-energy blue or green wavelengths of light.
