Science doesn’t usually adopt tactics from the world of retail business. But a family of cleverly designed organic molecules has just begun offering a two-for-one deal in energy conversion. Researchers uncovered the chemistry “special”—a doubling of the energy that can be extracted from a single photon of light—while studying the way a molecule’s electronic properties can be customized by tailoring its structure. Their finding may lead to low-cost materials for solar cells that convert sunlight . . .
