An international team has succeeded in considerably increasing the efficiency for direct solar water splitting with a tandem solar cell whose surfaces have been selectively modified. The new record value is 14 percent and thus tops the previous record of 12.4 percent, broken now for the first time in 17 years.

Scientists have invented a new way to view and create what they are calling 'an electron superhighway' in an organic semiconductor. This approach promises to allow electrons to flow faster and farther - aiding the hunt for flexible electronics, organic solar cells, and other low-cost alternatives to silicon.

Read moreTelecommunication networks will soon have to exploit the quantum properties of light. Researchers recently generated directly cross-polarized photon pairs on a chip, a first in quantum optics. Polarization will now be among the controllable parameters for harnessing light, helping the creation of low cost, high performance, energy efficient technologies.
