New path to solar energy via solid-state photovoltaics

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new route to energy production overcomes the bandgap voltage limitation that continues to plague conventional solid-state solar cells.

Why atoms in solid matter show a preference for certain arrangements

Nature likes some symmetries, but dislikes others. Ordered solids often display a so-called 6-fold rotation symmetry. To achieve this kind of symmetry, the atoms in a plane surround themselves with six neighbours in an arrangement similar to that found in a honeycomb. As opposed to this, ordered materials with 7-fold, 9-fold or 11-fold symmetries do not appear to arise in nature.

Model predicts and describes how materials break

For the first time ever, a study of this new mathematical model has managed to describe the fracture process for materials such as glass, polymers, concrete, ceramics, metals, rocks, and even certain geological fractures.
