Tiny 'LEGO brick' -style studs make solar panels a quarter more efficient

Posted: 18 Oct 2013 05:44 AM PDT

Most solar cells are made using thick layers of material to absorb sunlight, but have been limited in the past by relatively high costs. Many new, lower cost designs are limited as their layer of light-absorbing material is too thin to extract enough energy. In new research, scientists have demonstrated that the efficiency of all solar panel designs could be improved by up to 22 per cent by covering their surface with aluminium studs that bend and trap light inside the absorbing layer.

A hologram-like display of a patient's organs based on molecular PET/CT images helps surgeons plan surgery by allowing them to see detailed anatomical structure, peel away layers of tissue, and see all sides of a tumor, before entering the operating room to excise it.

Watching the heartbeat of molecules
