NREL hits new efficiency record for quantum dot cell

Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have created a solar cell using colloidal quantum dots, which achieved 13.4% conversion efficiency – a new world record for this emerging technology.

Yale researchers use Fossilized Diatoms to make organic PV more cost-efficient

Fossilized Diatoms, an algae that has the ability to manipulate light, are being used to solve a design problem that has long plagued the proliferation of organic solar cells. The diatoms can be found in all waters and in the bark of trees. They possess a skeleton made of nanostructured silica or glass.

Berkeley scientists boost battery capacities

Scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have made progress with cathodes made from ‘disordered’ materials, a technology which could greatly increase the storage capacity of lithium batteries.
