A simplified fabrication process for high efficiency solar cells

A team of EPFL and CSEM researchers in Neuch√Ętel presents in Nature Energy a new astonishing method of creating crystalline solar cells with electrical contacts at the rear, suppressing all shadowing at the front. Thanks ...

Researchers capture excess photon energy to produce solar fuels

Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have developed a proof-of-principle photoelectrochemical cell capable of capturing excess photon energy normally lost to generating ...

Surge in coal pollution led to smaller newborns: study

In fresh evidence about the dangers of coal pollution, a scientist on Monday said a switch to coal-fired power in a southern US state after a nuclear accident in 1979 led to a sharp fall in birthweight, a benchmark of health.

Converting water into hydrogen more efficiently

Scientists have long been puzzled why it is easier to produce hydrogen from water in an acidic environment than in an alkaline environment. Marc Koper comes with an explanation: the reason is the electric field at the surface ...

Researchers show that enzyme function inhibits battery ageing

It has been known in biology for a long time that the excited oxygen molecule singlet oxygen is the main cause of ageing in cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide ...

Uranium from seawater factors into nuclear power

Trace amounts of uranium exist in seawater, but efforts to extract that critical ingredient for nuclear power have produced insufficient quantities to make it a viable source for those countries that lack uranium mines. A ...

Research pinpoints promise of polycrystalline perovskites

A team of scientists from the Energy Department's National Renewable Energy Laboratory (NREL) determined that surface recombination limits the performance of polycrystalline perovskite solar cells.
