Defects, which inevitably arise when manufacturing so-called CIGS cells, can reduce their power output, but the effect is much less common and much more localised than expected.

Improved nanosecond imaging technology could help us see ultrasmall and ultrafast processes like never before.

Researchers developed a new 'one-pot' method to make nanosheets using less rare metals. Their discovery should allow for the energy-making process to be more eco-friendly.

Researchers have fabricated a gallium nitride (GaN) transistor using diamond, which of all natural materials has the highest thermal conductivity on earth, as a substrate, and they succeeded in increasing heat dissipation by more than two times compared with conventional transistors.

Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours.

Findings could play role in shaping sustainable habitation on the red planet - and clean energy production back home.
