Random numbers are critical to encryption algorithms, but they're nigh-on impossible for computers to generate. Now, Swedish researchers say they've created a new, super-secure quantum random number generator using cheap perovskite LEDs.

Perovskite is quickly gaining on silicon in the solar cell field, but it has one major drawback – durability. Now, a new treatment has been shown to keep perovskite solar cells working at 99% of their efficiency after 1,000 hours of use.
-
The dynamic duo of silicon and perovskite continue their rampage through the solar cell industry. Researchers at KAUST have developed a new silicon/perovskite tandem solar cell with a record-breaking efficiency.
-
The humble X-ray may have received a long-overdue upgrade thanks to the development of a highly sensitive, printable X-ray detector that can operate over a wide range of energy levels, with potential in a wide range of real-world applications.
-
Perovskites are one of the most promising new materials for solar cell technology. Now engineers at the University of Rochester have developed a way to more than triple the material’s efficiency by adding a layer of reflective silver underneath it.
-
Greenhouse gases and plastic waste are two of the biggest environmental problems the world faces today. A new reactor from Cambridge tackles both at once, converting CO2 and used plastic bottles into useful materials, powered entirely by sunlight.
-
Perovskite and silicon are proving to be a formidable duo in the world of solar cells, and now they’ve hit a new record efficiency. A team at Helmholtz Zentrum Berlin (HZB) have developed solar cells with an efficiency of over 32%.
-
A new solar cell packs a record voltage and (arguably) a record efficiency for its kind. The tandem solar cell uses two layers of perovskite that tap into different wavelengths of light, plus a special surface treatment reduces wasted energy.
-
Gases used as refrigerants in cooling systems can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a solid-state material as a refrigerant.
-
Scientists have broken the efficiency record for tandem silicon-perovskite solar cells, surpassing the milestone of 30 percent for the first time. The new record takes the technology beyond the upper limits of silicon alone, using low-cost materials.
-
Before perovskite can become viable for solar cells, it needs to overcome a major durability issue. Engineers at Princeton have unveiled a new perovskite solar cell design that tests suggest could last as long as 30 years of real-world use.
-
Perovskites are promising solar cell candidates, but a major downside is that they degrade in direct sunlight. Researchers have now uncovered a root cause of the problem, and found a simple fix that can be applied during the manufacturing process.
