Perovskite

Mercedes-Benz has unveiled a list of research programs and future technologies it's working on – including a "new kind of solar paint" it says could generate enough energy for up to 20,000 km (12,427 miles) of driving per year under ideal conditions.

From a New York rooftop in the 1800s to their first journey to space. From kidnappings and bribery to a world-changing mistake with an inkwell... Solar panels are one of humanity's greatest inventions, and their history is more fun than you thought.

Perovskite materials are poised to take on the reigning champion of solar, silicon, but their stability is holding them back. Now, scientists in China have developed a new type of hybrid perovskite that boasts a very good efficiency over a long life.

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.
