Perovskite

Windows capable of harvesting energy from the sun have been on the horizon for a number of years, but they're yet to help cut down a building's energy costs. A new development from Australian researchers may change that.

Solar cells are constantly improving on the road to maximum efficiency. Now, three records have been broken by two different devices, including one that pushes the highest overall solar conversion efficiency towards the 50-percent mark.

The Sun is a great source of energy, but of course those rays can be damaging as well. Engineers in Korea have now developed a new way to make perovskite solar cells to protect them from the elements without reducing their efficiency.

Stacking perovskite solar cells on top of silicon ones is one way to increase the amount of sunlight harnessed. Now researchers at Australian National University (ANU) have broken a new efficiency record for these tandem solar cells.

Engineers at MIT are developing a way to turn the humble RFID tag into a light-powered sensor for the internet of things.

Silicon is fast approaching its theoretical limit for solar efficiency, but pairing it up with other materials could help break through. Researchers have developed a new technique for combining silicon and perovskite solar cells, and reported a new record efficiency of 25.2 percent.

Over the last few years, perovskite has proven itself to be a promising material for photovoltaic solar cells, but it’s not without its problems. Now, a team has found a way to helps solve at least one of those issues, removing toxic lead from the device by substituting in titanium.

​A team of scientists from Stanford University has discovered a method of constructing perovskite solar cells with enhanced durability by taking inspiration from the honeycomb structure of insect eyes.

A new manufacturing breakthrough allows for lower cost and higher efficiency perovskite solar cells to move forward. Researchers at the University of Toronto have developed a new chemical reaction that solves one of the key challenges holding back development of the relatively new class of cells.

Energy harvesting devices that generate electricity from light, heat, and mechanical pressure in a single package may soon be possible. Researchers from the University of Oulu have discovered a crystal mineral material that is able to simultaneously generate electricity from all these sources.

Perovskite solar cells hold major potential for the future of renewable energy thanks to being cheap, easy to produce and are so flexible that they can even be sprayed or painted on surfaces. Now researchers have set the efficiency record for the biggest perovskite solar cells so far.

Perovskite solar cell technology has made great strides over the past few years. Now researchers have developed a new manufacturing technique that could increase the output of a perovskite solar cell by up to 25 percent.
