Perovskite

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.

Scientists have created a solar cell of mutiple layers of different perovskite materials that has a claimed a peak efficiency of 26 percent. And can usefully convert light energy over much greater parts of the spectrum than standard silicon solar cells.

A new finding at the Lawrence Berkeley National Laboratory could reveal the full potential of perovskite solar cells, approaching their theoretical maximum efficiency of 31 percent.

To address the limitations or silicon-based solar cells, scientists at TU Wien in Vienna have combined perovskite-based solar cells that work at high temperatures with an electrochemical cell that allows the energy from ultraviolet light to be stored chemically.

Perovskite-based solar cells have been hampered by poor durability, but a new compound developed at the Swiss Federal Institute of Technology in Lausanne could lead to cells that are cheaper, highly efficient and more durable than current devices.

Researchers working at the Hong Kong Polytechnic University have created inexpensive, semi-transparent, high-efficiency perovskite solar cells with graphene electrodes.
