A phosphorus-derived nanomaterial known as phosphorus is becoming a key component for more sustainable and efficient next-generation perovskite solar cells.

PSCs, which are one of the fastest growing new solar technologies and can achieve efficiencies comparable to the commonly available silicon solar cells. Flinders University has very thin phosphorus nanosheets for low-temperature PSCs using the high shear stress of the revolutionary vortex fluid device (VFD) produced by the University.

"Silicon is currently the standard for solar panels on the roof and other solar panels They are not as sustainable as these newer options," says Professor Shapter of the University of Queensland.

"Phosphorous is an exciting material because it is a good conductor that absorbs visibly. In the past, most non-metallic materials had one property, but not both," he says.

"We have found an exciting new way to transform exfoliated black phosphorus into phosphorus, which can produce more efficient and possibly cheaper solar cells," says Dr. Christopher Gibson from the College of Science and Engineering at Flinders University.

"Our latest experiments have improved the potential of phosphene in solar cells. This shows an additional efficiency of 2 to 3% in power generation."

Research on the production of high-quality 2-D phosphorus in large quantities ̵

1; along with others future materials such as graphene – pave the way for more efficiency and sustainability Manufacturing with SA-made VFD, near-infrared laser light pulses and even a microwave oven on an industrial scale.

"Working with phosphorus investigates the addition of various atoms to the matrix, which is very promising, leading to catalysis, especially in the area of ​​water splitting to produce hydrogen and oxygen," says Professor Shapter.

With the ability to artificially create perovskite structures, commercia viability is at the threshold and not too far away as soon as the cells can be successfully enlarged. In the meantime, efforts are being made worldwide to improve and optimize the performance of perovskite cells.
