A nanomaterial made from phosphorus, known as phosphorene, is forming a key ingredient for more sustainable and efficient next-generation perovskite solar cells (PSCs).
                                              

PSCs which are one of the fastest developing new solar technologies and can achieve efficiencies comparable to more commonly used commercially available silicon solar cells.

For the first time, an international team of clean chemistry researchers led by Professor Joseph Shapter and Flinders University, has made very thin phosphorene nanosheets for low-temperature PSCs using the rapid shear of the University's revolutionary vortex fluidic device (VFD).

"Silicon is currently the standard for rooftop solar, and other solar panels, but they Take a lot of energy to produce them. They are not as sustainable as these newer options, "says assistant professor, now at University of Queensland.

" Phosphorene is an exciting material because it is a good conductor that will absorb visible light. In the past most non-metallic materials would have one property but not both, "he says.

" osphorus into phosphorene which can help produce more efficiently and also potentially 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, showing an extra efficiency of 2% -3% in electricity production." into making high quality 2-D phosphorene in large quantities along with other future materials such as graphene ̵

"The work with phosphorene is exploring the addition of different atoms to the matrix which is showing very promising results in catalysis, particularly in the area of ​​water splitting to produce hydrogen and oxygen," says Professor

With the ability to artificially produce perovskite structures, commercial viability is at the threshold and not too far away once the cells can be successfully scaled up. Meanwhile research around the world continues to look for ways to improve and optimize perovskite cell performance.
