Hey! Looks like you have stumbled on the section of our website where we have archived articles from our old business model.
In 2019 the original founding team returned to run Next Investors, we changed our business model to only write about stocks we carefully research and are invested in for the long term.
The below articles were written under our previous business model. We have kept these articles online here for your reference.
Our new mission is to build a high performing ASX micro cap investment portfolio and share our research, analysis and investment strategy with our readers.

A new nanomaterial made from phosphorus, known as phosphorene, is shaping up as 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 stress 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 adjunct Professor Shapter, 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.
“We’ve found an exciting new way to convert exfoliated black phosphorus into phosphorene which can help produce more efficient 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.”
Research into making high quality 2D phosphorene in large quantities – along with other future materials such as graphene – are paving the way to more efficient and sustainable production with the use of the SA-made VFD, near-infrared laser light pulses, and even an industrial-scale microwave oven.
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.
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 optimise perovskite cell performance.
Professor of Clean Technology Colin Raston, Dr Kasturi Vimalanathan and Dr Gibson are among a team of Flinders Institute for Nanoscale Science and Technology researchers looking to improve solar cell efficiency with new and improved solar cell materials and processing systems.
Professor Shaper also is continuing the pioneering solar-cell research at the UQ with Dr Munkhbayar Batmunkh and Abdulaziz Bati, all co-authors of the new paper ‘Efficient Production of Phosphorene Nanosheets via Shear Stress Mediated Exfoliation for Low-Temperature Perovskite Solar Cells.
The new paper by M Batmunkh, K Vimalanathan, C Wu, ASR Bati, L Yu, SA Tawfik, MJ Ford, TJ Macdonald, CL Raston, S Priya, CT Gibson and JG Shapter (University of Queensland, Pennsylvania State University, Virginia Tech, UTS, RMIT, UCL and Flinders University) has been published in Small Methods (Wiley) DOI: 10.1002/smtd.201800521.
The latest study was supported by an Australian Research Council Discovery Program, Royal Society of Chemistry research grants, Microscopy Australia, Australian National Fabrication Facility and the new Flinders Microscopy and Microanalysis Centre.
