Tests on new designs for next-gen solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia’s Monash University, incorporating 3D-printed key components.
The machine can analyse 16 sample perovskite-based solar cells simultaneously, in parallel, dramatically speeding up the process.
The invention means that the performance and commercial potential of new compounds can be very rapidly evaluated, significantly speeding up the development process.

Semi-transparent solar cells that can be incorporated into window glass are a “game-changer” that could transform architecture, urban planning and electricity generation, Australian scientists say in a paper in Nano Energy.
The researchers – led by Professor Jacek Jasieniak from the ARC Centre of Excellence in Exciton Science (Exciton Science) and Monash University – have succeeded in producing next-gen perovskite solar cells that generate electricity while allowing light to pass through. They are now investigating how the new technology could be built into commercial products with Viridian Glass, Australia’s largest glass manufacturer.

A
literal “trick of the light” can detect imperfections in next-gen solar
cells, boosting their efficiency to match that of existing silicon-based
versions, researchers have found.
The discovery opens a
pathway to improved quality control for commercial production.
On small
scales, perovskite solar cells – which promise cheap and
abundant solar energy generation – are already almost as
efficient as silicon ones.
However, as
scale increases the perovskite cells perform less well, because of
nanoscale surface imperfections resulting from the way they are made.
As the number
of unwanted tiny lumps and bumps grows, the amount of solar
power generated per square centimetre drops off.
Now, however, Australian researchers have come up with a solution – using a camera.

Australian researchers unlock the key to cheaper high-tech telecom and medical diagnostic devices.
Scientists and engineers will soon have a much cheaper way of stabilising, blocking and steering light – potentially lowering the costs of high-tech equipment used in telecommunications, medical diagnostics and consumer electronics.
Researchers led by Dr Girish Lakhwani, a chief investigator for the Australian Research Council’s Centre of Excellence in Exciton Science (ACEx), have found a way to manipulate light produced by lasers at a fraction of the cost of existing methods.

This is one of the best science communication courses I have ever encountered. It teaches all research to think out of box and really simplify their research in lay man's language. I will highly recommend this to anyone looking to learn more about science communication.
