Technology and R&D

The comparison of two solar cladded roofs in Sydney, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.

Carbon never goes away, says Associate Professor Tianyi Ma, but if industrial carbon-dioxide emissions can be cleanly, renewable catalysed into chemicals and fuels that we need, we can reduce the overall GHG burden on the earth’s atmosphere.

Developed by the Korea Institute of Energy Research (KIER), the “non-destructive” technology is claimed to enable the recovery of 100% of a module’s glass and to allow the reuse of silicon for producing new solar cells with an efficiency of 20.05%.

The Australian Energy Market Operator will later this month commence testing of a cloud-based simulator designed to accelerate the grid connection process for developers of energy projects including large-scale wind and solar.

Halide perovskites combined with conventional silicon could help solar break the 26% efficiency barrier – disrupting the technology without disrupting business systems.

Next Energy and Marubeni are developing a blockchain tech for PV module inspection – with the support of the Japanese government – which they claim is able to provide data on a panel’s traceability and components as well as verifying that the data were not modified or tampered with.

Researchers at The Australian National University claim to have set a world record for bifacial solar PV cell efficiency that they say could boost the energy output of solar farms by 30%.

The new headquarters planned by DEWA is intended to consume no more annual electricity than it generates, from a large volume of rooftop and building-integrated PV.

Researchers at Monash University have published a new study in which high voltage lithium batteries, such as those used in electric vehicles and grid scale energy storage systems, are tested with a novel lithium salt shown to be far less hazardous than current conventional materials.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.
