Nitrogen-doped carbon nanodots for more stable, efficient perovskite solar cells

A Spanish-Italian research group was able to improve the efficiency and stability of a standard perovskite solar cell by adding nitrogen-doped carbon dots as an additive. The carbon dots were then blended with the perovskite precursor solution at two different concentration levels and both were deposited by spin coating on the perovskite layer.

UK startup develops Brayton pumped thermal tech for renewables storage

UK-based Synchrostor has developed a new pumped thermal energy storage (PTES) system. It is purportedly fully reversible in 30 milliseconds and can achieve a round-trip efficiency of around 70%. The proposed storage technology can also provide grid inertia and ancillary services.

About one-third of disused PV panels fit for reuse, says Australian consortium

Reclaim PV Recycling and the Circular PV Alliance (CPVA) have have agreed to jointly develop standards and testing procedures to support the reuse and resale of solar panels in Australia. Reclaim PV recently discovered that more than 31% of the solar panels collected in the Australian state of Queensland could be considered for reuse, rather than recycling.

Solar that works in the shade

Conditions that are 10% shaded can render a typical solar panel useless, but Optivolt said its technology can deliver up to 25 times more power in the shade than conventional panels.

Cost comparison between lithium batteries, fuel cells, reversible solid oxide cells as storage for off-grid rooftop PV

Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modeling assumed a typical commercial building in Los Angeles.

Vertical optical-fiber solar cell hybrid system from South Korea

South Korean scientists have built a vertical three-dimensional fiber-optic solar-cell system with greater maximum efficiency than planar solar modules, as well as a lower surface requirement.

Australian researchers crack ‘nighttime’ solar

Researchers from the University of New South Wales have made a major breakthrough in what was previously conceived of only in theoretical terms – namely, “nighttime” solar power.

‘Pulsed Joule heating’ tech to remove snow, frost, ice from solar modules

US scientists have developed a way to remove snow and ice from solar panels at a much faster rate than conventional approaches. It is based on a glass coating on a film with high optical transparency and superhydrophobicity.
