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.

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.

2022 PV Module Reliability Scorecard results show resilience of the industry

This year a record number of manufacturers had one or more model types that were Top Performers in every reliability test – and six of these model types were also Top Performers in energy yield performance.

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.

Amazon invests in US-based solar cell production facility

Ambient Photonics will build a fully automated manufacturing facility to produce solar cells for powering consumer electronics.

Chinese PV Industry Brief: Longi to build 20 GW solar module plant

Longi has revealed plans to build a new panel factory in Anhui province, China Huaneng Group has announced a 1.3 GW renewables project in Heilongjiang province, and JinkoSolar has issued a warning about rising polysilicon prices.

‘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.

Novel way to turn semi-finished thin-film solar modules into colored BIPV panels

German scientists have developed a way to cut semi-fabricates into desired shapes and then apply a conductive oxide-metal-oxide electrode with the preferred color. They can structure the elements into modules via the backend interconnection process.
