2060 net-zero vow nudges other nations to accelerate climate efforts, experts say
China s pledge to be carbon neutral by 2060 sets an example for other countries, and its energy policies will play a central role in achieving that goal, said energy experts. The carbon neutral pledge has really done a lot to inject new momentum into the global climate negotiations, said Barbara Finemore, founder of the China Program of Natural Resources Defense Council, a New York-based environmental advocacy group.
Australian researchers target rooftop solar in hunt for grid security
The University of New South Wales is leading a new research project to determine how rooftop solar PV and other distributed energy resources, including small-scale batteries, can be integrated into Australia s power grid.From pv magazine Australia The University of New South Wales (UNSW) has launched a AUD 2.1 million ($1.6 million) research project to assess how rooftop solar PV and other small-scale distributed energy resources (DER) respond to unexpected failures in the National Electricity Market (NEM), and how such assets can be used to bolster power system security. The three-year project .
Monograin layer solar cell with 6.4% efficiency
The lightweight and flexible cell was built by Estonian researchers with microcrystalline powders. The device is claimed to be the most efficient solar cell fabricated with a semiconductor compound known as Cu2CdGe(SxSe1-x)4.Scientists at Estonia s Tallinn University of Technology (TalTech) have developed a monograin layer solar cell based on a semiconductor compound made of microcrystalline powders that is known under the chemical formula Cu2CdGe(SxSe1-x)4. The cell was fabricated with a very tiny absorber based on monograin powders that are 10-30µm thick, which the researchers said compares .

New design for antireflective coating in multijunction solar cells
Scientists in Madrid investigated the use of antireflective coatings in multijunction solar cells, drawing several conclusions that could further improve the efficiency of these cells. Their approach could improve on current antireflective coatings, particularly for high-efficiency multijunction cells, using methods and materials already proven in mass production.Improvements in one area of a PV system often place new requirements on another, as has been demonstrated in the past year by the rapid rise of larger silicon wafer formats. For anti-reflective coatings (ARCs), now widely applied to frontside .
