All-perovskite tandem solar cell with dipolar passivation achieves 30.1% efficiency
Researchers in China have developed a dipolar passivation method that reduces defects and improves charge transport in solar cells based on narrow-bandgap tin lead perovskite, enabling the fabrication of all-perovskite tandem solar cells with efficiencies of around 30% and enhanced stability. The dipolar passivation strategy strengthens the ohmic contact, promotes efficient hole injection into the hole transport layer, and repels electrons from the perovskite interface, reducing non-radiative recombination and carrier transport losses. The cell achieved a power conversion efficiency of 24.9% and retained around 87% of its initial efficiency after 1,025 hours, showing promising long-term stability. The researchers aim to further improve the dipolar passivation method for enhanced stability in tandem devices, contributing to the ongoing efforts to develop more efficient and sustainable solar energy solutions.

Australia’s most advanced renewable grid is its most secure, but NSW must scramble as it nears “no coal” scenario
South Australia is leading the way in renewable energy with a 75% share of wind and solar, making it the most secure state grid in Australia. The state has successfully transitioned away from coal-fired power stations and has implemented innovative solutions such as the Tesla big battery and synchronous condensers. South Australia is on track to reach 100% net renewables and will be able to run its grid without gas plants. However, other states like NSW and Victoria are facing challenges with the closure of aging coal-fired generators and are scrambling to secure replacement capacity for critical grid services. AEMO warns of potential risks and the need for further action to ensure system stability in the future. The closure of coal-fired power plants in Australia, such as the one in NSW, is expected to lead to a "credible no coal scenario" by 2031/32. Similar closures are planned in Victoria and Queensland in the coming years. The transition to a high renewable grid is essential for Australia to meet its 2030 and 2035 climate targets. AEMO warns that new investments and reforms are needed to maintain system security during this transition, including utilizing renewable energy sources like rooftop solar. Industry and governments are working together to manage the transition points and ensure system security.

Construction kicks off on major upgrade of transmission links to host renewables and clear path for coal exit
Construction has begun on the Clean Energy Link – North project in Perth's northern suburbs, the largest investment in Western Australia's electricity transmission infrastructure in over a decade. The project includes major upgrades to the northern section of the South West Interconnected System (SWIS) to facilitate the addition of renewable energy resources, doubling capacity in some sections and enabling the flow of wind and solar energy. This project is part of the state government's plan to exit State-owned coal by 2030 and make Western Australia a renewable energy powerhouse. The North project is set to be completed by the end of 2027, creating over 400 jobs and contributing to the state's transition towards clean energy solutions.

Photonic curing could accelerate transition to copper-metallized solar cells
Researchers in the United States have developed a photonic curing technique using laser sintering to improve the copper metallization of solar cells by reducing oxidation. This process produces dense, low-porosity copper layers with strong adhesion to indium tin oxide, achieving low bulk and contact resistivity. The technique allows for rapid, localized heating of copper pastes on temperature-sensitive substrates without causing thermal stress. The researchers aim to reduce copper consumption and improve the efficiency of solar cells through this innovative method, which is scalable and compatible with high-volume photovoltaic manufacturing. This new technique for solar cell manufacturing using photonic curing of copper inks could provide a pathway to scalable copper metallization for solar cells, as presented in a paper published in physica status solidi (PSS) by a research team including academics from the University of Delaware.

Australia doesn’t have to choose between energy affordability and emission reductions
IEEFA has found that improving energy affordability in Australia does not have to be incompatible with emissions reduction targets. The country's aging coal fleet and network assets need to be replaced, with renewables backed by storage and transmission being the most cost-effective option. Gas-based generation has become increasingly uncompetitive, with high prices and declining consumption. Contrary to misconceptions, renewables have not been driving electricity prices up, with high gas and coal prices, coal outages, and network costs being the main factors. Faster approval processes and better market regulations are needed to ensure a smooth transition to cleaner energy sources. Reforms to improve competition, allow distributed energy resources to compete, and promote energy efficiency, electrification, and flexible demand are key to lowering household energy bills. Transitioning to modern electric alternatives, such as heaters and hot water systems, along with solar and battery systems, can significantly reduce costs. Industrial energy efficiency and electrification also offer major savings. The key pathways to improve energy affordability are aligned with net zero emissions goals, emphasizing the need for accelerated deployment of renewables, energy efficiency, and electrification. The narrative that lowering bills and cutting emissions are mutually exclusive is false.
