Chinese scientists push selenium solar cells beyond 10% efficiency
Researchers at the Chinese Academy of Sciences have achieved a world record for selenium solar cells, reaching 10.3% efficiency, surpassing the 10% threshold for the first time. This milestone was made possible through optimized charge-selective contacts, light-driven crystallization, and post-deposition annealing, resulting in stable devices with a 1.03 V open-circuit voltage. The breakthrough in selenium solar cells, known for their wider bandgap and high efficiency potential, demonstrates the success of careful optimization and strategic combinations by the research team. The device also exhibited minimal efficiency loss after 1,000 hours of testing, highlighting its promising future in the development of efficient solar energy solutions.

Plug-in solar gains momentum as states confront energy costs
Several states in the U.S. are exploring legislation to support plug-in solar energy systems, also known as balcony solar, which have been successful in Germany. This green technology is being tested and certified for use in American homes, offering a cost-effective solution for rising electricity costs. The bipartisan opportunity for climate advocates in the U.S. comes at a time when subsidies for other renewable energy options have been repealed under the current administration. This shift towards plug-in solar could be a significant step towards achieving climate solutions and reducing carbon emissions.

Governments defend energy transition as US snubs renewables agency
The United States' withdrawal from IRENA has raised concerns about funding, but discussions are ongoing to fill the potential financial gap. The global transition to clean energy is driven by economic, national security, and strategic reasons, with significant investments being made in renewable energy. However, more support is needed for African countries and small island developing states to access clean energy finance. IRENA aims to triple renewable energy capacity by the end of the decade and is working on a roadmap to transition away from fossil fuels, to be presented at COP31 in November. They are also considering a target for electrification consistent with this plan.
