Researchers at the University of Cambridge have discovered photovoltaic properties in an organic semiconductor molecule called P3TTM, which has an "open-shell" character due to unpaired electrons, allowing for efficient photon-to-charge conversion in solar cells. The new material enables the fabrication of solar cells from a single, low-cost, lightweight material, potentially increasing overall efficiency. The findings were published in the study "Intrinsic intermolecular photoinduced charge separation in organic radical semiconductors" in Nature Materials, highlighting a promising advancement in solar cell technology for climate solutions experts.

C40 cities on track for 50 million good green jobs by 2030 as mayors deliver on World Mayors Summit job creation pledge
C40 Cities are committed to delivering 50 million green jobs by 2030, with a focus on inclusive economic growth and city-led climate action. The recent data highlights the importance of creating good green jobs in sectors like waste management, construction, transport, and energy to reduce greenhouse gas emissions and improve well-being. Mayors are accelerating investments in sustainable initiatives and working towards a just transition, recognizing the central role of cities in driving global climate and economic progress. Efforts are being made to address gender and equity gaps in green jobs, with a focus on providing fair wages, safe working conditions, and stable employment for all workers. The World Mayors Summit in Rio de Janeiro will further emphasize the need to scale up finance for city-led climate action and strengthen skills training to drive the transition to a green economy.
