Researchers in Japan have developed a new material that allows solar cells to generate an amount of energy from sunlight that was previously thought impossible. The discovery, made by a team at Kyushu University, involves a special “spin-flip” emitter that can harvest energy from the Sun that is typically lost as heat. The breakthrough overcomes the long-standing limit of conventional solar cells to achieve an energy conversion efficiency of 130 per cent – opening up new possibilities for ultra-efficient solar panels.
Short-Term Energy Outlook
The activist and author of Here Comes the Sun discusses rapid advances in solar and wind power and how the US ceded leadership in the sector to its main rival
The International Energy Agency works with countries around the world to shape energy policies for a secure and sustainable future.
Wind and solar reached a record 12% of global electricity in 2022, and power sector emissions may have peaked.
Rooftop solar panels are up to 79% cheaper than they were in 2010. These plummeting costs have made rooftop solar photovoltaics even more attractive to households and businesses who want to reduce their reliance on electricity grids while reducing their carbon footprints. But are there enough rooftop surfaces for this technology to generate affordable, low-carbon energy for everyone who needs it?
