Researchers at Linköping University have mapped how energy flows in organic solar cells, something that previously had been unknown. The results, which can contribute to more efficient solar cells,...
A technology to realize ‘urban gold mining’
May 17, 2022 (Nanowerk News) In South Korea, which relies on imports for 99.3% of metal resources, the per capita consumption of metal resources is the highest in the OECD (Organization for Economic Co-operation and Development), and consumption of precious metals in various industries such as renewable energy, healthcare, and...
Major infrared breakthrough could lead to solar power at night
May 17, 2022 (Nanowerk News) The sun’s enormous energy may soon be harnessed in the dark of night following a significant advance in thermal capture technology. Solar radiation heats the earth’s crust significantly during daylight hours, but that energy is lost into the coldness of space when the sun goes...
Upcycling strategy turns discarded solar cells into thermoelectrics
May 16, 2022 (Nanowerk Spotlight) Among the many renewable energy sources, waste heat has enormous potential given the fact that machines and electronic devices emit massive amounts of it. This waste heat could be recaptured by so-called thermoelectric materials, which use temperature differences to generate electrical energy. Simply put, when...
