Diamond-based circuits can take the heat for advanced applications
10 Apr 2018 at 8:09am
When power generators transfer electricity, they lose almost 10 percent of the generated power. To address this, scientists are researching new diamond semiconductor circuits to make power conversion systems more efficient. Researchers have now successfully fabricated a key circuit in power conversion systems using hydrogenated diamond. These circuits can be used in diamond-based electronic devices that are smaller, lighter and more efficient than silicon-based devices.
High efficiency solar power conversion allowed by a novel composite material
9 Apr 2018 at 11:47am
A composite thin film made of two different inorganic oxide materials significantly improves the performance of solar cells. Researchers have developed this material which combines two crystal phases comprising the atomic elements bismuth, manganese, and oxygen. The combination of phases optimizes this material's ability to absorb solar radiation and transform it into electricity. The results are highly promising for the development of future solar technologies, and also potentially useful in other optoelectronic devices.
