Tests Measure Solar Panel Performance Beyond Established Standards

Photovoltaics used in solar panels are sensitive to environmental factors and often suffer degradation over time. International Electrotechnical Commission standards for accelerated degradation do not include field tests. While some testing facilities have made data available, much of the data needed to make business decisions for PV is not available publicly.

Big Advancements Ahead in Lead Battery Energy Storage Innovation

A three-year scientific research project currently underway at the U.S. Department of Energy's Argonne National Laboratory is showing promising results to unlock the untapped potential of lead batteries. Lead batteries currently supply over 70% of the world's rechargeable battery energy needs. Yet, possibilities exist to expand their performance to meet growing energy storage and transportation demands.

Building a Better Battery with Machine Learning

Designing the best molecular building blocks for battery components is like trying to create a recipe for a new kind of cake, when you have billions of potential ingredients. The challenge involves determining which ingredients work best together — or, more simply, produce an edible (or, in the case of batteries, a safe) product.

Ripple in Flexible Material Could Improve Electronic Properties

Two-dimensional materials — those either only an atom or layer thick — display a number of interesting properties and could form the foundation for a range of new devices. One of these materials, molybdenum disulfide, has shown an unusual flexibility that could make it attractive as a semiconducting component of bendable electronics.

Machine Learning Algorithms Help Predict Traffic Headaches

Urban traffic roughly follows a periodic pattern associated with the typical "9 to 5" work schedule. However, when an accident happens, traffic patterns are disrupted. Designing accurate traffic flow models, for use during accidents, is a major challenge for traffic engineers, who must adapt to unforeseen traffic scenarios in real time.

Shedding New Light on the Charging of Lithium-ion Batteries

Exposing cathodes to light decreases charge time by a factor of two in lithium-ion batteries. Researchers have reported a new mechanism to speed up the charging of lithium-ion batteries for electric vehicles. Simply exposing the cathode to a beam of concentrated light -- for example, the white light from a xenon lamp -- lowers the battery charging time by a remarkable factor of two or more. If commercialized, such technology could be a game changer for electric vehicles.
