In the News – The Latest in Energy and Materials PROTOYPE NUCLEAR BATTERY: Could this Diamond / Nickel-63 Battery be the Future of Power Generation? Nuclear batteries, or betavoltaics, have recently stepped back into the light with the development of a battery producing 3,300 milliwatt-hours of energy per gram, ten times more than the specific energy of commercial chemical cells. The cell was designed at the Moscow Institute of Physics and Technology, composed of diamond and nickel-63.

However, most are either unstable at the high temperatures that solar cells operate at, or contain lead, which is highly toxic. Recent developments in America and Japan have provided neat solutions to these complications, which you can read more about here: Researchers Discover New Lead-Free Perovskite Material for Solar Cells >> and here: Improving Prospects of Perovskite Solar Cells >> COMPUTATIONAL ASSISTANCE: Screening More Photovoltaic Materials with AI Software In the search for new and efficient materials for solar applications, to save time and effort, scientists are turning to computational methods to screen for well-matched solar materials. A team of scientists at Osaka University used machine learning to build a model predicting the efficiency of potential new organic photovoltaic devices, gathering data from around 500 studies on ~1200 organic photovoltaic materials.
