ENHANCING ALTERNATIVE SOLAR MATERIALS: Lead-Free and Heat-Stable Perovskite Materials

Perovskites have emerged in solar cell research as a promising alternative to silicon-based photovoltaics with high efficiencies and the functionality to create thin films of the material. 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.  Find out more here: AI Software Assists Design of New Material for Solar Cells >>
