AI software assists design of new material for solar cells
29 May 2018 at 7:35am
Researchers have used machine learning to design new polymers for organic photovoltaics (solar cells). After mining data from previous studies, they input the physical properties of polymers, together with the resulting solar cell efficiencies, into a Random Forest model to statistically predict the effectiveness of new materials. This informatics-based screening, combined with traditional knowledge-guided design, could vastly accelerate solar cell development compared with current trial-and-error experimentation.

How greener grids can stay lit
24 May 2018 at 11:15am
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
