Energy news, April 2020

Scientists have discovered that impurities at grain boundaries are responsible for impeding the flow of ions through solid electrolytes.

The traps that capture charge carriers in perovskite crystals occur at the boundaries between distorted grains and pristine grains.

Researchers can monitor batteries by sending electrical pulses into them and then processing the response with a new machine-learning algorithm.

Adding a low concentration of a 2D tin-based perovskite to a 3D version in solution produces a stable and efficient photovoltaic thin film.

Triboelectric energy harvesters get a boost from Georgia Tech

A novel neural network was able to reduce the time needed to discover promising materials for a flow battery from 50 years to five weeks.

Scientists have developed an artificial photosynthesis system that utilizes nanotubes made of layers of cobalt oxide, silica and titanium dioxide.

Researchers have demonstrated that solar cells made from organic materials may be better than traditional silicon solar cells for use underwater.
