New technique lets researchers map strain in next-gen solar cells

Researchers have developed a way to map strain in lead halide perovskite solar cells without harming them. Their approach can image the grain structure of a perovskite solar cell, showing that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell. Crystal misorientation creates small-scale defects in the grain structure, which interrupt the transport of electrons within the solar cell and lead to heat loss.

Efficient hydrogen conversion via PEC water splitting using hematite mesocrystals

A research group has succeeded in developing photocatalysts that can convert an efficient level of hydrogen from water using solar light. It is hoped that methods like this one, which uses titanium-modified hematite mesocrystal-based photoanodes, could form the foundation for a commercial solar water splitting system. This would allow the clean fuel hydrogen to be produced more easily, making it a viable source of renewable energy.

Microrobots clean up radioactive waste

According to some experts, nuclear power holds great promise for meeting the world’s growing energy demands without generating greenhouse gases. But scientists need to find a way to remove radioactive isotopes, both from wastewater generated by nuclear power plants and from the environment in case of a spill. Now, researchers have developed tiny, self-propelled robots that remove radioactive uranium from simulated wastewater.

Supplier makes an Ariel Nomad off-roader fully electric

BorgWarner Ariel Nomad electricWhat happens when a dedicated fun vehicle goes electric? Supplier BorgWarner has an idea of how to create that—from the Ariel Nomad off-roader. The Ariel Nomad is essentially a jacked-up variant of the small toy builder’s Atom, itself little more than a tube-frame chassis with one of a handful of different engines thrown in the back, from…
