A new hybrid solar energy converter generates electricity and steam with high efficiency and low cost, researchers report.

A new device for blackouts improves energy delivery between home solar-power systems and the electrical grid, report researchers.

What if solar panels could generate power when there's no sunlight? It could be possible with the right solar cell, reasearchers say.

Defects could actually make batteries better, which could affect transportation, electronics, and solar power energy storage, researchers report.

"What we have found is that sometimes when you design for recyclability, you give up on durability, and when durability is the goal, recyclability is sacrificed."
