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

Solar panel costs have dropped lately, but slimming down silicon wafers could lead to even lower costs and faster industry expansion.

MIT researchers review renewable energy and carbon pricing policies as states consider repealing or relaxing renewable portfolio standards.

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

Researchers had all but given up on emerging organic solar cell technology, but chemical tweaks brought them back from the brink. Here's how it worked.

A new kind of semiconductor made from barium zirconium sulfide instead of silicon could pave the way for better solar panels, LEDs, and sensors.

MIT study finds that challenges in measuring and mitigating leakage of methane, a powerful greenhouse gas, prove pivotal.

New material should be relatively easy to produce at an industrial scale, researchers say.

Discovery means simpler and cheaper manufacturing methods are actually beneficial for the material’s use in next-generation solar cells or LED lighting.
