Perovskites are in line to replace pricey silicon solar cells, but they break easily. Good news: a little heat can completely heal cracks.

The next generation of greenhouses may be fully solar-powered, researchers say. But it might not work as well in chillier climates.

System achieves new level of efficiency in harnessing sunlight to make fresh potable water from seawater.

Starting with higher-value niche markets and then expanding could help perovskite-based solar panels become competitive with silicon.

Researchers are devising new methods of synthesizing chemicals used in goods from clothing, detergents, and antifreeze to pharmaceuticals and plastics.

Researchers have used femto-second laser pulses to etch nano-sized designs onto black metal, turning it into a solar energy absorber.

An MIT team has devised a lithium metal anode that could improve the longevity and energy density of future batteries.

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.

The firm says it plans to build up to 15 of the mini reactors, which can be delivered by a lorry.
