World's Most Efficient

The dynamic duo of silicon and perovskite continue their rampage through the solar cell industry. Researchers at KAUST have developed a new silicon/perovskite tandem solar cell with a record-breaking efficiency.

Perovskite and silicon are proving to be a formidable duo in the world of solar cells, and now they’ve hit a new record efficiency. A team at Helmholtz Zentrum Berlin (HZB) have developed solar cells with an efficiency of over 32%.

Researchers at the National Renewable Energy Laboratory have broken the world record for solar cell efficiency. Reaching almost 40 percent, the new device boasts the highest efficiency recorded for any type of solar cell in real-world conditions.

Researchers have developed a photovoltaic device that has an external quantum efficiency of 132 percent. This impossible-sounding feat was achieved using nanostructured black silicon, and could represent a major breakthrough for solar cells.

The world of architecture figuratively doffed its cap to Earth Day on Monday with the opening of the Bullitt Center in Seattle, claimed to be the world's greenest commercial building.

Back-to-back announcements from Green Ray LED and Philips show signs that there is now clear water between LED lights and fluorescent lights so far as energy efficiency is concerned.

Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity.
