Printing a 30% solar cell
Perovskite-silicon tandem solar cells are the leading candidate to push panels past the limits of silicon alone, but many record cells are made with lab-scale methods that do not translate easily to factories. According to TaiyangNews, researchers at Germany's Karlsruhe Institute of Technology (KIT) have now demonstrated a perovskite-silicon tandem cell with 30.2% efficiency using a process built around inkjet printing, which they describe as the first time such a cell...

Revolutionary Fully Spherical & Portable Camera
Imagine having a 360-degree experience to capture, explore with a device that can fit snugly in your hand.
The Theta camera, from the Japanese firm Ricoh, is the world's first handheld camera that takes fully spherical photos with just one press of a button.
The device fits comfortably in the palm of a hand, similar to a remote control. Its twin-lens system captures the scene around, above and below the device.
The shutter button is positioned below the lens making it easy to take the p...
