A stretchable, transparent solar cell with 8% efficiency

Korean scientists have unveiled a colorless device made of silicon microwire composites. The enhanced light absorption of the cell, the researchers claim, is due to the re-absorption of light by the microwires, which also benefit from an enhanced electric field.

Solving seasonal storage with aluminum cycling

Scientists at Switzerland’s University of Applied Sciences Rapperswil have demonstrated an aluminum conversion process which could be valuable for long-term renewable energy storage. Simulations suggest that by employing the process, a new multi-family building in Switzerland could meet all its energy demand from a 7-11 kWp solar system.
