Perovskite solar cell with 21% efficiency includes tech to prevent lead leaks

U.K. scientists have used mesoporous scaffolds based on hydroxyapatite nanoparticles – blended with titanium oxide nanoparticles – to create a mechanism that prevents lead leakage in perovskite solar cells. They claim the method captures lead ions in leaks, while also increasing cell efficiency.

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.
