More light for solar cells: Novel alloy provides efficiency boost

[Redaktion]

Instead of improving the electricity yield of existing technology, a research team has been able to convert light into electricity that has not yet been used. Efficiency is expected to increase by two thirds - and all without rare-earth elements.

Indeed good news!

"which is already around 5 cents with current technology with current technology. "

Proof read much?

LOL!

There's a difference between test bed efficiency and real world due to weather. The reason solar cells for space are so efficient is the solar spectrum doesn't change and the multi-junction cells are optimized for the AM0 spectrum. Put the same cells down here on earth and they are only reach peak efficiency around solar noon on blue sky days.
