Researchers have developed a new hybrid device -- pairing silicon with organic, carbon-based molecules -- that can convert blue photons into red photons, paving the way for more efficient solar energy conversion.
Silicon's electronic properties make it a popular choice for a variety of technologies. The material, one of Earth's most abundant, is used to make everything from semiconductors to solar cells. But silicon isn't great at turning light into electricity.
While silicon can convert red photons into electricity just fine, its attempts to convert blue photons, which carry twice as much energy as red photons, yields mostly wasted thermal energy.
For the new device, engineers paired silicon with a carbon-based material called anthracene that converts blue photons into red photons, which the silicon can more easily convert into electricity.

Yes that what tfa says. Btw law of conservation of energy is by no means the gospel you and others think it is.

I think Mrs. Noether wants to have a word with you.
