Light goes in, volts come out, you can’t explain it!

Scientists can’t explain it

Clickbait bullshit headline.

Oh look it’s explained in the article.

In this context, they created a solar panel with two faces, a lower one of crystalline silicon with the ability to attract infrared rays and an upper one of perovskite with a higher ability to attract high-energy photons due to having a narrower forbidden broadband.

The top layer is treated with 2,3,4,5,6-pentafluorobenzylphosphonic acid (yes, it is impossible to repeat it quickly) which offers higher solar panel efficiency and lead treatment. It is then combined with a SiO2 nanoparticle coated substrate that optimizes cell conversion.

Seems to be perfectly explained to me. Lead treatment means this is unlikely to be adopted in many countries.
