Solar Science!

In space, without the filtering of Earth’s atmosphere, objects are bombarded with increased photon-energies in the form of X-rays, gamma-rays, and charged particles, all of which cause intense radiation damage. It would be ideal not only to withstand, but to actually harvest that radiation for electrical energy.

The lab of László Forró at EPFL, led by postdocs Bálint Náfrádi and Endre Horváth, have discovered that methylammonium lead iodide (CH3NH3PbI3) can fulfill this purpose. This is a material already used in conventional perovskite solar cells, where it harvests visible-light photons that are then converted into electricity.
