Description
Hryhorii Parkhomenko and co-authors blast flexible light sensors with protons to see if they could work in space. The detectors are made from perovskite films laid down by slot-die coating, a printable method suited to large areas, and they sense light from both faces. Radiation tolerance is the open question for such devices on satellites.
Short, intense proton pulses at two dose levels cut the sensors' quantum efficiency by roughly a third at low dose and about half at high dose. Sensitivity fell in step, with the metal-sandwich face suffering more than the plastic face. Even so, the team judges the damage modest for such exposure, backing printable perovskite detectors for aerospace and high-energy physics duty.
