Since the effect seems to be caused by a silicon component that isn't properly shielded from light, anything with a photon energy higher than the bandgap should do. The bandgap of silicon is 1.1eV, which means the effect should start in near-infrared.
- psgbg 12y agoWhat about glass, then that should work, right?
- jakobegger 12y agoNot sure I understand you correctly. The problem should happen with near-infrared, visible, and UV-light. Glass is transparent in the visible range, and depending on type, also in IR / UV, so glass won't work as a shield. The easiest, reliable way to shield would be wrapping in aluminum foil (also helps against RF-interference).
- psgbg 12y agoYeah you are right. I was assuming that the chips would block visible light but I forgot about UV.
