Organic photovoltaic solar cells could withstand harsh space environments

11 Feb 2025 Isabelle Dumé
Two images from a simulation showing protons at energies of 100 keV and 10 keV penetrating different layers of a solar cell. Both images mark out the six layers of the solar cell, with the organic layer as the third layer down. The proton penetration is shown white on the black background, and for the 100 keV image, it takes the appearance of a pine tree in a snow storm as the protons trace out a cascade of triangles through all of the solar cell's layers. The 10 keV protons image looks like a hairy-looking ball concentrated in the silver top layer with stray strands stretching into the organic layer

Carbon-based organic photovoltaics (OPVs) may be much better than previously thought at withstanding
