"GdPO4-GC:Eu3+/Pr3+ absorbs UV and re-emits...  UV likely causes Pr3+ ion to be transferred to Gd3+ ion, releasing some of it before transferring rest to Eu3+ ion, undergoing down transition to lower energy states, emitting visible light... thin transparent GdPO4-GC:Eu3+/Pr3+ layer shields from UV(preventing perovskite degradation) and feeds it additional light... more sensitive to UV, stable, rugged (hard texture good for outer space)... overcomes limitations of perovskite and amorphous-silicon carbide solar cells"
