Researchers use a transparent spectral converter to improve perovskite solar cells
Researchers from China's Shanghai University of Engineering Science have developed a novel solar spectral converter using a GdPO4 glass-ceramic (GC) material doped with praseodymium (Pr) and europium (Eu) ions. This technology could lead to notable boosts in performance and applicability of solar cells.
The main purpose of GdPO4-GC:Eu3+/Pr3+ is to absorb UV photons from solar radiation and re-emit them as visible light. This is possible thanks to the efficient energy transfer that happens between the ions in the material.
