Mirrors to improve dye sensitised solar cell performance

Mirror-like nanoparticles can boost the efficiency of solar cells. Scientists in Australia coated a solar cell’s TiO2 photoanode with cubic cerium oxide nanoparticles. The nanoparticles’ large mirror-like facets are good at scattering light back onto the TiO2 nanoparticles, resulting in a 17.8% improvement in the power conversion efficiency compared to regular dye sensitised solar cells.
