CoSe hollow spheres composed of nanoparticles as the counter electrode in dye‐sensitized solar cells can not only efficiently catalyze the reduction of I 3 − to I − but also reflect the transmitted light through the photoanode back to dye molecules for higher light‐harvesting efficiency, achieving power conversion efficiency of 10.35% compared to 8.57% for Pt‐based solar cells.
