A strategy for utilizing hollow polyoxometalate nanocrystals to improve the efficiency of photovoltaic cells

We provide a new strategy to use PW12 with different morphology to design promising photoanode materials, and apply them to the DSSCs to restrain charge recombinationsthe. Meanwhile, the η of DSSCs with PW12-H@TiO2 is up to 8.06%, which is 34% higher than those based pristine TiO2 (η = 6.00%).551
