We report a promising photoanode material of Fe2O3/BiOI for efficient photoelectric conversion in solar cells, which was fabricated with BiOI attached to a one-dimensional Fe2O3 nanorod array. The two semiconductors of p-type BiOI and n-type Fe2O3 formed a heterogeneous structure for efficient charge separation. The highest open circuit voltage and short circuit current of the solar cell can reach 0.41 V and 4.89 mA/cm2, respectively. This study opens an available field to develop low-cost and environmentally friendly photoelectric materials for solar cells. [ABSTRACT FROM AUTHOR]
