Superior back illumination current generation. a Lambert–Beer law-based simulation of light intensity in hematite film under different illumination modes (dash lines) and the measured light intensity in hematite with different thicknesses (dots) and the corresponding fitted line (solid lines). b The method used to measure the light intensity (Ix/I0). c The current density–voltage curves of Ti–Fe2O3 MC photoanode (with thickness of 1500 nm) measured under different illumination modes. d The current densities at 1.23 V vs. RHE of the Ti–Fe2O3 MC photoanodes with different film thicknesses measured under different illumination modes
