Amorphous silicon photoanodes in a nonaqueous photoelectrochemical cell show wavelength dependence of their power outputs. This behavior has been studied by maximum power spectroscopy (MPS) and compared to similar experiments with conventional short-circuit spectroscopy. The derivative maximum power output under constant chopped input power (MPS) shows dependence on the wavelength distribution in superimposed fixed beams, whereas the conventional short-circuit measurements do not. Single-crystal substrates of n-Si, n-CdSe, and n-InP do not show any differences between the spectroscopies. Rotating ring-disk electrode studies confirm the regenerative behavior of the n-CdSe and n-InP electrodes with the Fe(HOCH2Cp)2 - Fe(HOCH2Cp)2(+) couple in LiClO4/methanol solution. Fe(HOCH2Cp)2 hydroxymethyl ferrocene. 12 references.
