Photocurrent comparison
The following charts compare the photocurrent differentials (i.e. light current - dark current) obtained from NBEXP0017 and NBEXP0018. The x-axis values 1-9 correspond to the following sequence: 1 = FTO, 2 = Sample 1, 3 = Sample 2, ... 9 = Sample 8. The 'Pulse #' in the graph titles refer to the on-off light sequence; Pulse 1 is the 1st on/off cycle, pulse 2 the 2nd on/off cycle, etc.

The graphs show that photocurrent generation ability of RGO exceeds that of graphite at the highest carbon loadings. In fact, the RGO seems to be on an upwards trend while the graphite seems to be on a downwards trend; a repeat of the experiments at higher carbon loadings would probably show a more extreme difference.

Photovoltage comparison

Adding more carbon causes a positive voltage shift for both RGO and graphite samples.
