The photon‐to‐hydrogen conversion efficiency can be calculated from the equation:η= [J× (1.23– Vbias)]/Pin whereJis the photocurrent density (mA cm−2) Vbiasis the applied external bias which is obtained asVbias=ς(Vmeas– Voc) whereVmeasis the electrode protential at whichPinwas measured Vocis the electrode potential at open circuit in the same electrolyte and under the same illumination of light andPinis the incident light intensity in mW cm−2(100 mW cm−2in this case).
