n-Type CdSnP2 crystals, grown from Sn melt, were characterized by X-ray diffraction, Mőssbauer spectroscopy and Hall measurements. They were employed as electrodes in a CdSnP2/aqueous polysulfide photoelectrochemical cell, for further eletro-optical characterization by current-voltage, capacitance-voltage and spectral response measurements. The photoelectrochemical data agree well with those obtained from solid state measurements and with literature data. The n-CdSnP2/polysulfide system is sufficiently stable and efficient (up to 20% quantum efficiency at 650 nm under reverse bias) for materials characterization, but photocorrosion, leading to the formation of CdS at the surface, limits its use as a practical regenerative solar cell, for long-term application.
