Streamlining CdSe/CdS PEC characteristics using Cd metal substrate

Ti or Ni metals – used conventionally as substrates – were substituted with Cd metal to improve the output characteristics and the reproducibility of the CdSe/CdS PEC (photoelectrochemical converter – photoelectrochemical solar cell). This approach proved valid and the following mean results were obtained: light to electric energy efficiency – Ca. 4.5% filling factor – approx. 0.37, open-circuit voltage – around 500 mV and short-circuited current density – about 35 mA/cm2 at light illumination intensity of 70 mW/cm2.
