  CdS thin film samples were fabricated using spin coating technique on normal
glass and conductive glass substrates and annealed at different temperatures.
According to the XRD patterns of films prepared on normal glass substrates,
polycrystalline films are consist of single phase of CdS. Films synthesized on
conductive glass substrates were employed for photovoltaic measurements.
Variation of photovoltaic properties with annealing temperature was
investigated. The liquid junction photocell was measured in the electrolyte of
Na2S2O3/I2. Then, the short circuit photo current and open circuit photo
voltage were measured at room temperature under illumination and under dark
using a solar cell simulation system. Optical band gap of CdS film samples was
determined by measuring UV-visible spectroscopy.
