The electrical and optical properties of thin films of K-Sb-S prepared by spraying a solution of antimony potassium tartrate and thiourea onto heated conducting and non-conducting glass substrates are described. The polycrystalline films produced at an optimum spray rate and at different substrate temperatures were characterized for semiquantitative analysis. The films show variation in thickness with substrate temperature. Photoelectrochemical cells formed with the K-Sb-S film electrode, 0·5 M ferrocene in dimethylsulphoxide as the electrolyte and carbon as the counterelectrode were studied for their current voltage characteristics in dark and in light. Variation of short circuit current and open circuit voltage with light excitation intensity is also described.

The performance of the redox storage battery based on the Fe-Cr redox couple is studied in charging and discharging modes of the system. The stability of each charged species is determined by measuring the variation of half-cell potential with time. The spectra of the electrolytes are recorded before and after charging of the system. The effect of atmosphere on the charged species has also been investigated.
