Semiconductor-septum solar rechargeable storage cells

▶ We report on the spray deposited n-CdIn2S4 thin films on to the stainless steel substrates and their use as septum electrode in redox storage cells. ▶ These films are used as a separator in the rechargeable storage cell. ▶ The renewed efforts are directed towards the combinations of n-CdIn2S4 and various electrolytes are discovered that could affect the stable conversion of light into electricity as well as storage at these systems. ▶ The charging of SC-SEP redox storage cells upon illumination and their subsequent electrochemical discharge are studied.
