Semiconductor-septum solar rechargeable storage cells

Abstract We have investigated the production of energy as well as its storage using semiconductor-septum solar cells using CdIn2S4 thin films. The thin films of CdIn2S4 as a septum have been deposited by using spray pyrolysis technique on to the stainless steel substrates. The semiconductor-septum solar rechargeable (SC-SEP) storage cell is engineered with the configuration C|1 M polysulphide|n-CdIn2S4|stainless steel||1 M FeCl3 or 1 M K4Fe(CN)6|C. The study of charging and discharging modes are exhaustively argued. The FeCl3 based storage cell has superior efficiency for solar conversion energy than other electrolytes. The deposited CdIn2S4 was successfully used as a working electrode in semiconductor-septum storage cell.
