【Abstract】 In this paper the stability of the electrodeposited n-CdSe photoelectrodes in the Ferri-Ferrocyanide electrolyte was studied by the use of Ring-Disk electrode technique.Some factors,including,transfer of mass and the addition of NaCl in electrolyte,electrode potential,light intensity and so on,have been examined.It is pointed out that the light intensity is a key factor of effecting the stability,and shown that the catalytic surface,which acceterates the transfer rale of charge from the electrode to the electrolyle,is formed during illuminalion.更多还原
