COMPOSITE PROTECTIVE LAYER FOR PHOTOELECTRODE STRUCTURE, PHOTOELECTRODE STRUCTURE COMPRISING THE COMPOSITE PROTECTIVE LAYER FOR PHOTOELECTRODE STRUCTURE AND PHOTOELECTOCHEMICAL CELL INCLUDING THE SAME

摘要

Disclosed are a composite protective layer for a photoelectrode structure, a photoelectrode structure comprising the same and a photoelectochemical cell including the same. The composite protective layer for a photoelectrode structure includes a chemical protection layer; and a physical protection layer. The chemical protection layer has corrosion charge per unit time, 0.1 C/cm2 or less in a water decomposition potential. The physical protection layer has conductivity and moisture transmission, 0.001 g/m2/day or less.
