Abstract:
The present invention is to suggest a structure capable of improving performance and durability of a quantum dot solar cell among sensitized solar cells. Durability is improved by preventing direct contact with electrolytes by introducing a protective layer on an upper part of a quantum dot light-sensitive group in order to reduce deactivation of the quantum dot solar cell due to the electrolytes. Efficiency can also be improved by further introducing a dye light-sensitive group to the protective layer.
