Problems solved by technology

[0004] However, in the dye-sensitized solar cell disclosed in JP-A-2010-55935, the corrosion resistance to the electrolyte of the dye-sensitized solar cell element can be maintained by the metal substrate made of Ti, Ti alloy or stainless steel, On the other hand, since Ti, titanium alloy, or stainless steel constituting the metal substrate has relatively high electrical resistance, there is a disadvantage that electrical loss is likely to occur on the metal substrate
Therefore, there is a problem that the power generation efficiency of the dye-sensitized solar cell decreases.
