A laminated film comprising a porous semiconductor layer, a transparent conductive layer and a transparent plastic film, wherein

Dye-sensitized solar cell, and electrode and laminated film for the same

A laminate for dye-sensitized solar cell comprising a plastic film of which the thermal shrinkage in the machine direction thereof when heat-treated at 200&#xb0; C. for 10 minutes is from &#x2212;1.5 to +0.5%, and a transparent conductive layer provided on the film, which comprises essentially indium oxide with zinc oxide added thereto and has a surface resistivity of at most 40 &#x3a9;/square, may give a highly-durable and flexible, dye-sensitized solar cells having high photovoltaic power generation efficiency.

Laminate for dye-sensitized solar cell, electrode for dye-sensitized solar cell and method for producing it

An oriented polyimide film of high strength and a production process therefor. The process basically comprises stretching a gelled film and then imidating the film. The gelled film is formed by introducing a polyamic acid solution into a condensation agent solution. The gelled film is swollen with a solvent at the time of stretching.
