Title:
DYE SENSITIZED SOLAR CELL AND DYE SENSITIZED SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2007/083461
Kind Code:
A1
Abstract:
This invention provides a dye sensitized solar cell comprising a support formed of
a light transparent material, and an electroconductive layer, a photoelectric conversion
layer formed of a porous semiconductor layer having a dye adsorbed thereto and
filled with a carrier transport material, and a counter electrode comprising
a counter electrode electroconductive layer alone or a counter electrode comprising
a catalyst layer and a counter electrode electroconductive layer, each stacked
on the support. The photoelectric conversion layer is in contact with the counter
electrode. The porous semiconductor layer constituting the photoelectric
conversion layer has a multilayer structure of at least two layers different
from each other in light scattering properties. The two or more layers constituting
the porous semiconductor layer are stacked in the order from low to higher light
scattering property level layers from the light receiving face side of the dye
sensitized solar cell.
