Title:
PHOTOELECTRIC CONVERSION ELEMENT AND SOLAR CELL USING SAME
Document Type and Number:
WIPO Patent Application WO/2007/043408
Kind Code:
A1
Abstract:
A photoelectric conversion element having improved photoelectric conversion
efficiency is provided. Furthermore, a solar cell employing such photoelectric
conversion element is also provided. The photoelectric conversion element
is composed of a photoelectric conversion layer (31) composed of a porous semiconductor
layer (11) adsorbing dye, a carrier transporting layer (4) and a pair of electrodes
(3, 7). The total haze ratio of the porous semiconductor layer (11) of the photoelectric
conversion layer (31) in a near infrared region is 60% or more but not more than
95%. Especially when the porous semiconductor layer (11) is composed of a plurality
of layers, the haze ratio of the porous semiconductor layer in the near infrared
region furthest from a light incoming side is preferably 60% or more but not more
than 95%.
