Title:
PHOTOELECTRIC CONVERTER
Document Type and Number:
Japanese Patent JP2002222971
Kind Code:
A
Abstract:

To solve the problem that a light absorbing range of a dye used for spectral sensitizing is limited, in a dye sensitized solar battery, and the battery cannot effectively absorb a solar light from visible to near infrared region, and hence a high conversion efficiency like that of a silicon solar battery is not liable to be obtained.

A photoelectric converter comprises a conductive support, a multilayer porous photoelectric conversion layer, a conductive layer and paired electrodes. The converter having an excellent photoelectric conversion efficiency is obtained by applying a light absorption wavelength of the different dye into the respective layers of the conversion layer, sequentially applying shorter maximum absorbing wavelength from a photodetecting surface, and thereby utilizing a solar light of a wide region.
