摘要:
Disclosed is a solar cell characterized by using in combination at least two or more different photoelectric converters for specific wavelength ranges, each of which photoelectric converters is obtained by loading a thin film of oxide semiconductor particles formed on a substrate with a dye having a maximum absorption wavelength in a specific wavelength range or a salt of the dye.
摘要:
Disclosed is an electrolyte composition for photoelectric converters which contains a redox electrolyte pair, a room temperature molten salt and a nonionic organic solvent. This electrolyte composition for photoelectric converters is used as a charge-transporting layer in a photoelectric converter wherein a conductive support having a layer containing a dye-sensitized semiconductor and another conductive support having a counter electrode are arranged opposite to each other at a certain distance and a charge-transporting layer is sandwiched between the supports.
摘要:
The purpose of the present invention is to provide a dye-sensitized solar cell which has excellent photoelectric conversion efficiency and excellent durability. Disclosed is a dye-sensitized solar cell which comprises: a first conductive supporting body which has a semiconductor-containing layer that is sensitized by a dye; a second conductive supporting body which has a counter electrode and is disposed at a position where the semiconductor-containing layer and the counter electrode face each other at a predetermined distance; a charge transfer layer which is sandwiched between the first and second conductive supporting bodies; and a sealing agent which is provided in the peripheral portions of the first and second conductive supporting bodies for the purpose of sealing the charge transfer layer. The dye is an organic non-ruthenium dye; the counter electrode contains platinum; and the charge transfer layer is composed of an electrolyte solution that contains iodine, iodine ions and a compound which has both a thioester bond and a positively charged nitrogen atom in each molecule.
