Problems solved by technology

However, the internal resistance in the solar cell series increases due to the increased resistance decrease in the plane direction of the transparent electrode
As a result, in the current-voltage characteristics, the fill factor (FF) and short-circuit current at the time of photoelectric conversion decrease, leading to a problem of lower photoelectric conversion efficiency

Abstract

Provided is a dye-sensitized solar cell wherein at least a catalytic layer, a porous insulating layer containing an electrolyte inside thereof, a porous semiconductor layer wherein a sensitizing dye is adsorbed and the electrolyte is contained therein, and a second conductive layer are laminated on a first conductive layer. The contact surface of the adjacently laminated porous insulating layer or catalytic layer of the porous semiconductor layer or second conductive layer has an uneven shape having a surface roughness coefficient (Ra) of 0.05-0.3 [mu]m.

Description

technical field [0001] The present invention relates to a dye-sensitized solar cell and a dye-sensitized solar cell module which can be manufactured with high yield and provide high conversion efficiency by suppressing separation of a porous insulating layer or a porous semiconductor layer from a catalyst layer or a conductive layer. Background technique [0002] Solar cells that can convert sunlight into electricity are attracting attention as an energy source that can replace fossil fuels. Currently, solar cells using crystalline silicon substrates and thin-film silicon solar cells are already in practical use. However, the former has a problem of high manufacturing cost of a silicon substrate, and the latter has a problem of increased manufacturing cost due to the need for various gases and complicated manufacturing facilities for semiconductor manufacturing. Therefore, in both solar cells, attempts have been made to reduce the cost per unit of power output by increasing...
