Abstract

A polymeric compound solid electrolyte for dye sensitization batteries and method for making same, including a polymer matrix, a redox couple, a silicone hydride coupling agent containing isocyanate functional groups and functional groups capable of complexing with inorganic sol particles after hydrolyzing, and a metal alkoxy compound generating inorganic sol particles after hydrolyzing, wherein, the inorganic sol particles are complexed with the polymeric matrix through sol gel in situ compounding. In the inventive polymer solid electrolyte, the inorganic sol particles are uniformly dispersed in the polymer matrix, the polymer solid electrolyte has good heat stability, simple and unique preparation method, no requirement of complicated equipment, capability of effectively resolving the packaging problems of sensitization batteries, and good application foreground in the field of dye sensitization batteries.

Description

technical field

[0001] The invention relates to a dye-sensitized solar cell, in particular to a polymer solid electrolyte for a dye-sensitized solar cell and a preparation method thereof. Background technique

[0002] According to the different electrolyte states used in dye-sensitized nano-thin film solar cells, they can be divided into three categories: liquid electrolyte batteries, quasi-solid electrolyte batteries and solid electrolyte batteries. Liquid electrolyte system Liquid electrolyte has been widely studied due to its fast diffusion rate, high photoelectric conversion efficiency of batteries, easy design and adjustment of composition, and good permeability to nanoporous membranes. In 1991, M. The research team first made a breakthrough in this electrolyte system, which consists of three components: a redox couple, an organic additive, and an organic solvent. The solute in the electrolyte is mainly composed of redox pairs with good reversibility, generally conta...
