NOVELTY - A solid-state electrolyte comprises a matrix component including a low-molecular weight liquid crystal material(s), or a polymer liquid crystal material from a siloxane polymer liquid crystal material or an acryl polymer liquid crystal material, and a matrix polymer.    USE - The solid-state electrolyte is for a dye-sensitized solar cell (claimed).    ADVANTAGE - The solid-state electrolyte provides solar cell, which does not require the use of a solvent and a sealing agent, as do conventional dye-sensitized solar cells using a liquid-state electrolyte, thus realizing a simple fabrication process; and which can exhibit much higher energy conversion efficiency (8.9%) than conventional dye-sensitized solar cells. A dipping process is adopted in the formation of an electrolyte layer to maximize surface contact between the dye and the electrolyte layer, to effectively induce an increase in photocurrent and increasing the interfacial adhesion between the dye-adsorbed oxide layer and the electrolyte. The dye-sensitized solar cell has superior stability to a conventional liquid-state dye-sensitized solar cell.    DETAILED DESCRIPTION - A solid-state electrolyte comprises a matrix component including a low-molecular weight liquid crystal material(s) of formula R1-(p-Ph)2-C?=N (I), or a polymer liquid crystal material from a siloxane polymer liquid crystal material of formula (H3C)3Si-(O-Si(CH3)((CH2)m-O-p-Ph-R2))n-O-Si(CH3)3 (II) or an acryl polymer liquid crystal material of formula -(H2C-C(R4))n-C(=O)-O-(CH2)m-A-(p-Ph)2-C?=N (III), and a matrix polymer; and an electrolyte composition.    R1=1-20C alkyl group, 1-20C alkoxy group, or 1-20C alkylaryl group;    R2=optionally substituted aryl group;    m=1-20;    n=greater than or equal to10;    R4=H or 1-10C alkyl group;and    A=ether, ester, or ketone group.    An INDEPENDENT CLAIM is also included for a dye-sensitized solar cell, comprising a first electrode (1002); a second electrode (1005) facing the first electrode; an oxide layer (1003) having a dye adsorbed on it, and formed between the two electrodes; and a solid-state electrolyte layer (1004) formed adjacent to the oxide layer including a matrix component.
