SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING THE SAME

A solid electrolytic capacitor according to one aspect of the present disclosure comprises: an anode body made of a valve metal; a dielectric layer formed on the anode body; and a solid electrolyte layer formed on the dielectric layer. The solid electrolyte layer includes: a first conductive polymer layer formed on the dielectric layer and heterogeneously doped with a single molecule dopant; a barrier layer formed on the first conductive polymer layer; and a second conductive polymer layer formed on the barrier layer and composed of a self-doped conductive polymer including a plurality of side chains including functional groups capable of being doped. The barrier layer blocks migration of the self-doped conductive polymer from the second conductive polymer layer into the first conductive polymer layer and/or blocks migration of the self-doped conductive polymer from the second conductive polymer layer into the pores of the porous anode body. 根据本公开一个方面的固体电解电容器包括：由阀金属制成的阳极体；形成在阳极体上的介电层；以及形成在介电层上的固体电解质层。固体电解质层包括
