After preparation Co4S3 nanocomposite counter electrode using chemical bath deposition, the amphiphilic copolymer layer was coated on the nanocomposite by spin-coating. SEM shows that Co4S3 nanoparticles are transplanted into carbon layer made by amphiphilic copolymer. Furthermore, the carbon coated Co4S3 nanocomposite counter electrode is fabrication to dye-sensitive solar cells (DSSCs) and has been confirmed to have high electrocatalytic performance toward I3- reduction due to low charge transfer resistance and high cell efficiency. The improved performance compared to the pristine Co4S3 counter electrode is due to the increased electrocatalytic area of the mesoporous carbon layer coated Co4S3 nanocomposite and the high conductive path of the carbon structure. |
