Preparation and Performances of Sensitized Photocatalyst Systems for Solar Cells

Abstract

Dye-sensitized solar cells (DSSCs) are promising photo-voltaic devices for solar energy conversion. The design of DSSCs includes the configuration of efficient anodes, sensitizer and counter electrode. In this thesis, a series of carbon-based nanomaterials (carbon quantum dots, nanodiamonds and their modified forms) have been developed and successfully applied as sensitizers for DSSCs. Moreover, metal-encapsulated carbon nanotubes and nitrogen-doped graphene have also been prepared and demonstrated their potential as counter electrodes for DSSCs.
