2-D Mxene flakes as potential replacement for both TCO and Pt layers for Dye-Sensitized Solar cell

The counter electrode (CE) containing catalyst layer and transparent conducting oxide (TCO) is by far the most expensive components in Dye sensitized solar cells (DSSC) due to use of rare earth element such as Pt. potential replacement both TCO Pt-based would essentially pave way mass commercialization technology DSSC. In this investigation, an attempt has been made replace Pt with a single delaminated 2-D MXene (Ti3C2) being produced leaching method which acted catalyst. Furthermore, thickness Ti3C2 optimized for maximum conversion efficiency. TCO-Pt-free based CEat optimum exhibited remarkable 8.68% efficiency outperforming standard TCO-Pt-based CE 4.03%. high conductivity, available catalytic cites structure, good activity towards iodide/triiodide electrolyte.
