Upconverter loaded MoS counter electrode for broadband dye-sensitized solar cell applications.

An interesting approach of including an upconverter in the MoS counter electrode can yield broadband light harvesting Pt-free DSSC assembly. Here different upconverter (UC) nanoparticles (Yb, Er incorporated NaYF, YF, CeO & YO) were synthesized and loaded in MoS thin film by hydrothermal method. The inclusion of UCs in MoS films exposed without any secondary formation of upconverters and the uniform deposition of the films are confirmed through XRD and FESEM analysis respectively.
