Summary: PEDOT:PSS is commonly used as a counter electrode in dye-sensitized solar cells (DSSC), while PEDOT:Carrageenan has been introduced as an electrolyte. This review provides an overview of the different roles of PEDOT:PSS and PEDOT:Carrageenan in DSSC. It also describes the synthesis process and characteristics of both materials. Overall, PEDOT:PSS functions as a counter electrode by transferring electrons back to the cell and accelerating redox reactions, while PEDOT:Carrageenan as an electrolyte does not effectively regenerate the dye sensitized at the oxidized state, resulting in a lower performance in DSSC.

Summary: In this study, a type I heterojunction was formed by loading CoP on the surface of CdS, which increased the photocurrent density and solved the problem of CdS photocorrosion. The best photocatalytic performance reached 4.43 mmolg(-1) h(-1) under visible light when the loading of CoP was 10%, which was 20.1 times higher than that of CdS (0.22 mmolg(-1) h(-1)). After 5 cycles of simulated solar irradiation, the performance of 10% CoP/CdS remained at 93% of the initial test. This work provides new ideas for the design of low photocorrosion and high-performance catalysts.
