Summary: Pt nanoparticles are deposited on nickel foam via a mild displacement reaction at room temperature, producing efficient and flexible Pt counter electrodes for dye-sensitized solar cells (DSSCs). By prolonging the reaction time, the catalytic activities of the Pt counter electrode can be enhanced. The approach is facile and can be scaled up for large production of efficient flexible counter electrodes in DSSCs.

Summary: Dye-sensitized solar cells (DSSCs) are equipped with a counter electrode (CE) that collect electrons and catalyze the iodide/triiodide (I-/I3-) redox reaction. Platinum (Pt) has traditionally been used as the CE material, but its high cost and corrosion issues have prompted researchers to explore alternative materials. This review focuses on the recent advancements in using binary and ternary transition metal chalcogenides (TMC) and their composites as efficient CEs in Pt-free DSSCs.

Summary: Orthogonal Cu3SnS4 (CTS) nano-crystals were synthesized, with Cu7S4 seeds forming first at 130 degrees C and orthorhombic CTS nano-crystals forming at 180 degrees C. Selenization at 500 degrees C for 20 minutes resulted in the formation of CTSXSe4-X, which showed good conductivity and electrocatalytic activity for I-3(-) reduction when used as counter electrodes in dye-sensitized solar cells. The optimal 1.7 μm thick CTSXSe4-X counter electrode achieved a power conversion efficiency of 7.57%.

Summary: In this study, Sn-alloyed Cu2O was used as a potential alternative material for the counter electrode in dye-sensitized solar cells. It was found that Sn-alloyed Cu2O can increase the specific surface area of electron transport and decrease the band gap of the film through the annealing process. The reaction time of Sn alloying has a significant influence on the photoelectric conversion efficiency of the cells.

Summary: This study explores manganese dioxide (MnO2) and copper-doped manganese dioxide (Cu-MnO2) nanoparticles as candidates for the counter electrode (CE) material in dye-sensitized solar cells (DSSCs), aiming to provide low-cost alternatives to platinum (Pt). Experimental results show that DSSC devices fabricated with 10 wt% Cu-MnO(2) as CE exhibit better performance. The low-cost feature of using Cu-MnO(2) as CE is encouraging for further research in improving the efficiency of DSSCs with alternative CEs.

Summary: The research focused on developing alternative counter electrodes for dye-sensitized solar cells (DSSC) using simple methods. The NiCo2S4 counter electrode showed comparable photovoltaic performance to the platinum-based counter electrode, potentially due to its high electrocatalytic activity and small nanoparticle size providing increased surface area and catalytic sites. A theoretical model based on electrical considerations was used to study the impact of physical parameters on DSSC performance and efficiency, with the model accurately reproducing DSSC characteristics.

Summary: In this study, it is demonstrated that PtSe2 films, prepared by soft selenization of pre-deposited Pt, are highly efficient counter electrodes (CEs) in dye sensitized solar cells (DSSCs). Devices based on PtSe2 achieve better photoconversion efficiency (9.5±1.2%) compared to those using bare Pt CE (9.18±0.21%), even with lower Pt loading. The improved performance of PtSe2 CEs is attributed to the higher availability of catalytic active sites and more effective mechanism of interfacial electron transfer.
