Summary: Transition metal compound catalysts have potential applications in Pt-free counter electrodes (CEs) for reducing costs and improving power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs). In this study, CuWO4@C composite catalysts were synthesized by pyrolyzing Cu-based polyoxotungstate (H3PW12O40) precursor in the presence of polyaniline. The effects of pyrolysis temperature on the composition, morphology, and structure of the CuWO4@C composite were investigated. The optimal pyrolysis temperature of 800 degrees C resulted in the highest PCE of 7.11% for the regeneration of I3/I couple in the DSSCs.

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.

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: Vanadium-based nitrides have been widely used as platinum-free counter electrodes (CEs) electro-catalysts for dyesensitized solar cells (DSSCs) due to their low cost and easy doping and modification. In this study, polyoxovanadate (NH4)2V6O16 was used with melamine to prepare VN@C composites through five different synthesis routes. The catalytic performance of the VN@C composite CEs was evaluated and it was found that the composites prepared by the chemical mixing method exhibited higher performance in DSSCs due to improved conductivity and a high concentration of active sites.
