Summary: A promising and straightforward approach for efficient and inexpensive counter electrodes (CEs) in dye-sensitized solar cells (DSSCs) has been demonstrated using polyaniline (PANI) doped with poly (sodium 4-styrenesulphonate) (PSSNa). The doping of PSSNa improved the performance of PANI by enhancing electron transfer, suppressing charge recombination, and increasing effective surface area. The DSSCs with PANI-PSSNa CEs showed a 25.21% higher efficiency compared to those with PANI CEs.

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: 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: A few-layered MoS2 was successfully grown on nitrogen-doped carbon derived from zeolitic imidazolate framework (ZIF-8) via the hydrothermal method. The MoS2/NC-PEDOT: PSS composite showed promising catalytic ability and optical transparency, leading to excellent power conversion efficiency in bi-facial dye-sensitized solar cells (DSSCs). Its performance with both I-3 /I- and [Co(bpy)312+/3+ redox mediators is comparable to Pt-based devices, making it a promising Pt-free option for DSSCs.

Summary: Facile two-step hydrothermal and chemical vapor deposition approaches were developed for in situ growth of cobalt phosphide and vanadium phosphide on carbon paper. The resulting CoP/V2P/CP composite can be directly used as counter electrodes for dye-sensitized solar cells without post-treatment. The CoP/V2P/CP CE exhibited higher electrocatalytic activity and lower charge-transfer resistance than the Pt CE, leading to a higher power conversion efficiency (9.47% vs 7.43%) for the DSSC.
