- Description
- The present study aims to utilize Mn, Ni, and MnNi Prussian Blue Analogue (PBA) embedded MoS2 composites as Pt-free Counter Electrode (CE) in Dye Sensitized Solar Cells (DSSCs). Therefore, Ni-PBA, Mn-PBA, and MnNi-PBA were synthesized using a simple ageing procedure followed by a Hydrothermal method to prepare modified MoS2 composites. The crystalline structure, shape, surface area, and elemental oxidation state were analyzed using various studies. Also, the nanosheets formation around cubic structure further shows large numbers of active sites resulting in the high catalytic behaviour of the composites. Among the various composites, the Modified MoS2 based on MnNi-PBA, which was coated using a simple spin-coating procedure, exhibited the smallest ?EPP separation and the highest JRED value due to the rapid redox reaction at the CE/electrolyte interface and catalytic current. The maximum efficiency of 8.25 % was achieved for MnNi-PBA based composites, surpassing pristine MoS2 (6.72 %) and Pt (7.58 %) under front illumination (100 mW/cm2). Under rear illumination, the cell demonstrated a higher efficiency of 4.96 %, attributed to the high transmittance of the material-coated CE, making it suitable for bifacial applications. 2024 International Solar Energy Society
