An efficient platform based on strontium titanate nanocubes interleaved polypyrrole nanohybrid as counter electrode for dye-sensitized solar cell

摘要: Abstract In the present work, we have synthesized polypyrrole incorporated with SrTiO3 nanoparticles by oxidative polymerization method. The prepared samples were thoroughly characterized various instrumental methods for crystallinity and crystal structure, chemical bonding, optical nature, morphology, elemental composition, etc. X-ray diffraction (XRD) patterns showed highly crystalline nanoparticle. With addition of in PPy, a PPy-SrTiO3 nanocomposite was achieved. Moreover, this confirms formation evenly distributed nanoparticle-polymer interaction. FESEM images revealed that PPy exhibited nanosphere morphology. Further, nanocubes it shows high SrTiO3. mapping show details about distribution into polymeric chain PPy. EDX spectrum indicated presence C, Ti, O, Sr, N, Si nanocomposite. successful composites properties confirmed FTIR UV–Vis spectroscopic analysis. evolution electronic circuits optoelectronic devices, is crucially significant but remains challenging to fabricate new electrode switches traditional platinum (Pt) indium counter electrodes dye-sensitized solar cells (DSSCs). These conventionally used exhibit noticeable cons such as instability, cost, complex fabrication when DSSCs. Therefore, unaided DSSC very low efficiency 1.29%. However, incorporation poly matrix enhanced surface area, electrocatalytic response towards redox system, also charge transfer resistance. Among other concentrations, PPy-SrTiO3-50% achieved power conversion 2.52% which higher than sputtered Pt i.e. 2.17%.
