Composite paste based on PbSe nanoparticles and carbon black thin film counter electrode for cadmium selenide quantum dot-sensitized solar cells |
초록 |
QDSSCs are designed based on the interfacial charge separation between a short band gap (donor) and a large band gap (acceptor) semiconductor. Polysulfide electrolyte and Pt counter electrode are the most commonly used in QDSSCs. However, the Pt-based counter electrode shows reduced activity in the polysulfide electrolyte due to poisoning effect. In this study, PbSe/Carbon Black (CB) composite electrode has been fabricated from pre-synthesized PbSe nanoparticles and Carbon Black with assist of PVDF as binder material by doctor-blading. Additionally, to enhance contact properties of composite film to FTO, post thermal treatment was done at Ar ambient. PbSe NPs/CB exhibited much higher catalytic property with polysulfide electrolyte than Pt. QDSSC with composite counter electrode achieved a power conversion efficiency 4.275% which is higher than Pt counter electrodes |
