Improved optical and electrochemical performance of MoS2-incorporated TiO2-PbS nanocomposite for solar paint application

摘要: Solar paint-based quantum dot-sensitized solar cells are promising low-cost photovoltaic devices. However, due to various detrimental optoelectronic features including poor transfer and higher recombination of electrons holes (e–h), paints exhibit inferior performance. In this regard, we used exfoliated MoS2 in TiO2-PbS nanocomposite (NC)-based paint ensued its better charge carrier generation characteristics. At first, sheets were effectually developed via liquid-phase exfoliation technique from bulk powder then strategically incorporated NC. NC was synthesized using pseudo-successive ionic layer adsorption reaction (p-SILAR) method qualitatively analyzed SEM, EDS, UV–Vis spectroscopy, other techniques. Differential scanning calorimetry revealed the efficacy addition as it exhibited compatible thermal behavior with which is critical for application. Using impedance-based electrochemical spectroscopic investigation polysulfide electrolyte, concluded that successfully yields lower resistance dictates superior performance paint.
