Abstract
Molybdenum disulfide (MoS2), is a novel 2-D material, has recently garnered significant attention. In this study, MoS2 nanosheets (NSs) were synthesized via a liquid-phase exfoliation (LPE) method, and subsequently used to modify the titanium dioxide (TiO2) photoanode of dye-sensitized solar cells (DSSCs). The incorporation of MoS2 NSs not only enhances dye adsorption due to their high specific surface area but also reduces the carrier recombination rate attributed to their excellent carrier mobility. These combined effects contribute to an improvement in the photovoltaic conversion efficiency (PCE) of DSSCs. Notably, the efficiency of DSSCs with MoS2 modification increased from 4.99% to 6.55%, representing a 31% improvement.
期刊介绍:
IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
