Low Dimensional Materials for Solar Cells and Electrochemical Sensing Applications

Abstract

The integration of low-dimensional nanomaterials has propelled significant advancements in both solar energy harvesting and electrochemical sensing technologies. This thesis focuses on exploring the unique properties of these materials, particularly their high surface area, tunable optical and electronic characteristics, and superior electrochemical performance. The work is divided into two main areas: solar cells and electrochemical sensing. In the field of solar energy, transition metal dichalcogenides (TMDs), especially molybdenum disulfide (MoS2), have been investigated as counter-electrode materials for quantum dot-sensitized solar cells (QDSSCs). The research demonstrates the superior electrocatalytic activity, stability, and efficiency of functionalized 1T-MoS2 compared to its 2H counterpart, underscoring its potential to enhance solar cell performance. newline
