2D MXene interface engineering for organic solar cells

Abstract

Organic solar cells (OSCs) have several advantages over conventional inorganic solar cells, including lower cost and greater flexibility. However, they also have some disadvantages that must be resolved to increase their performance and efficiency. Two-dimensional (2D) materials, known as MXenes, have recently attracted a lot of interest in organic chemistry. They are excellent candidates for various energy storage and conversion devices, including solar cells, due to their high surface area, good mechanical properties, and excellent electrical conductivity. The high conductivity of MXenes makes them perfect for use in a range of electronic devices, including photovoltaic (PV) technology. The transition metals and carbon atoms in MXenes, which can create a network of highly conductive pathways, give them high conductivity. The role of MXenes as an electron transport layer (ETL) and a hole transport layer (HTL) is highlighted in the review paper. It is strongly advised that MXenes be used in OSCs to achieve the highest performance levels. It has been shown that MXene, by utilizing its unique properties, can significantly increase the efficiency and stability of these devices. As a result, MXene is likely to keep competing fiercely to produce high-performance solar cells in the future. The review paper highlights MXene's growing potential and interest in energy materials, notably solar cells and other renewable energy technologies. MXenes may become more important as this field of study progresses, aiding in developing efficient and long-lasting energy solutions. Finally, the summary and prospects discuss current difficulties and future solutions.
