Energy requirements are increasing day by day and efforts are being made to combat the use of fossil fuels for raising energy needs. The use of renewable energy sources has gained a boost in recent years. Photovoltaics technology is being employed to extract energy from the sun. Photovoltaic technology captures sunlight and converts it into electrical energy. It plays a key role in harnessing renewable solar power for various applications. The conventional solar cell technology is associated with problems of high production cost and efficiency. Third generation solar cells are gaining popularity due to their low manufacturing cost, flexibility, and potential to increase efficiency. Perovskite solar cells (PSCs) have been studied a lot and efforts are being made to improve their efficiency from 25.7% as reported in 2021 as they have the potential to overcome the Shockey Queisser limit. They are seen as a promising alternative to traditional solar technologies. MXenes have a unique two-dimensional layered structure, composed of transition metal carbides, nitrides, or carbonitrides. MXenes offer excellent electrical conductivity, high carrier mobility, and tunable work function, making them ideal for use in PSCs as additives in the absorber layer, as well as in ETLs, HTLs, and electrodes. Integrating MXenes into perovskite solar cells enhances conductivity and charge transport, improving overall device efficiency. The following study explores the use of MXenes in perovskite solar cells and their effect on the efficiency of PSCs.
