  • Revolutionizing solar cell technology: Indian researchers develop high-efficiency 2D Dion-Jacobson perovskite cell with MXene materials, reducing recombination losses for optimal performance.

Researchers at India's Chitkara University Institute of Engineering and Technology have developed a 2D Dion-Jacobson perovskite solar cell with MXene materials, achieving remarkable efficiency and open-circuit voltage. The new cell architecture allows charge carriers to move smoothly through the layers, reducing recombination losses. MXenes, known for their unique optoelectronic properties, were used as contacts in the cell, along with bandgap grading techniques.

The team's comprehensive theoretical investigation combined MXene contacts with the 2D DJ perovskite layer, optimizing the composition and layer thickness. The device achieved a power conversion efficiency of 17.47%, an open-circuit voltage of 1.05 V, and promising results under different grading profiles, showcasing the potential of this novel approach in advancing 2D-perovskite solar cell technology.
