Advancements in Perovskite Solar Cell Efficiency

This chapter explores the efficiency of perovskite solar cells, examining the advantages and limitations of multi-layer designs for spectrum absorption. It highlights current efficiency ceilings, the concept of diminishing returns with added layers, and compares perovskite cells with traditional silicon panels. The discussion includes future prospects for multi-junction solar cells and the significance of achieving a 30% efficiency threshold in commercial products within the next five to seven years.
