Mixed self-assembled monolayer enables 18.88% efficiency in 5.2 cm² inverted perovskite solar cell

Researchers at the Indian Institute of Technology Bombay have fabricated a large-area inverted perovskite solar cell based on a mixed self-assembled monolayer (SAM) that improves perovskite film quality, enhances charge transport, reduces interfacial recombination losses, and increases device efficiency and stability. SAMs have emerged as key components in high-efficiency perovskite solar cells, particularly in inverted architectures, where they serve as ultrathin hole-selective contacts that improve charge extraction and reduce interfacial recombination losses. Previous research has shown that ...
