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

Researchers in India developed an inverted perovskite solar cell based on a mixed self-assembled monolayer (SAM) that reportedly improves film quality, charge transport, and device stability. The cell achieved 18.88% efficiency on a 5.2 cm² active area, with a relative efficiency loss of only around 7% compared with smaller devices.
