Summary

Story summary

Researchers at the University of California, Los Angeles (UCLA) have developed a contact-induced charge-transfer doping method that reduces the energy barrier at the metal-perovskite interface from 250 nanometers to less than 25 nanometers.
The reduced barrier allows electrons to pass via quantum tunneling, boosting efficiency and lowering power consumption.
The technique uses silver oxide nanoclusters and could accelerate practical perovskite devices in solar cells and sensors, advancing integration into everyday electronics.
