Improving perovskite solar cell performance with silver nanoparticles

Scientists in the United Kingdom have proposed for the first time to deposit silver nanoparticles in electron transport layers used in perovskite solar cells to improve device performance. They found that an “optimal” concentration of silver nanoparticles may help to improve a perovskite cell’s charge transfer and extraction, as well as its efficiency.

Inverted perovskite-organic tandem solar cell achieves 23.07% efficiency via metal ion-doped absorber

A group of scientists in Korea has a hot-air technique instead of atomic layer deposition to fabricate a perovskite absorber that reportedly shows a higher film quality. They applied this film in a perovskite-organic tandem solar cell, which exhibited low open-circuit voltage losses and high efficiency levels.
