The dream of transforming windows into active power generators has just edged one step closer to realization.

A team of researchers from ARC Centre of Excellence in Exciton Science led by Professor Jacek Jasieniak from Monash University’s Department of Materials Science and Engineering has created perovskite cells with a conversion efficiency of 15.

The same team has since developed new cell formulations that combine caesium and formamidinium as parts of the initial perovskite composition, leading to efficiencies of 15.5 percent and 4.1 percent, with average visible transmittance of 20.7 percent and 52.4 percent, respectively, according to Don't be fooled by the reduced power conversion rates compared to previous results: the amount of visible light passing through the cells makes up for it.

“This work provides a major step forward towards realizing high efficiency and stable perovskite devices that can be deployed as solar windows to fulfill what is a largely untapped market opportunity,”The semi-transparent caesium and formamidinium perovskite solar cells also displayed exceptional long-term stability when tested under constant illumination and heating.
