KAUST Solar Center engineers have developed a silicon/perovskite tandem solar cell with efficiency
The new figure is 0.7% more thanprevious record holder: cells with 32.5% efficiency from the Helmholtz Zentrum Berlin team, which was announced in December last year. Recently, these records are often updated - just two years earlier, efficiency has not yet overcome the 30 percent barrier .
The KAUST team did not specify what improvements exactlywere introduced into the solar cell to set a new record. But such incremental progress usually comes through minor changes in materials, manufacturing methods, construction and design.
