EST, the Certifying Institute European Solar Test Installation based in Italy measured a new tandem cell. The value of about 32.5% of solar radiation converted into electrical energy was officially confirmed. The value is also part of the NREL solar cell technologies chart.
The United States National Renewable Energy Laboratory updates the chart.

Various research organizations and businesses have been working on improving efficiency over the past few years, and the last month in particular has been very exciting for the industry.
“At 32.5 percent, the solar cell efficiency of the HZB tandems is now in ranges previously only achieved by expensive III/V semiconductors. The NREL graph clearly shows how spectacular the last two increases from EPFL and HZB really are,” informs Prof. Bernd Rech, Scientific Director, HZB.

At 32.5%, this number is quite satisfying for a sustainable energy-oriented future.
In other words, the current record of tandem solar cells comprising silicon bottom cells besides aperovskite is again linked to HZB.
“This is a really big leap forward that we didn’t foresee a few months ago. All the teams involved at HZB, especially the PV Competence Center (PVComB) and the HySPRINT Innovation lab teams have worked together successfully and with passion,” says Prof. Steve Albrecht, HZB.
