World's Most Efficient Solar Cell with 47.6 Percent Efficiency

Researchers, using a new antireflection coating, have successfully increased the efficiency of the best four-junction solar cell to date from 46.1 to 47.6 percent at a concentration of 665 suns. This is a global milestone, as there is currently no solar cell with a higher efficiency worldwide.

World Record Solar Cell Goes From Lab to Industry

While the solar research community has witnessed even higher perovskite-tandem cell efficiencies, these records have been achieved using lab technology that is not directly transferrable into mass production. The achievement of Q CELLS and Helmholtz-Zentrum Berlin is noteworthy principally because the 28.7% efficiency was reached using an industry feasible and cost-efficient bottom cell structure.

Perovskite/Silicon Tandem Solar Cells on Threshold of 30% Efficiency

An HZB team has published a report in the journal Science on the development of its current world record of 29.15% efficiency for a tandem solar cell made of perovskite and silicon. The tandem cell provided stable performance for 300 hours - even without encapsulation. To accomplish this, the group headed by Prof. Steve Albrecht investigated physical processes at the interfaces to improve the transport of the charge carriers.

Record-breaking solar cells get ready for mass production

Sandwiching an oxygen-rich layer of silicon between a solar cell and its metal contact has allowed researchers in Europe to break performance records for the efficiency with which silicon solar cells convert sunlight into electricity. But the challenge now is how to make these so-called passivating contacts suitable for mass production.
