Prof. Steve Albrecht said, “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 and the HySPRINT Innovation lab teams have worked together successfully and with passion.”Prof Albrecht’s team used an advanced perovskite composition with a very smart interface modification. The lead authors, postdocs Dr. Silvia Mariotti, and Dr.
With the new certified value of 32.5%, the record is again back at HZB. “We are very excited about the new value as it shows that the perovskite/silicon tandem technology is highly promising for contributing to a sustainable energy supply,” said Prof Albrecht.HZB’s scientific director, Prof. Bernd Rech, emphasized: “At 32.5 percent, the solar cell efficiency of the HZB tandems is now in ranges previously only achieved by expensive III/V semiconductors.
What may be more important is the suggestion that this technology isn’t as expensive as top of the line silicon models in the III/IV range. In the lab for now, and costs not mentioned one does wonder ifThere is an installed solar industry that has aging cells not much over half the efficiency of this research. Worthwhile motive exists for progress.
Perovskite-based cells are not really mass-market ready for now, but this news could likely incite a bit more zip into “getting the lead out”, the basic recycling issue perovskite research is working to solve.More Top Reads From Oilprice.com:
