Scientists in the United States theorize that a 'double absorber' cell comprising two active thin-film layers within one cell stack could achieve impressive efficiencies, whilst eliminating many of the challenges inherent to the design of tandem cells. For now though, it's only on paper.Tandem cells have been a hot topic among PV researchers for several years now, and are regarded by many as 'the future of solar cell technology'. But we are still yet to see commercial devices comprising this technology, and while perovskite-silicon is in the lead, there is a range of different device structures ...Den vollständigen Artikel lesen ...
