Exploration of the compositional space for mixed lead halogen perovskites for high efficiency solar cells
T. Jesper Jacobsson,Juan-Pablo Correa-Baena,Meysam Pazoki,Michael Saliba,Kurt Schenk,Michael Grätzel,Anders Hagfeldt,Anders Hagfeldt +7 more
TL;DR: In this article, the authors explored the perovskites in a compositional space and derived the absorption and the emission behavior as well as the crystallographic properties of the pervskites.
Journal ArticleDOI

TL;DR: An open-circuit voltage of over 1,000 mV is reported in mesoscopic dye-sensitized solar cells incorporating a molecularly engineered cobalt complex as redox mediator, indicating that the molecularly engineering cobalt redox shuttle is a legitimate alternative to the commonly used I3−/I− redox Shuttle.
Journal ArticleDOI
Counter electrodes for DSC: Application of functional materials as catalysts
TL;DR: In this article, a carbon-black-loaded stainless steel electrode was used as a counter electrode for dye-sensitized solar cells, achieving high photovoltaic performance.
Journal ArticleDOI

Steve Albrecht,Michael Saliba,Juan Pablo Correa Baena,Felix Lang,Lukas Kegelmann,Mathias Mews,Ludmilla Steier,Antonio Abate,Jörg Rappich,Lars Korte,Rutger Schlatmann,Mohammad Khaja Nazeeruddin,Anders Hagfeldt,Michael Grätzel,Bernd Rech +14 more
TL;DR: In this paper, an 18% efficient monolithic silicon/perovskite tandem solar cells were constructed by combining optical optimization of the device architecture including light trapping approaches. But the design of the tandem cell is limited by the photocurrent generated in the silicon bottom cell that is reduced due to reflectance losses.
