Journal ArticleDOI
Enhancement of silicon solar cell efficiency by upconversion: Optical and electrical characterization
Stefan Fischer,Jan Christoph Goldschmidt,Philipp Löper,G. H. Bauer,R. Brüggemann,Karl Krämer,Daniel Biner,Martin Hermle,Stefan W. Glunz +8 more
TL;DR: In this article, the optical UC efficiency of trivalent erbium doped sodium yttrium fluoride (NaYF4:20%Er3+ +) was investigated for silicon solar cells.
Journal ArticleDOI
UV Degradation and Recovery of Perovskite Solar Cells
Sang Won Lee,Seongtak Kim,Soohyun Bae,Kyung-Jin Cho,Taewon Chung,Laura E. Mundt,Seunghun Lee,Seunghun Lee,Sungeun Park,Sungeun Park,Hyomin Park,Martin C. Schubert,Stefan W. Glunz,Stefan W. Glunz,Yohan Ko,Yongseok Jun,Yoonmook Kang,Hae-Seok Lee,Donghwan Kim +18 more
TL;DR: The degradation of perovskite solar cells in the presence of UV light alone was examined, and during exposure to consecutive UV light, the diminished short circuit current density (Jsc) and EQE continuously restored.
Journal ArticleDOI

Journal ArticleDOI
Increasing the efficiency of fluorescent concentrator systems
Jan Christoph Goldschmidt,Marius Peters,Armin Bösch,Henning Helmers,Frank Dimroth,Stefan W. Glunz,Gerhard Willeke +6 more
TL;DR: In this paper, a photonic structure that serves as a bandstop reflection filter for light emitted from dyes in the fluorescent concentrator increases the system efficiency relatively by 20%, such photonic structures are especially beneficial for larger systems.
