Quantifying the Energy Losses in CsPbI2Br Perovskite Solar Cells with an Open-Circuit Voltage of up to 1.45 V

Jingjing Tian, +10 more
- 24 Oct 2022 - 
TL;DR: In this paper , the authors demonstrate that adding lead acetate to the CsPbI2Br precursor allows to substantially reduce losses due to nonradiative recombination, and further analyze the strategies to reduce the residual losses in order to push the efficiency beyond the 90% theoretical limit.
Journal ArticleDOI

Er3+: emission from organic complexes embedded in thin polymer films

Markus Koppe, +7 more
- 15 Mar 2001 - 
TL;DR: In this article, the luminescence spectroscopy of Er 3+ complexes with 2,2'-Bipyridine, 1,10-Phenantroline, 2-dithienyl-2,2-bipyridazine ligands, embedded in thin films of poly(methylmethacrylate) (PMMA) as well as in films of a conjugated polymer, poly[2-methoxy, 5-(3',7' -dimethyl-octyloxy)]-p-phenylene vinylene (
Journal ArticleDOI

Journal ArticleDOI

Analytical model for light modulating impedance spectroscopy (LIMIS) in all-solid-state p-n junction solar cells at open-circuit

Osbel Almora, +5 more
- 02 Jan 2020 - 
TL;DR: In this article, a photoimpedance signal named "light intensity modulated impedance spectroscopy" (LIMIS = IMVS/IMPS) is analyzed, and its difference with respect to IS suggests a correlation with the surface charge carrier recombination velocity.
Journal ArticleDOI

Traps and transport resistance are the next frontiers for stable non-fullerene acceptor solar cells

Christopher Wöpke, +19 more
- 22 Mar 2022 - 
TL;DR: In this paper , degradation mechanisms of inverted photovoltaic devices were investigated and two distinct degradation pathways were identified: one requires the presence of both illumination and oxygen and features a short-circuit current reduction, the other one is induced thermally and marked by severe losses of open-circuits voltage and fill factor.
