perovskite solar cellssurface reactivityThe non-radiative recombination at the interfaces of perovskite solar cells (PSCs) is a crucial issue that limits the efficiency and stability of the devices. State-of-the-art surface passivation strategies usually utilize alkyl ammonium halides to suppress the ...
Halide perovskite materials have been extensively explored for their unique electrical, optical, magnetic, and catalytic properties. Most notably, solar cells based on perovskite thin films have improved their power conversion efficiency from 3.8% to ove

"We and several other groups found that simply introducing an extra amount of organic halides in the precursor can help to passivate the defects and achieve highly emissive perovskite films" says Zhongcheng Yuan, PhD student in Department of Physics, Chemistry and Biology (IFM) at LiU, who is ...
Perovskite solar cells (PSCs) are one of the emerging solar cell technologies with high conversion efficiency. Several deposition methods had been applied for preparing their hole transport layer (HTL). However, there are few direct evidences to demonstrate whether HTL and its interfaces in PSCs ...
Working with Pireta Ltd, CPI is using its industry expertise in the printed ... Researchers find more stable perovskite solar cells 15 Oct 2018 By exchanging the organic methylammonium (MA) with inorganic elements, the researchers have shown it is possible to avoid these unstable compounds while...
Figure 1.Structure types: (a) CaCI, (b) NaCl, (c) zinc blende; the general form of the structure is shown in the upper part of the figure, and the polyhedral representation in the lower part with this structure include almost all the alkali halides (LiF, LiCl,. . ., NaF, NaCl,....
Metal-halide perovskite solar cells have garnered significant research attention in the last decade due to their exceptional photovoltaic performance and potential for commercialization. Despite achieving remarkable power conversion efficiency of up t
The efficiency and stability of perovskite solar cells are essentially determined by defects in the perovskite layer, yet their chemical nature and linking with the degradation mechanism of devices remain unclear. Here we uncover where degradation occurs
