KJLC is Supporting RhySearch in Switzerland with Vacuum Equipment

Mai 25, 2022 | Verfasser: KJLC Blog

Rhysearch

We are proud to have supported our customer RhySearch in Switzerland with equipment for their Ion Beam Sputtering of 2D Materials project.For this project, we supported RhySearch with the design and manufacturing of the complete vacuum system. The core of the project is the UHV vacuum chamber, which was manufactured and delivered by the Kurt J. Lesker Company. We also supplied most of the relevant equipment around the vacuum chamber, including motion manipulation parts, vacuum pumps, gauges, feedthroughs and valves.

In Situ Recrystallization of Co-Evaporated Cu(In,Ga)Se2 Thin Films by Copper Chloride Vapor Treatment towards Solar Cell Applications

Januar 17, 2022 | Verfasser: KJLC Innovate

The Kurt J Lesker Company has been providing Physical Vapor Deposition (PVD) systems to support photovoltaics (PV) research for more than 20 years and continues to support scientists globally to advance this critical renewable energy application. Bei Solarzellen werden Materialien verwendet, die Photonen aus Sonnenlicht in einem weiten Spektralbereich absorbieren und dieses eingefangene Licht effektiv in freie Ladungen umwandeln, die Strom erzeugen. Modern commercial solar cells are mainly based on crystalline Silicon, which is a cheap and abundant semiconductor[1]. In recent decades, alternative thin film technologies based on materials combinations including Copper indium gallium diselenide (Cu(In,Ga)Se2 or CIGS), Cadmium Telluride (CdTe), amorphous silicon and organic photovoltaics (OPV) have emerged with high efficiencies coupled with good cell stability, low manufacturing costs and come with the advantage of being a thin film, being both lightweight and flexible[2].

The Role of Spin in the Degradation of Organic Photovoltaics

Dezember 1, 2021 | Verfasser: KJLC Innovate

Organic electronics research has advanced rapidly over the past few decades, with organic light-emitting diodes (OLEDs) now being commonly available in commercial devices such as mobile phones and TVs. Organic photovoltaics (OPVs, or organic solar cells) have potential to follow OLEDs as a commercially viable technology, but a number of challenges still need to be overcome. A recent publication from an international collaboration, with lead authors Prof. Moritz Riede (University of Oxford) and Dr. Ivan Ramirez (Heliatek GmbH), has investigated the degradation pathways of OPV devices using a common organic material, C60, generating understanding which may prove critical to achieve long-term device stability. The complete solar cell structures used in the study were produced using a Kurt J. Lesker SPECTROS evaporation system.

Backstreaming of Pump Oil Vapors in Vacuum Systems - Detection, Quantification & Mitigation

Oktober 13, 2021 | Verfasser: KJLC Innovate

Systems evacuated with oil-based pumps may be victims of backstreaming of pump oil vapors into the fore- line, vacuum chamber, and upstream throughout the system. The back- streaming referred to here is the act of pump oil vapors moving against the flow of molecules traveling from the vacuum chamber to the pump(s). In this case, we refer to these oil vapors as moving upstream, and eventually into the vacuum chamber. At high pressures, where the number of molecules from the chamber outnumber pump oil vapor molecules emanating from the pumping system, flow upstream is greatly mitigated. Oil vapor back- streaming is significantly more pronounced at lower operating pressures.

Enhancing the Surface Properties & Functionalization of Polymethyl Methacrylate with Atomic Layer Deposited Titanium (IV) Oxide

Juni 7, 2021 | Verfasser: KJLC Innovate

Mina Shahmohammadi from the research group of Professor Christos G. Takoudis, Full Professor in the Departments of Bioengineering and Chemical Engineering at the University of Illinois at Chicago, in collaboration with College of Dentistry, University of Illinois at Chicago, and Kurt J. Lesker Company recently developed conformal atomic layer deposition (ALD) based titanium (IV) oxide (TiO2) thin film processes on Polymethyl Methacrylate (PMMA) displaying excellent surface and mechanical properties for potential engineering, medical, and biomedical applications. The findings were recently published in the Journal of Materials Science.

Determination of the Acoustic Impedance Ratio for the Thermal Co-evaporation of Metal-halide Perovskites

April 19, 2021 | Verfasser: KJLC Innovate

The Kurt J Lesker Company has been shipping Physical Vapor Deposition (PVD) tools into the field of perovskite solar cells for the last decade and continues to support researchers in this exciting application. Our partner, Dr. Sascha J. Wolter, along with the Future Technologies Photovoltaics group, headed by Dr. Sarah Kajari-Schröder, at the Institute for Solar Energy Research (ISFH) in Hamelin, Germany, have presented a method to determine the acoustic impedance ratio (Z) for two perovskite precursors that are commonly co-deposited using PVD. In their paper "Determination and influence evaluation of the acoustic impedance ratio for thermal evaporation"[1] they report Z values for methylammonium iodide (MAI) of 0,025 ±0,002 and 0,11 ±0,01 for lead (II) iodide (PbI2). Furthermore, the impact of using an incorrect Z-ratio on actual experimental thermal evaporations is investigated.
