"Examine, live, and do what you love."Facility: The Doumon Lab in Steidle Building
The Doumon Lab (SEMDE) is home to a variety of equipment, including:
Gloveboxes-integrated Spin Coaters (Specialty Coating Systems)
We have an integrated T-joined 4-gloves glovebox (housing the thermal evaporator) and a 3-gloves glovebox (Organic glovebox) for complete device fabrication. In addition, there are two 3-gloves gloveboxes: Perovskite glovebox and Multipurpose glovebox.
Perkin Elmer Lamda 1050+ UV-Vis-NIR Spectrometer
The lab. has an internal UV/Vis/NIR spectrometer. The LAMBDA 1050+ 2D base instrument is a high-performance UV/Vis/NIR double beam, double monochromator, and ratio recording spectrometer. Its wavelengths range from 175 nm to 3300 nm requiring an N2 purge below 185 nm. Our set-up comes with two detector accessories: a standard detector and an integrating sphere detector.
Slot-Die Coater (Ossila)
The SEMDE lab houses two (2) Ossila Slot-Die Coaters: One in a glovebox and the other in the ambient. The Ossila Slot-Die Coater is a small piece of equipment compared to others on the market. Fully operational via the digital controls on the unit itself, it allows you to easily program multi-step processes, where different system parts can be controlled independently.
Drying Oven (IKA Oven 125 Control – Dry Glass)
There is also a drying oven. The IKA Oven 125 dry glass is a powerful cabinet for temperature regulation, drying, ageing, and heating. It is built for rapid heating and precise temperature regulation and to guarantee reproducible results in research and industrial laboratories for quality control or science. It has high-quality insulation and a huge interior of 125 l. It reduces odor emissions and operating costs and ensures excellent temperature uniformity.
UV-ozone Cleaner (Jelight)
SEMDE is home to Jelight UV-ozone cleaner model 30. It comes with an ozone Killer and lower sets, allowing for its use without the need for external exhaust.
EQE Set-up (QUANTX-300)
The QuantX-300 has a redesigned cornerstone 130B monochromator providing upgraded performance with nearly doubled scan speeds, cutting measurement times by half compared to old Newport systems. It allows for simultaneous measurement of EQE and the reflective losses to quantify IQE with a wavelength range from 325 to 1800nm and is suitable for measurement on any photovoltaic device.
Newport Solar Simulator (MKS) with Keithley Sourcemeters
The group houses the 94043A solar simulator, a 4-inch x 4-inch area ozone-free source illumination Sol3A Class AAA Solar Simulator with a 450 Watt-Xenon lamp, measurement stage, Keithley 2400, and Keithley 2450.
Litos-Lite with Wavelabs AAA Solar simulator (Fluxim AG)
Litos-Lite is a set-up/tool to perform parallel JV (24-channels) and stability measurements on next-generation solar cells, allowing individual MPP tracking of each device and for temperature variation up to 100/125 degrees Celsius.
Key Features: Parallel J-V, Stability tests (ISOS protocols), MPP tracking, and Solar Simulator / LEDs.
Paios (Fluxim AG)
Paios is a tool allowing a variety of electrical and optical characterizations of organic and hybrid photovoltaic and optoelectronic devices with a click.
Key Features: Transient photocurrent, Transient photovoltage, Dark/photo-CELIV, Charge extraction, impedance spectroscopy, etc.
Tektronix MSO54B 5-BW-350 with Arbitrary /Function Generator

QYB Quantum Yield Berlin GmbH (LuQY Pro.)
According to QYB, The LuQY Pro is the most versatile, powerful, and easy-to-use absolute luminescence analysis system on the market. Its innovative and highly integrated concept allows absolute photo- and electroluminescence measurements out of the (shoe)box. The system thereby has a unique focus on opto-electronic device optimization (LEDs, solar cells, etc.) and can precisely simulate various operating points.
MUSE Laser Scribing System
This fun tool brings ideas to life, from simple gift items to fun crafts through sample patterning, engraving, etc. Being a device lab., we do fabricate a lot of devices. Our MUSE helps reduce the manual labor of labeling samples to rapid throughput laser patterning. Plus, it is fun to calve some “Welcome”, “Congratulations”, and other wishes to new, old, and outgoing members and visitors.
Bruker FTIR (INVENIO-S FT-IR: Available at the Energy Institute)
Our profilometer, the Bruker DXTa, has automated collection capabilities with an unlimited number of locations and motorized 360-degree rotation. It can accommodate single sample multiple-point measurements and multiple samples multiple points measurements. In addition to the functionality needed to collect accurate step height and surface roughness measurements, the DXT-A extends stylus profiling beyond two dimensions (2D) into three-dimensional (3D) analysis with 3D Mapping functionality.
LED/Solar Cell Measurement System:
The Ossila LED Measurement System provides a low cost and complete solution for performing current-voltage-luminance (IVL or JVL) characterization of LEDs. The device holder has built-in light sensors to allow for illuminance, luminance, and white count measurements. To simplify device testing, the software will also calculate the current and power efficiency of your LED. Lifetime mode, meanwhile, measures the performance of the LED over an extended time under a constant voltage (From Ossila website).
Four Point Probe:
The Four-Point Probe is an easy-to-use tool for the rapid measurement of sheet resistance, resistivity, and conductivity of materials. This four-point probe reduces the risk of damaging your delicate samples, such as polymer films with thicknesses on the order of nanometres. The probe head uses rounded, spring-loaded contacts instead of sharp needles for good electrical contact without piercing the sample.
Furnace:
Ideal for general laboratory use, including gravimetric analysis, sintering, quantitative analysis and heat treating.
Spin-coater (Specialty Coating Systems, SCS) : Multi-Dispense System in ambient and glovebox integrated
The SCS Multi-Dispense enables you to dispense liquid materials to an SCS Spin Coater from up to four different dispense modules (three with the use of N2). Materials can include coatings, solvents and cleaning solutions, in addition to the N2, which can be used for blow-off or drying. By including the SCS Multi-Dispense system, users can eliminate the need for time-consuming cleaning and change-over, while providing the accurate and controlled coatings capabilities backed by SCS and our years of coatings expertise (From SCS website).

The minimum size of thin glass that can be cut is less than 2mm. The typical lifetime of the cutting wheel is 20,000 meters for glass (From MSE website).
Contact Angle Goniometer:
The Ossila Contact Angle Goniometer provides a fast, reliable, and easy method to measure contact angles and surface tensions of liquid droplets. Our systems lets you achieve easier ink optimization with intuitive PC software, high quality video, and rapid image capture. Our software helps you characterize high contact angles for water resistant or protective coatings, or low contact angles for highly uniform solution coatings (From Ossila website).
