Laboratory Facilities

If you are interested in conducting research in the Aydin Group and would like to learn more about our laboratory infrastructure, this page provides an overview of our facilities.

Our laboratories support the full fabrication of perovskite single-junction, perovskite–silicon tandem, and all-perovskite tandem solar cells with high throughput and different scales. We operate multiple gloveboxes dedicated to specific processing steps, enabling several researchers to carry out experiments simultaneously. Thin-film deposition capabilities include two thermal evaporators equipped with multiple effusion sources and resistive boats, two sputtering systems with complementary functionalities (including soft-deposition options), and an atomic layer deposition (ALD) system for metal oxides. Substrate preparation is supported by plasma and UV–ozone cleaning systems, as well as multiple fume hoods for ambient-air processing and chemical synthesis. In addition, we have full access to a fully equipped wet-chemistry laboratory within our division.

For device characterization, our facilities enable current–voltage and stability measurements using LED solar simulators, covering full industrial device sizes and both terrestrial (AM1.5G) and space-relevant (AM0) spectra, as well as external quantum efficiency (EQE) measurements. We also have access to advanced optoelectronic characterization laboratories, including spectroscopic ellipsometry, UV–Vis-NIR (with integrated sphere) spectroscopy, steady-state and time-resolved photoluminescence (PL, TrPL), TCSPC, and Hall-effect measurements, as well as an impedance analyzer. Through collaboration with the Laquai Group, we further access streak-camera TRPL, photoinduced absorption (PIA), TDCF, and highly sensitive EQE systems.

Researchers in the Aydin Group have comprehensive access to structural, surface, and chemical characterization tools, including XRD; GIWAXS/GISAXS/WAXS/SAXS; SEM; TEM; FIB; AFM; FTIR; contact-angle measurements; DLS; and NMR (solid and liquid). XPS and UPS analyses are available through close collaboration with the Physics Department (CeNS facility). The group also has long-standing expertise in thin-film mechanical characterization, supported by sensitive universal testing systems and dedicated accessories.

In addition, we are actively developing customized stability and aging platforms, including MPPT systems, space-simulation setups, and programmable vibration system, to perform state-of-the-art terrestrial and space-relevant reliability testing. Rapid prototyping is supported by in-house 3D printing, and the department provides access to mechanical workshops with CNC machining as well as electronics workshops. The building infrastructure includes centralized supplies of pressurized nitrogen and dry air for gloveboxes and reaction chambers.

Overall, our facilities support comprehensive synthesis, structural, chemical, photophysical, and device-level characterization, enabling end-to-end research on advanced photovoltaic materials and devices.
