EVA Evaluation PIDcon allows producers to test both solar cells and encapsulation materials, with a focus on EVA foil’s impact on PID susceptibility The PIDcon allows for the investigation of how EVA foil affects PID susceptibility using a sample stack that simulates a module. To perform the test, the user simply places a solar cell, the EVA foil to be tested, and a glass layer on top. For accurate comparison, solar cells from the same batch and the same type of glass should be used. As shown in Figure 1, a noticeable difference in PID susceptibility is observed between the two EVA foils. EVA 1 demonstrates significantly better performance for modules than EVA 2.

Theoretical simulations will be performed to help to better understand the physical principles of the measurement principle. PERLE – Perovskite Tandem Solar Cells: Metrology for the PV Industry 2024/05/01 – 2027/04/30 In this project new methods for the inline characterization of Tandem solar cells based on MDP and SPS measurements are developed. Freiberg Instruments is working together with several research institutes and companies in this project to strengthen the German photovoltaic industry. Different layers and stacks of Perovskite and silicon are investigated and characterized. TemCrysT – GaN-Templates, GaN-Crystals and GaN-Wafers for the Development of GaN-Transistors 2023/07/01 – 2026/03/06 The aim of this project is to an automated characterization method for process control of GaN based on Raman measurements. This project aims to secure and expand the competitiveness of the semiconductor location Freiberg. For this purpose, Freiberg Instruments will develop a demonstrator for a fully automated confocal Raman measurement. This is used to analyze residual stresses, which naturally occur in the crystals due to the hetero-epitaxy process used. In this way, excellent feedback should be achieved along the entire process chain. In addition, the MDP method (microwave-detected photoconductivity), which has been established for silicon up to now, is to be applied to large HVPE GaN crystals for the first time and the possibilities of defect analysis on this material are to be researched and demonstrated. Furthermore, the capabilities of the newly developed SPV spectrometer (surface photovoltage) are to be adapted to GaN so that this device can be used for material characterization. G12 – Silicon mono-wafer development from M2 to G12: Cell geometries of the future 2022/04/01 – 2025/03/31 Development of the MDP lifetime measurement technology for monocrystalline bricks with a format of up to 210 x 210 mm The main goal of the "G12" project is the process and technology development of ingots and wafers with large format (formats (182x182 mm, 210x210 mm, possibly even 240x240 mm). The production of large ingots and large wafers requires further development of the crystallization systems, the process control, the mechanical processing of the ingot and bricks and ultimately also the qualification tools for the manufactured bricks and wafers. The focus of the sub-project at Freiberg Instruments is on the further development of lifetime measurements using MDP technology for large brick formats.

The focus of Freiberg Instruments is on further development of their inline lifetime measurement abilities using MDP for HJT and TOPcon technology. The main tasks are: System optimization for TopCon and HJT (inline - MDPlinescan , offline - MDPmap ) Identification of suitable excitation conditions in different manufacturing stages (TOPCon / HJT) Detectability of defects in selected process stages Development of a concept for an optimized MDPlinescan system SPV – Development of a surface photovoltage spectrometer for the characterization of photoactive materials 2021/01/01 – 2022/12/30 So far, there are no universally applicable compact SPV spectrometers (SPV: surface photovoltage) available on the market with which practically any photoactive materials and semiconductors can be examined. The aim of this project is to develop a compact SPV spectrometer. With the help of our innovative SPV spectrometer and the measurement set-up for which a patent has been applied, charge separation, electronic transitions and diffusion lengths should be characterized contactless and with unprecedented sensitivity over a very broad spectral range from deep UV to near infrared. In accordance with the complementary strengths of the project partners, the focus of Freiberg Instruments is on device development and production of the demonstrator, of HZB on method development, development of critical components, validation and tests, and HZG on simulation and development of analysis and simulation software for SPV.
