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.

SALSA - Measurement technology and sensitivity analysis for charge carrier selective solar cells

2021/04/01 – 2024/03/31

In the "SALSA" project, the inline measurement technology required for quality assurance and process control as well as quality assurance concepts are to be developed, optimized and techno-economically evaluated especially for progressive solar cell technologies such as the heterojunction route and the TOPCon route. 
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:
(1) System optimization for TopCon and HJT (inline - MDPlinescan, offline - MDPmap)
(2) Identification of suitable excitation conditions in different manufacturing stages (TOPCon / HJT)
(3) Detectability of defects in selected process stages
(4) Development of a concept for an optimized MDPline scan 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.

Technology transfer PIDcon bifacial

2020/07/01 – 2020/12/31

In this project, the novel technology for testing bifacial solar cells for their sensitivity to potential-induced degradation (PID) is to be transferred from the Fraunhofer Center for Silicon Photovoltaics CSP to Freiberg Instruments GmbH and adapted into a marketable product. The Fraunhofer CSP has applied for a patent for a novel process (process and arrangement for testing solar modules or solar cells for potential-induced degradation) and will transfer this knowledge to Freiberg Instruments.

This project is funded by SAB and the EU.
