Advanced Measurement solutions for maximum yield and efficiency
In the last years the overflow of global competitors and a fast-growing global production capacity has led to a dramatically decrease of system prices and put pressure especially on solar cell and module producers. Hence it becomes more and more important to convince customers by a high-quality standard and to further reduce prices. Furthermore, new technologies as TopCon or even Silicon-Perovskite tandem solar cells arise with new challenges for metrology and characterization.
Freiberg Instruments metrology solutions are ideal to help increasing the yield and the quality of the produced solar cells as well as characterizing new materials and processes. With them the material quality can be assessed right at the beginning of the production chain and be measured after every production step, from the ingot to the finished solar cell.

Key Advantages
High measurement speed and sensitivity
unsurpassed sensitivity due to our advanced microwave detection system, possibility to measure thin films or solar cells as well as wafers and ingots with a high measurement speed
High Accuracy and reproducibility
repeatability of below 1% for lifetime measurements and below 3% for resistivity measurements
Improvement of material yield
Determine the exact cutting criteria for top and bottom of an ingot, incoming inspection of wafers in 1 s
Versatile tools for ingots, wafers and even thin films
We offer tools for all kinds of different sample geometries from large ingots (up to 850 mm length) to thin films (1 µm thickness and less)
Inline metrology for wafers and ingots
Lifetime measurements are already a standard method for material quality control in the photovoltaic industry. Taking it one step further, our inline metrology tools allow to sort out low quality parts of the ingot, at as-grown wafers and after every process step.
Investigation of surface and bulk quality
The separation of bulk and surface quality is one of the main challenges of lifetime measurements. Freiberg Instruments offers a variety of different wavelength with different penetration depth and pulse length as well as estimations for bulk lifetime and surface recombination velocity.
