Visit us from 31 May to 2 June 2017 in Hall A2, Stand 330
Intersolar Europe in Munich is the world“s leading exhibition for the solar industry and its partners. The exhibition focuses on the areas of photovoltaics, energy storage systems, renewable heating technologies, as well as products and solutions for smart renewable energy. From 31 May to 2 June 2017, Rehm Thermal Systems will present an information stand in Hall A2, Stand 330. Our exhibition team looks forward to your visit!
In solar cell manufacturing, Rehm is offering its new Speedfire Firing System and RDS Solar Dryers for the typical metallisation of monocrystalline and multicrystalline solar cells. The flexible, modular system design allows a wide range of production layouts, while the low energy consumption and high throughput makes the equipment very versatile.
Speedfire – firing equipment for top-quality solar cells
The high quality of the Rehm Speedfire Firing System is particularly impressive. The system is capable of producing high-efficiency solar cells with minimum breakage rates, especially at high throughput rates of up to 5,300 wafers/hour. Many energy-saving improvements and a multitude of software tools help to optimise the production process. The system is equipped with adjustable, powerful IR radiators, which metallise the solar cells to ensure upmost process stability. Thanks to the new two-chamber system in the firing zone, temperature variations due to unequal loading of the two lanes are now a thing of the past. The system is available as a pure Speedfire Firing System or with integrated dryer.
LID tool – improving efficiency and quality
Monocrystalline solar cells that are manufactured using the Czochralski process, suffer considerable efficiency losses during the first hours of exposure to the sun. Since solar cells and modules are sold according to their performance, eliminating what“s known as light-induced-degradation (LID) holds tremendous economic potential. Rehm has develped and modified a process that prevents the LID effect. The regeneration of the solar cell is carried out with a laser tool at significantly higher temperatures than before and by using hydrogenated silicon nitride. The efficiency and quality of the solar cell is therefore significantly improved. This process ideally follows the firing step.
RDS Solar Dryers: Maximum performance for optimal processes
The production of solar cells requires a drying system that is perfectly adapted to the diverse combinations of wafers and pastes. Rehm“s RDS Solar Dryer dries a paste applied via screen printing onto silicon solar cells at temperatures of up to 300 °C, or in the RDS HTX version at temperatures of up to 450 °C. The system consists of a combination of multiple infrared and convection zones. As a result, the temperature profile can be flexible, but still set with pinpoint accuracy. The solar cell is then cooled down gently so that it can be processed immediately. The optional VOC Thermal Oxidizer for purifying the exhaust air is also available.
99.0 % less VOC – the Thermal Oxidizer makes it possible!
Rehm“s VOC Thermal Oxidizer offers one of the most effective residue management systems on the market. The organic compounds released from the pastes during the heating process (Volatile Organic Compounds – VOCs) are cracked and almost entirely converted into carbon dioxide and water. All available systems operate with a maximum separation of 99.9 % and thus comply with the legal standards of TA-Luft/Germany. Oxidizer systems with heat recovery, such as the available CFR (Counter Flow Reactor), are also particularly energy-efficient and environmentally friendly.
