Rehm: New Thermal Systems for PV Production
Production ovens for processing photovoltaics.
Blauberen, Germany — Rehm Thermal Systems has introduced an advanced new series of drying systems and firing systems for solar cell metallization. These systems offer a range of advanced process features and thermal control that enable PV manufacturers to move their processes to an entirely new level of efficiency and yield.

The drying process consists of a combination of five IR zones and one central convection zone, offering temperature profiling that can be adjusted for both precision and flexibility. These horizontal throughput systems guarantee a safe transport through the oven using either mesh belt or with pin chain up to 3 lanes. In the mesh belt systems, the conveyor for the heating zone can be separated from that of the cooling zone. Consequently, no latent heat is carried into the cooling area which offers a higher cooling gradient and a shorter oven. At belt speeds up to 6m/minute, the RDS Series provides high throughputs of up to 5700 wph.

The new systems are also available with the company's Condensate Residue Management System, a process that controls the buildup of unwanted paste solvent and vehicle residue in the process chamber and extends the maintenance intervals. The entire process chamber of the RDS Series drying systems is designed to be readily accessible for maintenance purposes. The oven opens from the front and uses removable sheets that can be easily removed for cleaning, significantly reducing the maintenance time and effort.

Launched following exhaustive testing by the renowned Fraunhofer Institute ISE, the new Rehm RFS Fast Firing Furnace is designed for PV manufacturing. A complete lineup of thermal solutions for metallization now includes the RFS Firing System and RFS-D combination Drying and Firing System in addition to the model RDS series dryers. All units are designed for low energy consumption in a compact footprint that optimizes factory space while minimizing expense.

The new systems provide very high throughput rates — transport speeds up to 6m/minute and multiple lanes — to maximize productivity. Flexible transport systems enable single-, dual-, and triple-lane handling of wafers.

An Integrated residue management system maintains an exceptionally clean process chamber and extends maintenance intervals, and excellent profile control and process monitoring, includes reference products for baseline profiling.

The company's Visu2 software includes traceability tools, remote diagnostics and an extensive product library.
