Overview

The R2R slot die printing machine is an industrial printing machine, which can produce organic and perovskite solar modules by slot die coating and laser processes on a flexible substrate with up to 2 m/min. This machine can be used for advanced prototyping of large-scale modules or high throughput material research.

Detailed Description

Purpose: Solar modules with industrial relevant processes and output can be produced in this infrastructure. The machine consists of three slot die stations, hot air an infrared ovens, web cleaning stations, a inline laser and bus bar lamination. All processes are optimized for a fast and reliable solar module production. Due to the usage of industry relevant processes and materials, perfect prototypes can be made.
In addition, the same processes can be used for material qualification and high throughput evaluation, including machine learning.
