The key to removing a solar cell from a completed solar panel is to remove the EVA that surrounds the solar cell without damaging or contaminating the solar cell itself. This system is designed specifically to extract solar cells by thermal decomposition of the surrounding EVA at the lowest possible temperatures to extract a clean, uncontaminated, and undamaged solar cell.
The core component is the EVA burning oven that is capable of handling a large sample up to 12”x12” while both dry air and water vapor can be used for decomposition of EVA. The chamber is specially designed to prevent iron and copper contamination during the high-temperature process that is problem for most conventional ovens and furnaces on the market for use with solar cells. The oven ensures complete removal of EVA below 500°C. Lower temperatures run lower risk of damaging or contaminating the solar cell.
An afterburner is included in the system (not pictured) to completely convert the exhaust from the oven into carbon dioxide. The exhaust from the afterburner connects directly to building exhaust.
This system features an optional water vaporizer (shown in picture). The water vapor allows steamed air for the oven. If you wish to attempt lower temperatures of the oven, this is an option to consider.
This system also has an optional preheating furnace (not pictured) for dry air. You can heat the air before it enters the oven up to 500°C, improving the temperature uniformity in the oven.
