PV20 : DSS furnace G1

DSS photovoltaic of G1 silicon ingot crystal growth

The PV20 furnace is a directional solidification furnace from ECM Lab Solutions. It is ideal for G1 silicon ingot crystallization, up to 20 kg, and adheres to directional solidification process engineering requirements at laboratory or pilot scale. The PV20 furnace is available with Crystalmax® cast-mono technology, and designed with a three-zone thermal set-up. This set-up enables high reliability, reproducibility, and flexibility in the process growth of silicon ingots. The furnace is user friendly and designed specifically for research and development.
