The PV1300 furnace is a directional solidification furnace ideal for G8 silicon ingot crystallization up to 1500 kg offered by ECM Greentech. It is adapted to mass production requirements. The design of our 3 heaters hot zone and innovative cooling device makes this furnace the most advanced DS furnace on the market. PV1300 furnace design has been developed for Crystalmax® cast-mono technology to grow fully <100> oriented G8 ingots up to 1500kg and gives the capacity to produce high ingot quality suitable to process high efficiency solar cells like PERC and Passivated Contacts technologies. It features optimised production cost due to high silicon feedstock yield, fully automatic thermal cycle, low maintenance cost and low electrical consumption and low carbon footprint. PV1300 furnace design is suitable with large size wafers production from M2 to M6 and M12 wafers.
