The solar PV industry is going through a revolutionized phase of wide scale application and price affordability under renewable energy thrive across the globe.

The Directional Solidification (DSS) Furnace for Silicon growth designed and built to international standards as a unique ‘Make in India’ initiative by Bangalore based Hind High Vacuum (HHV) is based on its expertise in industrial furnace manufacturing and long experience in manufacturing and supplying vacuum furnaces.

DSS furnace made by HHV is specifically designed for the PV industry and has the capability to produce high quality ingots suitable for processing high efficiency poly-crystalline solar cells.

The unique production mechanism can enhance the properties of the standard and mono-like/quasi-mono cells produced out of the wafers wire-sawed from these ingots to increase the performance of the solar cells further.

Said Nagarjun Sakhamuri, Managing Director, HHV, “The furnace is meant for the production as well as R&D on polycrystalline silicon ingot. This product is suitable for all the poly-C-Si solar cell manufacturers that want a backward integration in their PV production value chain and want to begin their own ingot/wafer production facility. Simultaneously, the existing ingot makers can make use of this latest equipment for improving the growth process and quality of ingots. The poly c-Si cell manufacturing industry, academia having R&D set up on improving production technology, not only from India but other parts of the globe also who does want to stay away from Chinese products will be able to get the benefits of having this system available from India.”

This furnace produces poly crystalline silicon ingots which undergoes minimum loss while producing wafers from it. This higher yield also contributes to the lowering of cost of solar wafer and cell.
