Poly-silicon (P-Si)

Metallurgical grade poly-silicon is the primary material of wafers used to fabricate crystalline silicon (c-Si) solar cells. It alone can account for 15-20% of the cost of a PV module. Currently India has minimal P-Si manufacturing capacity because of which Indian cell manufacturers are largely dependent on international tie-up for P-Si. This has been the most supply constrained element of the value chain globally and can have a cascading effect on the eventual cost of generation. This is the
