CRI report – As the raw material for two industries, polysilicon is on the one hand applied in the preparation for polysilicon wafer in the semiconductor industry which is used as the substrate of semi-conductor silicon chip, thus silicon materials must meet strict requirements of purity and adulteration specifications; on the other hand, it can be applied in the production of solar cell panel in the photovoltaic (PV) field by purchasing non-specific materials eliminated in the semiconductor industry.
Although the PV cell occupies a very small part of the power field in the world, its importance should not be overlooked. Polysilicon and monocrystalline silicon dominate the market. The monocrystalline processed with the scraps of silicon bulk can meet the requirements of solar cell which does not need ultra purity like that of silicon wafer used in the semiconductor device. At present, the consumption of the semiconductor industry is 2/3 of the polysilicon output, and the remaining 1/3 are applied in solar cells.
Addressing an election rally at Jehanabad in Bihar on Wednesday, Congress General Secretary, Shri Rahul Gandhi stressed that only Congress Party truly believes in the welfare of backwards, tribals and weaker sections of the society. He revisited the promise made by Congress during the 2004 Parliamentary elections and said that he had promised that any Congress led government shall be a government of the poor, of the weaker sections, of the minorities, of the tribals. And since 2004, UPA government had undertaken many mega programmes for the upliftment of all such people who have stayed marginalized from witnessing the fruits of economic and social growth, he said.
Congress belongs to the common man and Congress government is obliged for their progress and development of each and every nook and corner of the nation, he said. He further said that since the focal point of Congress’s idelology is to work towards nation building and taking the fruits of development to each and every Indian, the party had decided to go alone with its message and dedicated work in UP and Bihar, he added.
