Abstract

Solar Photo Voltaic (PV) cell is a device which directly converts solar energy into electrical energy by means of photovoltaic effects. Photovoltaic cells are made of semi conductors which generate electricity when they absorb light. PV cells generate electricity by using the renewable energy technology which generates green power. The Photovoltaic industry in India is facing severe shortage of silicon, hence the Government of India is not able to achieve the set targets. The purpose of this research paper is three fold: 1. To bring out the latest innovations to better the performance of PV modules. 2. Reduction of direct manufacturing cost. 3. Improve the conversion efficiency. This paper bases its premise on mono crystalline silicon (mono Si), poly crystalline silicon (poly Si) and edge defined film fed which growth silicon (EFG-Si). It brings out the fact that economies of large scale production and effective raw material management hold the key to cost reduction of PV Cells and by the application of these silicon technologies we get very high efficient PV cells.
