Introduction Since industrial revolution by the end of nineteenth century the consumption of fossil fuels to drive the economy has grown exponentially causing three primary global problems depletion of fossil fuels environmental pollution and climate change Andreev and Grilikhes 1997 . The population has quadrupled and our energy demand went up by 16 times in the 20th century exhausting the fossil fuel supply at an alarming rate Bartlett 1986 Wesiz 2004 . By the end of 2035 about 739 quadrillion Btu of energy 1 Btu W-hr of energy would be required to sustain current lifestyle of billion people worldwide US energy information administration 2010 . The increasing oil and gas prices gives us enough region to shift from burning fossil fuels to using clean safe and environmentally friendly technologies to produce electricity from renewable energy sources such as solar wind geothermal tidal waves etc Kamat 2007 . Photovoltaic PV technologies which convert solar energy directly into electricity are playing an ever increasing role in electricity production worldwide. Solar radiation strikes the earth with KWm-2 of solar irradiance which amounts to about 120 000 TW of power Kamat 2007 . Total global energy needs could thus be met if we cover of the earth s surface with solar cell module with an area 1 m2 producing 1KWh per day Messenger and Ventre 2004 . There are several primary competing PV technologies which includes a crystalline c-Si b thin film a-Si CdTe CIGS c organic and d concentrators in the market. Conventional crystalline silicon solar cells also called first generation solar cells with efficiency in the range of 15 - 21 holds about 85 of share of the PV market Carabe and Gandia
