Unformatted text preview: The Sun Shines on Photovoltaics S O L A R E N E R G Y T E C H N O L O G I E S Presentation Goals b Gain a comprehensive understanding of current solar technologies. b Preview solar energy predictions. b Convince you to tip your hat to photovoltaics. Essential Facts b Worldwide energy demand exceeds 13 TW, expected b Avg. Insulation on Earth = 1.2e5 TW. exceeds 13 TW, expected to approach 30 TW by 2050. b Demand: 1 nuclear reactor per day for 35 years. Earth = 1.2e5 TW. Photovoltaics Defined Photovoltaics (PV) is a method of generating electrical power by generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Current goals for PV Technology b Increase efficiency: b Increase efficiency: doping. b Lower manufacturing costs.
