A major global issue that the world is facing today is the upcoming depletion of fossil fuels and the energy crisis. In 1998, the global annual energy consumption was 12. 7 TW; of which 80% was generated from fossil fuels. This also translates into huge annual emissions of CO that leads to massive environmental problems, 2 particularly the global warming, which could be disastrous. Future global annual energy needs are also estimated to rise dramatically. A major challenge confronting the world is to ?nd an additional 14-20 TW by 2050 when our energy reserves based on fossil fuels are vanishing. The massive demand for energy would require materials and/or processes that would help to provide new sources of clean ren- able energy or to develop processes that would harvest energy or to better utilize energy in an ef?cient manner. The present monograph, WOLEDs and Organic Photovoltaics - Recent Advances and Applications, focuses on a very important and timely subject of topical interest that deals with the more ef?cient use of energy through white organic light-emitting diodes (WOLEDs) for solid-state lighting and the development of clean sources of renewable energy through the harvesting of light energy for conversion into electrical energy in organic photovoltaics. While LED solid-state lighting and photovoltaics have been dominated by inorganic semiconductor materials and silicon-based solar cells, there have been growing interests in the development of WOLEDs and organic photovoltaics.
