THE STUDY OF ORGANIC SOLAR CELL

Abstract

As the evidence for global warming continues to build, it is becoming clear that we will have to find non-CO2-releasing ways to create, transport, and store electricity. The whole of the World is engaged in finding a solution for energy crisis being faced by it. Among the alternatives, converting solar energy into electricity appears to be more promising as Environmental Impact Assessment of renewable energy technologies revealed that in long term it will help in reducing the damage of our environment and it is much cleaner than anyone else. Photovoltaic (PVs) technology is being increasingly recognized as one of the most important renewable energy technology. Diminishing fossil fuel resources and steadily increasing costs of their supply, and the detrimental long-term effects of CO2 and other emissions into our atmosphere underscore the multiple benefits of developing renewable energy resources and commercializing them for common man usage, particularly PVs. It is evident from the fact that worldwide photovoltaic (PV) industry reaches a cell/module production of 1200MWp in 2004, exhibiting an average annual growth of 40% over last 5 years. Besides, Japan, China, USA, EU countries and Australia forecast that this trend is expected to last at least for next 30 years. A significant capacity of about 200 GWp is expected to be operational around the globe in 2020. This number is the equivalent of 200 state-of-the-art nuclear power plants.
