The Photovoltaic Market Facing the Challenge of Organic Solar Cells: Economic and Technical Perspectives

Solar cells are gaining more interest in recent times as a possible technological solution to improve energy production whilst reducing its environmental impact. The majority of the market is still dominated by first generation solar cells made of single crystal or poly-crystalline silicon solar cells. Silicon technology has reached an high standard efficiency. However, silicon technology needs a very pure material that means high cost in dollar per watt. In order to improve the production of solar power, governments have started big economical interventions, like the feed-in tariff. The advancement of technology, especially the nano-technological revolution, is bringing the attention to another generation of solar cells, hybrid/organic solar cells like Dye Solar Cells, which reduce the costs and suggest the possibility of a mass production of solar modules without the need of public funds.
