Optical And Electrical Characterisation Of P3HT:PCBM Organic Photovoltaic Devices

BACKGROUND

The numerous limitations of inorganic solar cells has led to keen interest and exploitation of organic solar cells in recent times. They offer several advantages such as lightness, mechanical flexibility, low production cost, ease of processing and have a high potential for large area solar conversion1 . The properties, performance and lifespan of these solar cells depend on the properties of the active layer and interface between the components1 . Thus far research efforts have been focused on flexibility, colour for building integration, transparency and tackling some of the challenges limiting the industrial applications of organic solar cells22 especially their low efficiencies.
