Organic Solar Technique using P3HT and PCBM as Promising Materials

The Solar cells have the ability to meet some of these power demands by directly converting sunlight into electricity and can potentially generate power anywhere there is light. Organic solar cells represent of organic semiconductors have attracted considerable attention in the areas of electronics and photonics during the last decade. The conversion of sunlight to electricity by organic solar cells is very interesting and promising since organic solar cells offer the possibility of fabricating large area, flexible, light-weight, cost-effective devices using simple and environmental friendly techniques. Compared with inorganic solar cell, organic photovoltaic cell are less in cost, considering that organic solar cells can be fabricated onto the substrate by high-throughput, low cost fabrication methods. As a clean renewable energy source organic solar cells are rapidly developing. Power conversion efficiency over 7–8% was reported recently. On the other hand, there is a considerable progress in the evolution of organic solar cells from pure scientific research to a possible industrial application. Recent efforts are devoted to the investigation of operating mechanisms, new synthesis routes, new device architectures, stability of the organic materials, lifetime, encapsulation, etc.
