And increase electronics enhanced complexity of silicon cells used in buildings and various devices as an additional component you specific tasks but what would happen if the solar cells made ​​of material other than silicon?Ask me He was told that the new solar cell reached by the scientists made ​​from organic materials and the advantage of being flexible, lightweight and much cheaper than conventional solar cells is "organic" because it consists mainly of carbon, however, the main obstacle to organic solar cells to their efficiency in converting light into electricity very much lower compared to silicon cells.

 
Electronic traps .. And other obstacles
Consisting solar cell conventional thin layer semiconductor"crystalline solid resistance medium between conductors metallic and insulating materials" squeezed between two electricians and when it falls light on the semiconductor raised electrons near enough to "take off" the same restrictions installed by leaving behind holes and works an electric field is equipped with bipolar Ali urged electrons which carry a negative charge and the gaps" that carry a positive charge "to move the parties interviewers from the solar cell and the process is relatively easy in the semiconductor inorganic, such as silicon, but in the case of organic materials, we find that the force electron linking the largest gap by about a hundred times. Furthermore, the organic material is often a "trap" such as highway barricades impede the movement of electrons.
In spite of the modest efficiency of organic solar cells but other characteristics such as flexibility, light weight, durability and low cost make it attractive to a large extent this in addition to the possibility of integration in other materials due to the flexible nature .. Starting from fabrics to plastics "plastics" to the materials used in building roofs.
