Working Principle of Organic Polymer Solar Cells
The fundamental difference between the working principles of organic and inorganic solar cells is the direct generation of free charge carries in the inorganic solar cells. In organic materials the light absorption is followed by the creation of excitons with a typical binding energy (due to coulomb-interaction) of 0.3-0.5 eV.
