Abstract :
Simulations using optical interference effect on CuPC-C60 based organic solar cell devices are studied with the inclusion of a blend layer between the CuPC and C60 layers for enhanced exciton dissociation. The devices are found to show strong interference effects. Spectral and spatial dependence of optical power dissipated inside the device are critically reviewed. Total optical power dissipated for various thickness of the CuPC and blend layer are reported. Optimized thickness for CuPC and blend layers are found to enhance the total optical power dissipated inside the active layers. Short circuit current density in the devices are calculated using exciton diffusion to the interfaces. High absorption in CuPC and high exciton dissociation in blend are balanced to find the optimal thickness as 40 A and 380 A for CuPC and the blend respectively.
