Figure 6

Simulated spatial distribution of the squared optical electric field |E|2 (normalized to the incoming plane wave) for different the devices (a) Device A and Device B for 500 nm, (b) Device C, Device D and Device E for 400 nm, 500 nm and 600 nm with the same y-axes scale. (The insert figures in brackets mean the relative area ratio in active layer. All the simulation were calculated via Matlab program, the Matlab files were provided from McGehee group, Center for Advanced Molecular Photovoltaics, Stanford University⁵³).
