MATLAB simulation of Mie scattering by hollow sphere TiO2 for dye solar cell application

The capability to capture photons by photoelectrode film of a Dye Solar Cell (DSC) can be improved through improvement of the light harvesting efficiency (LHE). Incorporation of light scattering center in the photoelectrode film has shown promising results in improving the LHE. The scattering center...
