As the scale of the solar cell moves into nanometer regime, the numerical analysis should evolve at the same pace. By using the Matlab® as the tool and solving the general Poisson and continuity equations, we are able to have a good platform for the nano-scale solar cells. By adapting proper parameters, the perovskite solar cells and their behavior under different surface recombination conditions...
A numerical method to correlate the surface recombination velocity and the Fermi-level pinning is provided. This correlation was integrated into the simulation of the GaAs nano-scale solar cells, and the surface-dependent performance of the solar cells can be obtained. This method is also applied to the simulation of the radial-junction nanorod solar cells with sidewall contacts.
The charge collection probability is one of the most important parameters of a solar cell. We derived two kinds of special functions to fit the external quantum efficiency and use then to reconstruct the charge collection probability. The simulation results of gallium arsenide and silicon solar cells are put into comparison.
