A method is proposed for a thorough analysis of rear point contact solar cell structures. The method is based on the numerical solution through Fast fourier transform of the minority and majority carrier transport equations in three dimensions in the base of the cell. Their illuminated current-voltage characteristics are simulated and the series resistance of the cell is calculated. Results are presented which show the influence of the rear contact size and the majority transport in the base to the solar cell performance. © 2001 American Institute of Physics.

Rear point contact (locally diffused) solar cells with double collecting p/n junctions are investigated through numerical three-dimensional simulation and comparison with corresponding single junction solar cells. Their illuminated I–V characteristics are simulated and the series resistance of both structures is calculated. Results are presented which show the influence of the additional collecting junction to the cell''s series resistance and performance. It is also shown that by biasing both junctions under slightly different voltages, the efficiency of the cell slightly increases. [Copyright &y& Elsevier]
