WEBBED DENDRITIC SILICON SOLAR CELL RADIATION EFFECTS INVESTIGATION.
Abstract
An investigation was conducted to determine the optimum structure for silicon solar cells, with regard to resistance to damage by 2 MeV electrons. The parameters considered were cell type, i.e. P/N or N/P, junction depth, and base resistivity. Of all the parameters affecting cell radiation resistance, the initial efficiency was found to have the largest effect. A comparison was made to assess the superiorty of the optimum N/P structure, for 2 MeV electron flux densities in the range 10 to the 13th 10 to the 15th power electros/sq cm. The degradation rate per decade of flux for the P/N structure was about 25% vs 21% for the N/P cells. (Author)
