Characterization of p+nn+ silicon concentrator solar cells

PDF Version Also Available for Download.

Description

The conversion efficiency, temperature coefficients of performance parameters, and the linearity of the short circuit current with irradiance are reported for silicon p+nn+ concentrator solar cells of 0.3 ..cap omega..-cm base resistivity. Conversion efficiencies of 20 percent at 27/sup 0/C were measured on the best cells over concentrations from 20 to 100 suns. A value of 0.26 percent//sup 0/C was determined for the normalized temperature coefficient of efficiency for irradiance levels at which the efficiency was maximum. The deviation from linearity of the short circuit current with irradiance was measured and found to be slightly superlinear in the multihundred-sun concentration ... continued below

The deviation from linearity of the short circuit current with irradiance was measured and found to be slightly superlinear in the multihundred-sun concentration range. Performance of cells with 1.0 and 10 ..cap omega..-cm base resistivities were also measured, and experimental and theoretical comparisons are made between the three cell types.
