Effect of the irradiation temperature on the spectral response of Si solar cells

The authors describe the variation of the spectral response of LILT, Si solar cells especially designed for deep space missions irradiated with 10/sup 16/ cm/sup -2/, 1 MeV, electrons versus the temperature of irradiation in the range 80-300 K. Since the spectral response SR(/spl lambda/) is temperature dependent, the degradation is given in terms of the quantity 1-SR(/spl lambda/)/SR/sub 0/(/spl lambda/) where SR/sub 0/ is the spectral response of the unirradiated cell. These data are correlated with the changes induced by the irradiation in the short circuit current. Information on the main recombination centers introduced by the irradiation at various temperatures can then be extracted.
