  • It has been found useful in the past to use the concept of `equivalent fluence` to compare the radiation response of different solar cell technologies. Results are usually given in terms of an equivalent 1 MeV electron or an equivalent 10 MeV proton fluence. To specify cell response in a complex space-radiation environment in terms of an equivalent fluence, it is necessary to measure damage coefficients for a number of representative electron and proton energies. However, at the last Photovoltaic Specialist Conference the authors showed that nonionizing energy loss (NIEL) could be used to correlate damage coefficients for protons, usingmore » measurements for GaAs as an example. This correlation means that damage coefficients for all proton energies except near threshold can be predicted from a measurement made at one particular energy. NIEL is the exact equivalent for displacement damage of linear energy transfer (LET) for ionization energy loss. The use of NIEL in this way leads naturally to the concept of 10 MeV equivalent proton fluence. The situation for electron damage is more complex, however. It is shown that the concept of `displacement damage dose` gives a more general way of unifying damage coefficients. It follows that 1 MeV electron equivalent fluence is a special case of a more general quantity for unifying electron damage coefficients which we call the `effective 1 MeV electron equivalent dose`.« less
  • The authors compare the effects of irradiation with various energies on the output characteristics of silicon solar cells by writing the particle fluence as a displacement damage dose. Using this method, the degradation to a given cell structure in any radiation environment can be estimated. In addition, the authors show that the evolution of cell parameters can be calculated quite accurately using PC-1D with consideration of only the combined effects of minority carrier lifetime reduction and carrier removal. As a result, the behavior of different cell structures can be estimated very quickly.
  • A study of neutron-induced displacement damage effects as a function of temperature is reported for [ital n]-channel, 2-[mu]m channel length, depletion mode junction-field-effect-transistor (JFETs) fabricated on 6H-silicon carbide (SiC). Very little effect on the electrical characteristics of the devices was observed for neutron fluences less than 10[sup 15] n/cm[sup 2] and the effect for fluences greater than 10[sup 15] n/cm[sup 2] became less significant with increasing temperature. The results offer promise for SiC devices to be used in applications which combine high-temperature and radiation environments, where Si and GaAs technologies are limited.
  • Analysis of monoenergetic proton test data reveals displacement damage degradation of charge transfer efficiency in state-of-the-art CCDs. New measurements, in combination with literature data, demonstrate good agreement between the energy dependencies of proton damage and the nonionizing energy loss (NIEL) for protons in Si. Massive shields being considered to preserve CCD performance in satellites are then analyzed using the transport code BRYNTRN which quantifies both primary and secondary particle production. Using NIEL to combine the cumulative effects of both protons and neutrons reaching the CCD, the authors compare Al and Ta shield approaches for both trapped and flare proton environments.more » In general, massive Ta shields have diminished benefit owing to damage from large secondary neutron fluxes. Finally, analysis with Shockley-Read-Hall theory illustrates the importance of CCD operating conditions and transfer efficiency measurement techniques in evaluating flight performance and comparing results between devices and laboratories.« less
