THE EFFECT OF 4 MEV ELECTRONS ON COVERED BRITISH SILICON SOLAR CELLS.
Abstract
An experimental study has been made of the effects of 4 MeV electron bombardment on the spectral response and orbital performance of two British makes of 10 ohm cm n/p silicon solar cells with cemented-on 0.006-in. glass cover slips. A subsidiary purpose of the study was to compare the latest measurement techniques employing short circuit current calibrations in the laboratory with those in Malta sunlight. The two methods were found to give results in close agreement. A factor relating the mean Malta calibration to the air mass zero short-circuit current was established and found to be remarkably insensitive to shifts in spectral response of the cells. The results of the study are presented as a series of mean spectral response and voltagecurrent curves showing the effect of various radiation fluxes. The performance parameters of interest are also plotted as a function of electron flux. The probable fall in solar cell output during the life of the UK.3 satellite is predicted from the data.
