✦ Synopsis
The unique properties of the diamond!like carbon "a]DLC#\ such as high mech! anical hardness and abrasive resistance\ optical transparency in the visible and IR spectral regions and high thermal conductivity\ provide this material with advantages over other types of protecting materials for solar cells[ Furthermore\ the a]DLC _lms are inert to corrosive gases and other corrosive agents[ Resistance to radiation damage of the a]DLC _lms deposited on solar cells is very important for space application[ In the study we investigate the effect of electron damage on silicon solar cells coated with a]DLC _lms[ We measure the IÐV characteristic and the spectral response and calculate the values of the seven parameters of the double exponential solar cell model "usually not investigated# as a function of electron ~uence irradiation[ In addition we obtain also the usual external parameters I sc \ V oc \ I m \ V m \ FF\ and ef_ciency# of the solar cells[ We investigate solar cells with and without anti!re~ecting coating coated with a]DLC _lms which were exposed to electron radiation[ The main _ndings show that the solar cells with a]DLC _lms of thickness up to 499 nm degrade similarly to regular silicon cells exposed to electron irradiation[ The degradation of the spectral response of the solar cell is mainly in the range of longer wavelengths and the irradiation affects the solar cell parameters "mainly the reverse saturation currents#[
