Abstract

Initial light induced degradation (ILID) has been observed in p-type single crystalline and multicrystalline solar cells. ILID is strongly correlated with high boron and oxygen content in the solar cell even though gallium-doped solar cells have experienced ILID. Recent theories suggest that n-type antimony-doped solar cells should be much less susceptible to ILID due to absence of boron. In addition, initial degradation of PV module of n-type solar cells has not been reported as of date. Using indoor solar simulation, PV modules containing n-type antimony-doped dendritic web silicon solar cells were studied for the presence of ILID. 1-V curve measurements were • made as the modules received their first light exposure. No degradation in V oc was observed, but a small amount of degradation up to 2% did appear in 15c and P max· The mechanism behind this very low level of degradation was unclear.
