Abstract

A CPV module containing 30 III-V multijunction cells was operated on-sun for one year in Golden, Colorado. Each cell was characterized prior to and following exposure. A module power degradation of 10 % was observed and found to be a result as an overall decrease in cell short circuit current and the presence of at least one shunted cell. A positive correlation between initial shunt current and an increase in shunt current following exposure was also found. Cell exfoliation was also observed and found to be coincident with the presence of water and/or charring of the cell package due to an off-sun event.
