Because the triple junction does not exist on the Cu (In, Ga) Se2 solar cell surface, it should be free of electrostatic discharge. Electrostatic discharge tests on Cu (In, Ga) Se2 were performed in a vacuum chamber which simulated the plasma environment in low Earth orbit and the high-energy electron environment in geostationary orbit. Contrary to the theoretical expectations, electrostatic discharge occurred on the surface of Cu (In, Ga) Se2 and Cu (In, Ga) Se2 suffered degradation of electric performance. The arc track was investigated to make clear the degradation mechanism of Cu (In, Ga) Se2. The arc track worked as a leak resistance because the PN junction collapsed and the materials of front and back surfaces electroded adhere along the arc track.}, pages = {999--1006}, title = {Electrostatic Discharge Test on Cu (In, Ga) Se2 Solar Cell Array}, volume = {46}, year = {2009}, yomi = {トヨダ, カズヒロ and チヨウ, メンウ} }
