Abstract

The built-in electrical potential of Cu(In, Ga)Se₂ (CIGS) solar cells was measured. The profiles of the electrical potential along cross sections of the device demonstrates that the p-n junction is a buried homojunction located in the CIGS film. The built-in electric fields had indicated that the cadmium sulfide and zinc oxide layers of the device structure were inactive for the collection of photoexcited carriers.
