This report describes the development of CIGS2 thin-film solar cells on glass and stainless-steel foil substrates; fabrication of a large-area, dual-chamber magnetron-sputtering unit; Round Robin AES and SIMS analysis; and current-voltage characteristics of CdTe modules and analysis of CdTe module samples. More detailed results on CIGS2 cells and the large-area, dual-chamber magnetron-sputtering unit were presented at the MRS Conference, the European PV Conference, and NCPV Program Review Meeting and are included in Appendices I, II, and III. The results of Round Robin AES and SIMS analysis were submitted to the National CIGS Team Meeting. The current-voltage characteristics of CdTe modules and results of analyses of CdTe module samples were submitted separately to NREL and First Solar. |
