This report summarizes the work performed by Materials Research Group, Inc., in Phase 2 of this subcontract. Progress toward the development of in-situ sensors for CuIn(Ga)Se{sub 2} (CIGS) during Phase 2 includes: (1) design and assembly of a low-cost X-ray fluorescence (XRF) sensor suitable for in-situ use and real-time control; (2) demonstration of agreement between theory and experiment for XRF measurement simple systems using the XRF sensor; (3) demonstration of agreement between inductively coupled plasma (ICP) and XRF results over a wide variety of CIGS samples; (4) initial design of hardware protecting XRF sensor in heated, Se ambient; (5) resolution of a number of installation issues, including specification of measurement time versus sensor-to-sample distance, utilities requirements, and vibration restrictions; (6) development of software for sensor operation and the automatic extraction of composition data; and interaction with National CIS R and D Team industrial partners to specify and adapt sensor functions.
