The High Performance Photovoltaic Project held a Kickoff Meeting in October, 2001. This booklet contains the presentations given by subcontractors and in-house teams at that meeting. The areas of subcontracted research under the HiPer project include Polycrystalline Thin Films and Multijunction Concentrators. The in-house teams in this initiative will focus on three areas: 1.) High-Performance Thin-Film Team-leads the investigation of tandem structures and low-flux concentrators, 2.) High-Efficiency Concepts and Concentrators Team-an expansion of an existing team that leads the development of high-flux concentrators, and 3.) Thin-Film Process Integration Team-will perform fundamental process and characterization research, to resolve the complex issues of making thin-film multijunction devices.
