Photovoltaic Manufacturing Technology (PVMaT) Improvements for ENTECH's Concentrator Module, Final Technical Report, 9 January 1991 - 14 April 1991

This final technical report documents ENTECH's Phase I contract under the Photovoltaic Manufacturing Technology (PVMaT) project. Under this project we prepared a detailed description of our current manufacturing process for making our unique linear Fresnel lens photovoltaic concentrator modules. In addition, we prepared a detailed description of an improved manufacturing process, which willsimultaneously increase module production rates, enhance module quality, and substantially reduce module costs. We also identified potential problems in implementing the new manufacturing process, and we proposed solutions to these anticipated problems. Before discussing the key results of our program, however, we present a brief description of our unique photovoltaic technology. The keyconclusion of our PVMaT Phase I study is that our module technology, without further breakthroughs, can realistically meet the near-term DOE goal of 12 cents/kWh levelized electricity cost, provided that we successfully implement the new manufacturing process at a production volume of at least 10 megawatts per year. The key recommendation from our Phase 1 study is to continue our PVMaT projectinto Phase 2A, which is directed toward the actual manufacturing technology development required for our new module production process.
