The Photovoltaic Manufacturing Technology (PVMaT) Project was initiated in 1990 to help the U.S. photovoltaic (PV) industry extend its world leadership role in manufacturing and commercially developing PV modules and systems. It is being conducted in several phases, staggered to support industry progress. The four most recently awarded subcontracts (Phase 2B) are now completing their first year of research. They include two subcontracts in CdTe, one on Spheral Solarm Cells, and one on cast polysilicon. These subcontracts represent new technology additions to the PVMaT Project. Subcontracts initiated in earlier phases are nearing completion, and their progress is summarized. An additional phase of PVMaT, Phase 4A, is being initiated which will emphasize productdriven manufacturing research and development. The intention of Phase 4A is to emphasize improvement and cost reduction in the manufacture of full-system PV products. The work areas may include, but not limited to, issues such as improvement of module manufacturing processes; system and system component packaging, integration, manufacturing, and assembly; product manufacturing flexibility; and balance-of-system development with the goal of product manufacturing improvements .
The Photovoltaic Manufacturing Technology (FVMaT) project is a governmenthidustry photovoltaic manufacturing R&D project composed of partnerships between the federal government (through the U.S. Department of Energy) and members of the U.S. PV industry. It is designed to assist the U.S. PV industry in improving manufacturing processes, accelerating manufacturing cost reductions for PV modules, increasing commercial product performance, and generally laying the groundwork for a substantial scaleup of US.-based PV manufacturing plant capabilities.The project is being carried out in three separate phases, each focused on a specific approach to solving the problems identified by the industrial participants. These participants are selected through competitive procurements. Furthermore, the PVMaT project has been specifically structured to ensure that these PV manufacturing R&D subcontract awards are selected with no intention of either directing funding toward specific PV technologies (e.g., amorphous silicon, polycrystalline thin films,
The energy per ion pair for natural uranium alpha particles has been measured for several gases in a gridded parallel-plate ion chamber. Electron collection was used. The gases employed were He, Ne, A, Kr, N2, A-f 3 percent CO2, and A+5 percent N2. On a relative basis, the results are in good agreement with those obtained by Jesse and Sadauskis using heavy ion collection. The absolute values herein reported are about 6 percent higher than those resulting from slow chamber measurements.
This paper examines the goals of the Photovoltaic Manufacturing Technology (PVMaT) project and its achievements in recapturing the investment by the photovoltaic (PV) industry and the public in this research The PVMaT project was initiated in 1990 with the goal of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
