This book was released on 1994 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work to develop an advanced, low-cost manufacturing process for a now utility-scale, flat-plate module. This process starts with the production of continuous sheets of thin-film, polycrystalline silicon using the Silicon-Film{trademark} process. Sheets are cut into wafers that are nominally 15 cm on a side. Fifty-six of these wafers are then fabricated into solar cells that are strung together into a 170-W module. Twelve of these modules form a 2-kW array. The program has three main components: (1) development of a Silicon-Film{trademark} wafer machine that is capable of manufacturing waters that are 225 cm2 in size at a rate of 3.0 MW/yr, with a total product cost reduction of 70%; (2) development of an advanced solar cell manufacturing process that is capable of turning the Silicon-Film{trademark} wafer into a 3.25-W solar cell; and (3) development of an advanced module design based on these large-area silicon solar cells with an average power of 170 W for 56 solar cells and 113 W for 36 solar cells.

This book was released on 1994 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: AstroPower is in the second phase of a 3-year, phased effort to upgrade its facility to produce 1.22-m2 Silicon-Film{trademark} PV modules with an output of 170 W{sub p}. Productivity improvements of the Silicon-Film{trademark} machine were accomplished during the second phase. Improvements were made in solar cell performance while decreasing materials consumption, integrating and mechanizing the fabrication process for solar cells, and scaling-up solar cell and module equipment for fabricating larger cells. AstroPower is continuing work on separating out effects due to impurities and effects due to defects. Analytical tools were developed for measuring area-based response based on EBIC and LBIC methods. The Kauffman source for hydrogen ion implantation was used to map out the process space for Silicon-Film{trademark} solar cell improvement. Progress was made on improving short-circuit current. Areas of focus include developing tools to quickly assess material quality; developing a hydrogen implantation process; increasing material quality on large-area, high-throughput wafers; and studying potential processes for improving solar cell power output during cell fabrication. A method to improve current collection in a solar cell after contact formation is under development.

This book was released on 1994 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to develop an advanced, low-cost manufacturing process for a new utility-scale, flat-plate module. The program has three main components: development of a Silicon-Film{trademark} (S-F) wafer machine that is capable of manufacturing wafers that are 225 cm2 in size with a total product cost reduction of 70%; development of an advanced solar cell manufacturing process that is capable of turning the wafer into a 14% efficient solar cell; and development of an advanced module design based on these large area, efficient silicon solar cells with an average power of 170 watts for 56 solar cells and 113 watts for 36 solar cells. During Phase 2, AstroPower made significant advances in improving S-F material quality and device performance. Advances were made in developing the prototype machines and processes toward reliable manufacturing counterparts. The following key achievements in Phase 2 are detailed: demonstration of a truly continuous production mode S-F machine; demonstration of a 2.5 watt, 15 cm by 15 cm solar cell; and demonstration of a 78 watt module fabricated from 36, 15 cm by 15 cm S-F solar cells.

This book was released on 1994 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work performed under a 3-year contract to demonstrate signfficant cost reductions and improvements in manufacturing technology. The work focused an near-term projects for implementation in the Siemens Solar Industries (SSI) Czochralski (CZ) manufacturing facility in Camarillo, California, and was undertaken to increase the commercial viability and volume of photovoltaic manufacturing by evaluating the most significant cost categories and then lowering the cost of each Rem through experimentation, materials refinement, and better industrial engineering. During this reporting period, several significant improvements were achieved. (1) The crystal-growing operation improved with an increase in growth capacity. Higher growing throughput was demonstrated with larger crucibles, higher polysilicon packing density, and higher pull speeds. (2) The operation was completely converted to wire-saw wafer processing. The wire saws yield over 40% more wafers per inch in production. The capacity improvement generated by wire saws increased overall manufacturing volume by more than 40% without additional expenses in cyrstal growth. (3) Cell processing improvements focused on better understanding of the contact paste and firing processes. (4) Module designs for lower material and labor costs began with the focus on a new junction box, larger modules with larger cells, and less costly framing technique. CFC usage was completely eliminated in the SSI manufacturing facility during this phase of the contract.
