This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes work performed by Solar Cells, Inc. (SCI), during this Photovoltaic Manufacturing Technology (PVMaT) subcontract. Cadmium telluride (CdTe) is recognized as on of the leading materials for low-cost photovoltaic modules. SCI has developed this technology and is preparing to scale its pilot production capabilities to a multi-megawatt level. This four-phase PVMaT subcontractsupports these efforts. The work was related to product definition, process definition, equipment engineering, and support programs development. In the area of product definition and demonstration, two products were specified and demonstrated--a grid-connected, frameless, high-voltage product that incorporates a pigtail potting design and a remote low-voltage product that may be framed and mayincorporate a junction box. SCI produced a 60.3-W thin-film CdTe module with total-area efficiency of 8.4%; SCI also improved module pass rate on the interim qualification test protocol from less than 20% to 100% as a result of work related to the subcontract. In the manufacturing process definition area, the multi-megawatt manufacturing process was defined, several of the key processes weredemonstrated, and the process was redefined and proven on a 100-kW pilot line that now operates as a 250-kW line. In the area of multi-megawatt manufacturing-line conceptual design review, SCI completed a conceptual layout of the multi-megawatt lines. The layout models the manufacturing line and predicts manufacturing costs. SCI projected an optimized capacity, two-shift/day operation of greaterthan 25 MW at a manufacturing cost of below $1.00/W.

This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: First Solar is actively commercializing CdTe-based thin-film photovoltaics. During the past year, major additions of production capability have been completed, as well as process improvements to achieve higher throughput and efficiency and greater durability. This report presents the results of Phase II of the subcontract, entitled 'Research Leading to High Throughput Manufacturing of Thin-FilmCdTe PV Modules.' The subcontract supports several important aspects needed for high-volume manufacturing of high-efficiency modules, including exploration of large-area advanced front-contact window layers, improvements of the semiconductor deposition system, advancement in understanding of post-deposition processing steps and accelerated life testing methods, and progress in the environmental,health and safety programs. Work under this subcontract contributes to the overall manufacturing operation. During Phase II, average module efficiency (total area) on the production line was improved from 7.9% to 8.6% due primarily to process optimization. At the same, time production volume for commercial sales increased from 2.5 MW in 2003 to an estimated 6 MW in 2004. Much of the new 25 MW/yrproduction line has been qualified, and production volume is steadily increasing.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the significant progress made in four areas of this subcontract: process and equipment development; efficiency improvement; characterization and analysis; and environmental, health, and safety. As part of the process and equipment development effort, vapor-transport deposition (VTD) was implemented first on a 60-cm-web pilot-production system, then on a 120-cm-web high-throughput coater. Deposition of CdS and CdTe films at a throughput of 3 m2/min was demonstrated, and more than 56,000 plates (each 0.72 m2) were coated -- 16 times the total number coated prior to the start of the contract. Progress was also made in the conversion efficiency and yield of both standard and next-generation modules, with data from more than 3000 sequentially deposited modules having an average total-area conversion efficiency of 7% and next-generation modules produced with efficiency as high as 9.3% (10.15% aperture-area efficiency as measured by NREL). Successful implementation o f in-situ CdS thickness measurements was important to progress in thickness uniformity and control. Net CdTe material utilization of 82% was demonstrated. The ability to raise the utilization further was shown with the demonstration of inherent CdS and CdTe material utilizations of over 90%. Post-CdTe-deposition process development, which included process space exploration and problem diagnosis, was an important part of advances in efficiency and yield. As part of the efficiency-improvement task, research was done on cells and modules with reduced CdS thickness to increase photocurrent.

Download or read book Research Leading to High Throughput Manufacturing of Thin-Film CdTe PV Modules written by R. C. Powell and published by . This book was released on 2006 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specific overall objectives of this subcontract are improvement in baseline field performance of manufactured CdTe PV modules while reducing environmental, health and safety risk in the manufacturing environment. Project objectives focus on four broad categories: (1) development of advanced front-contact window layers, (2) improved semiconductor film deposition, (3) development of improved accelerated life test procedures that indicate baseline field performance, and (4) reduction of cadmium-related environmental, health and safety risks. First Solar has significantly increased manufacturing capacity from less than 2 MW/yr to more than 20 MW/yr, while increasing the average module total-area power conversion efficiency from 7% to>9%. First Solar currently manufactures and sells 50-65-W thin-film CdTe PV modules at a rate of about 1.9 MW/month. Sales backlog (booked sales less current inventory divided by production rate) is more than a year. First Solar is currently building new facilities and installing additional equipment to increase production capacity by 50 MW/yr; the additional capacity is expected to come on line in the third quarter of 2006.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results and conclusions from Phase II of a three-year subcontract are presented. The subcontract, entitled 'Technology Support for High-Throughput Processing of Thin-Film CdTe PV Modules,' is First Solar's portion of the Thin-Film Photovoltaic Partnership Program. The research effort of this subcontract is divided into four areas of effort: 1) process and equipment development, 2) efficiencyimprovement, 3) characterization and analysis, and 4) environmental, health, and safety. As part of the process and equipment development effort, a new semiconductor deposition system with a throughput of 3 m2/min was completed, and a production line in a new 75,000 ft2 facility was started and is near completion. As part of the efficiency-improvement task, research was done on cells and moduleswith thin CdS and buffer layers as way to increase photocurrent with no loss in the other photovoltaic characteristics. A number of activities were part of the characterization and analysis task, including developing a new admittance spectroscopy system, with a range of 0.001 Hz to 100 kHz, to characterize cells. As part of the environmental, health, and safety task, the methanol-based CdCl2process was replaced with aqueous-CdCl2. This change enabled the retention of a 'De Minimus' level of emissions for the manufacturing plant, so no permitting is required.
