R.; Craig, J. D.; 2000; 10p; In English; Bioenergy 2000 Conference, Buffalo, NY., October 17, 2000 Report No.(s): PB2001-101544; No Copyright; Avail: National Technical Information Service (NTIS) Cratech, Inc. is processing with a three-phase effort to develop a small-scale biomass-fueled power plant. The biomass power plant concept envisioned is an air-blown pressurized fluidized-bed gasifier followed by a dry hot gas cleanup system with the resulting clean hot gas injected into the combustion chamber of a gas-turbine engine. This paper reports the latest efforts to complete development of Phase 2. Phase 2 is the design and construction of an upgraded gasification system based on the Phase 1 results. It is capable of providing pressurized hot clean gas for fueling a gas-turbine engine. Phase 3 is the modification of a gas-turbine engine to operate on the fuel produced by the Phase 2 system. A small gas-turbine generator package has been procured and will provide for economical fuel system and combustor modification, and subsequent testing.

The Second Quarter, 2000, issue is titled ’Our Shared PV Future’. It contains a review of several important PV-related meetings held in the prior three months: the NCPV Program Review, the 16 European PV Conference, and year-2000 Earth Day activities in Denver, CO. The editorialist is Paul Maycock, Publisher of PV News.

The second portion of this project focused on CIGS solar cells. The main tasks include the development of a manufacturable process for CIGS devices and the development of high-band-gap alloys for use in tandem cell structures. Additional objectives include development of improved junction formation processing and con- 194
tributing to the overall understanding of these materials and devices. Because the processing is manufacturing-driven, the authors use an all solid-state, simplified two-step process that relaxes the level of deposition control required.

Modules based on all these thin films are promising candidates to meet DOE long-range efficiency, reliability, and manufacturing cost goals. The critical issues being addressed under this program are intended to provide the science and engineering basis for the development of viable commercial processes and to improve module performance. The generic research issues addressed are: (1) quantitative analysis of processing steps to provide information for efficient commercial-scale equipment design and operation; (2) device characterization relating the device performance to materials properties and process conditions; (3) development of alloy materials with different bandgaps to allow improved device structures for stability and compatibility with module design; (4) development of improved window/heterojunction layers and contacts to improve device performance and reliability; and (5) evaluation of cell stability with respect to illumination, temperature, and ambient and with respect to device structure and module encapsulation.

This document reports on results from the second phase of a three-phase effort. Progress is reported on the development of new procedures and equipment for in-line wet chemical processes, sheet fabrication, solar cell processing, and module assembly. Future concepts and goals for the Silicon-Film process are also discussed. A major technical goal of this effort is the elimination of batch production processes in AstroPower’s solar cell process. New processes are being developed that can accommodate large-area Silicon-Film planks in an in-line, continuous manner. During Phase II of this program, an in-line chemical etching system for removing diffusion oxides was specified, procured, and installed. Operation of this system during Phase III of this program is expected to validate the in-line approach and will provide valuable information for use in the design of a second, and more challenging, in-line etch system. Significant progress was made during this reporting period in the development of new screenprinting ink formulations for both the front and back metallization of Silicon-Film solar cells. Cost reductions and efficiency improvements were achieved as a result of these efforts. Progress was made in the design of a new Silicon-Film plank machine, as well as in improved processes to fabricate this material into cost-effective and efficient solar cells. Additionally, a new large-area module concept was developed and prototyped during this phase of the PVMaT program.
