Book Advanced Processing of CdTe and CuInxGa sub 1 x Se2 Based Solar Cells Phase I Report

Download or read book Advanced Processing of CdTe and CuInxGa sub 1 x Se2 Based Solar Cells Phase I Report written by and published by . This book was released on 2000 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main tasks of the cadmium telluride portion of this project include the development of simplified processing for fabricating high-efficiency CdTe solar cells, studies on the long-term stability of CdTe devices, and the development of alternative transparent conducting oxides, window layers, and back contacts. 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 contributing 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.

Book Advanced Processing of CdTe and CuIn 1 x Ga X Se2 Based Solar Cells

Download or read book Advanced Processing of CdTe and CuIn 1 x Ga X Se2 Based Solar Cells written by Don Louis Morel and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project addresses most of the key CdTe technology areas, with focus on improving the manufacturability and long-term stability of this technology. The activities over this 3-year period include developing simplified processing, studying novel front and back contacts, and improving long-term stability. This report describes work carried out during the last year of the project. The solar cells discussed below are fabricated by various deposition technologies that include chemical vapor deposition, chemical-bath deposition, close-spaced sublimation, and rf-sputtering. The devices are routinely evaluated using standard solar cell analytical techniques such as dark and light current-voltage, spectral response, and capacitance-voltage measurements.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes work performed by the University of South Florida Department of Electrical Engineering under this subcontract. The Cadmium telluride(CdTe) portion of this project deals with the development of high-efficiency thin-filmed CdTe solar cells using fabrication techniques that are suitable for manufacturing environments.

Book Advanced Processing of CdTe and CuIn subscript X Ga subscript 1 x Se2 Based Solar Cells

Download or read book Advanced Processing of CdTe and CuIn subscript X Ga subscript 1 x Se2 Based Solar Cells written by Don Louis Morel and published by . This book was released on 1997 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this project is to develop high-efficiency CdTe solar cells based on processing conditions favorable for manufacturing processes. This report presents the results on work performed during the first phase of this project. One of the major issues addressed is the use of soda-lime glass substrates in place of the borosilicate glass often used for laboratory devices; another task is the preparation of Cu(In,Ga) Se2 solar cells by selenizing suitable precursor films. Emphasis is placed on processing and how different reaction schemes affect device performance. It was found that different reaction schemes not only change the bulk properties of Cu(In,Ga)Se2, but also its surface properties, which critically affect device performance. Although the objective is to optimize processing to meet the manufacturing constraints, work has not been limited within these requirements.

Book Processing and Modeling Issues for Thin film Solar Cell Devices Final Report

Download or read book Processing and Modeling Issues for Thin film Solar Cell Devices Final Report written by and published by . This book was released on 1997 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the third phase of the subcontract, IEC researchers have continued to provide the thin film PV community with greater depth of understanding and insight into a wide variety of issues including: the deposition and characterization of CuIn{sub 1-x}GaxSe2, a-Si, CdTe, CdS, and TCO thin films; the relationships between film and device properties; and the processing and analysis of thin film PV devices. This has been achieved through the systematic investigation of all aspects of film and device production and through the analysis and quantification of the reaction chemistries involved in thin film deposition. This methodology has led to controlled fabrications of 15% efficient CuIn{sub 1-x}GaxSe2 solar cells over a wide range of Ga compositions, improved process control of the fabrication of 10% efficient a-Si solar cells, and reliable and generally applicable procedures for both contacting and doping films. Additional accomplishments are listed below.

Book Development of Advanced CdTe Solar Cells Based on High Temperature Corning Glass Substrates Cooperative Research and Development Final Report CRADA Number CRD 10 373

Download or read book Development of Advanced CdTe Solar Cells Based on High Temperature Corning Glass Substrates Cooperative Research and Development Final Report CRADA Number CRD 10 373 written by and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: NREL has developed advanced processes for CdTe solar cells, but because of the temperature limitations of conventional soda lime glass, many of these processes have not been transferred to manufacturing. Corning is developing high temperature substrate glasses that are believed to be manufacturable and will lead to lower $/watt modules costs. The purpose of this CRADA is to evaluate these glassesin the advanced NREL processes. In addition, the CRADA seeks to develop manufacturable processes for transparent conductive oxide layers based on cadmium stannate.
