This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this program is to investigate the feasibility of using Cu/sub 2-x/Se as a semiconductor material for the low cost production of photovoltaic solar cells. Progress is reported. The Cu/sub 2-x/Se films are produced by coevaporation from individually monitored Cu and Se vapor sources. With a substrate temperature of 170°C, single phase cubic Cu/sub 2-x/Se films have been produced. These films have a direct band gap of 2.2 eV and an indirect band gap of 1.4 eV.

Book excerpt: The purpose of this program is to investigate the feasibility of using Cu/sub 2-x/Se as a semiconductor material for the low cost production of photovoltaic solar cells. The first quarter of the program (May 1, 1979 through August 1, 1979) is described. The emphasis to date has been to produce Cu/sub 2-x/Se films of good uniformity and reproducibility. The films are deposited onto glass substrates heated to approximately 200°C. The Cu and Se are evaporated from separate sources, each individually monitored for rate by quartz crystal microbalances. The techniques used are readily adaptable for scale up to large volume production. Preliminary measurements of optical absorption, electron diffraction, and Hall measurements have been made.

Fabrication of Cu/sub 2-x/Se/CdS cells has begun. Both front wall and back wall cells have been made. A theoretical computation on the thin-film Cu/sub 2-x/Se/CdS cell has indicated an achievable efficiency of greater than 10%.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research program was the investigation of copper selenide (Cu/sub 2-x/Se) films as a promising potential semiconductor material for low cost, mass produced thin film photovoltaic solar cells. Major activities during this program have been the development of the semiconductor film formation process, characterization of the deposited films, calculation of the projected cell performance from theoretical analysis, and the fabrication and testing of simple cell structures. Progress is reported.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Work to develop the theory controlling the electroplating of a compound semiconductor on a transparent, conductive substrate and to demonstrate operative solar cells using the approach is reported. The current program is divided essentially into three paralleled team efforts. The first effort centers on refining the electroplating process at Monosolar so thicker and more uniform layers of p- or n-type cadmium telluride can be plated on both In2O3:Sn- and Ni- coated substrates. 1 .mu.M thick polycrystalline films have been achieved for the first time ever without peeling problems, a thickness optimum for maximum solar absorption and economy of materials. Second, work is underway at UCLA to physically and electrically characterize the films and diodes made from them. Under proper conditions Schottky diodes with better than 104 rectification ratios at 1.5 V were obtained along with preliminary indications of grain sizes up to 1 .mu.M. Measurements of these diodes revealed the presence of deep trapping level(s) that may be associated with plating process impurities that since may have been eliminated. Third, work so far on developing improved techniques for depositing ITO has been successful at UCLA in their effort to eliminate persistent problems with ITO obtained from outside suppliers serving the less demanding liquid crystal display (LCD) industry.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress is reported on a program to develop an InP/CdS polycrystalline thin film solar cell. The plasma deposition system was completed and a number of depositions of InP were made with the indium transported into the reaction zone via the vapor phase transport of indium chloride. Amorphous film of InP were obtained when the substrate was at room temperature. Substrate temperatures above approximately 200°C resulted in polycrystalline films. Junctions were formed in n-type InP by diffusion of Cd using a sealed tube technique. (WHK).

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts this past quarter emphasized the assembly of a three source deposition system, studies of the chemical composition of the surface of Cu2O substrates, continued investigation of current mechanisms in Cu/Cu2O Schottky barriers, and fabrication and characterization of Cu/SiO2/Cu2O MIS cells. Time was also devoted to further calculations of expected photocurrent from Cu2O solar cells, and thermodynamic considerations concerning the stability of interfaces in possible Cu2O cell structures. Key accomplishments include: (1) measurement of optical absorption coefficient for Cu2O; (2) completion of MBE system; (3) preliminary identification of two current mechanisms operative in Cu/Cu2O cells.
