Abstract

Starting materials for the preparation of thick film cadmium sulfide and cadmium telluride solar cells have been comminuted. Initial trial films of cadmium sulfide showed that during the next phase of this work, the printing of films, one of the major problem areas will be to obtain sufficient reflow in the printed films to remove the screen-caused variation in film thickness. The thin areas corresponding to the screen pattern caused pinholes to form in the fired parts.

Commercialization of a thick film solar cell. Quarterly technical progress report, January 1, 1980-March 31, 1980

Technical Report McDonald, G. D.

Initial problems encountered in the screen printing of CdS films related to an undesirable surface texture on the film surface have been resolved by modification of ink rheology. Improvements have been made in CdS films through modification in firing conditions, ink composition, and fluxing. The CdS 13 micron thick films are devoid of through pores and have a resistivity of 1.65 ohm cm. A laser probe technique was developed to determine macro variations in solar cell films.

Supported growth of polycrystalline silicon sheet on low-cost ceramic, carbon, or reusable substrate. Quarterly report No. 1, September 26-December 31, 1979

Technical Report Chapman, P. W. ; Heaps, J. D. ; Schuldt, S. B. ; ...

The overall objective of this program is to identify and develop high-throughput, supported-growth methods for producing low-cost, large-area polycrystalline silicon sheet on ceramic, carbon, or reusable substrates. The first method being investigated is the SCIM coating technique. (SCIM is an acronym for Silicon Coating by Inverted Meniscus.) With this technique, a low-cost ceramic substrate is silicon-coated in a continuous manner by passing the substrate over a molten silicon meniscus which is contained in a narrow fused-silica trough. During this reporting period, several mullite substrates were silicon-coated with this method. The best coatings were approximately 100 ..mu..m thick with large columnarmore »« less

Spray solar cell research: CdS/Cu/sub 2/S cells by ion exchange-CSD. Quarterly report No. 1, October 1-December 31, 1979

Technical Report Maruska, H. P. ; Young, II, A. R.

A study of the applicability of the Chemical Spray Deposition-Ion Exchange Technique to the formation of high efficiency, low cost Cu/sub 2/S/CdS solar cells has been undertaken. A Chemical Spray Deposition (CSD) apparatus and an Ion Exchange annealing station have been designed, and construction of these facilities is nearing completion. The object is to form films of CdO and Cu/sub 2/O by spraying appropriate solutions onto a heated substrate, and then to convert these oxides into CdS and Cu/sub 2/S through ion exchange by annealing in H/sub 2/S vapor. Such films will then be the basis for fabricating Cu/sub 2/S/CdSmore »« less

Technical Report

Samples of screen printed cadmium sulfide were supplied to the Institute of Energy Conversion of the University of Delaware for the application of copper sulfide via the evaporated cuprous chloride technique. Results of this activity are not available at this time. Problems were encountered in reproducing the previously obtained low resistivity cadmium sulfide films. The probable cause of this problem is in the atmosphere control for the furnace. The furnace has been extensively modified. When completed the modifications will permit greater control over the atmosphere, flow rate, and composition. A trial solar cell was prepared. While its short circuit currentmore »« less
Indium phosphide/cadmium sulfide thin-film solar cells. Quarterly technical progress report No. 1, June 1979-August 1979

Technical Report Zanio, K.

Cadmium sulfide and InP thin films were prepared by thermal evaporation and planar reactive deposition, respectively. Polycrystalline CdS films up to 10 ..mu..m thick showed absorption losses of less than 10% over the 0.6- to 1.0-..mu..m wavelength range. A threefold increase in lateral grain size was achieved when CdS/ITO/GLASS structures were partially recrystallized in flowing H/sub 2/S/Ar at 550/sup 0/C. InP deposited onto (100) InP semiinsulating substrate at substrate temperatures as low as 260/sup 0/C was n-type with room-temperature mobilities as high as 1500 cm/sup 2//Vsec. The CdS and InP films were integrated into an all-thin-film InP/CdS/ITO/GLASS structure.
