Electrodeposition of polycrystalline and amorphous silicon for photovoltaic applications. Quarterly technical progress report No. 01, June 11, 1979-September 10, 1979
Abstract
The first quarter of the contract period was spent principally in designing, constructing, and testing the two cells for low and high temperature electrodeposition of silicon. The glass, low temperature cell for use with organic solvents incorporates the advantageous features of a small cell volume requiring less than 50 ml of solvent, use of Ace threaded adapters for easy dismantling and cleaning, and an in-line geometry of the working electrodes and a window permitting illumination of the cathode during or after the electrodeposition. Several survey experiments were made with the glass cell using SiHCl/sub 3/ and SiCl(CH/sub 3/)/sub 3/ as the silicon precursors. Use of the former with AgCl/Ag as the reference electrode resulted in decomposition of the reference resulting in plating of silver on the electrode. It was also determined that LiAsF/sub 6/ is not usable as the supporting electrolyte with SiHCl/sub 3/. The cyclic voltammogram of the SiCl(CH/sub 3/)/sub 3/ solution showed two reduction peaks, but no indication of silicon deposition was observed. The high temperature cell for electrodeposition from molten salts was made from a nickel tube fitted with a lid using vacuum components to allow inlets for the electrodes, a pumping port, helium bubbler, and thermocouple.more »
