Description/Abstract Efforts to make ingot technology cost effective for the production of low cost solar cells in the 1980 to 1986 timeframe have been divided into both the development of a continuous CZ growth process and advanced ingot slicing.^The direction of this program is aimed towards the development and demonstration of enhanced I.D. slicing technology that will significantly increase the number of usable slices per inch of ingot over industry practice.^This method will require a reduction of both blade and slice thickness.^The required technologies to achieve these goals are: ingot rotation with minimum exposed blade area, dynamic cutting edge control, and the use of prefabricated insert blades.^Demonstration runs, incorporating ingot rotation with minimum exposed blade area in the slicing process, were performed.^These tests demonstrated clearly that control of the cutting edge position is required for blades with cores < 90 ..mu.. to assure minimum blade deflection as well as cutting stability at a reasonable cutting feed rate.^Blade development efforts to reduce kerf loss of 152 ..mu.. through introduction of a prefabricated insert are continuing.^An alternative blade construction requiring special etching techniques was developed which will produce a kerf of 152 ..mu...^The blades are presently manufactured and will undergo extensive testing shortly.
