Large area silicon sheet via EFG tube growth
Abstract
The EFG growth of small diameter silicon tubing has been reported. The work has now been extended to large polygons to produce inexpensive sheet material for solar cells. The advantages of tube growth remain essentially uncompromised. With a periphery of 48.8 cm and growth speeds of up to 3.0 cm/minute, formation rates of 146 sq cm/minute are achieved with nine-sided polygons. Substrates for solar cells are readily cut from the nonagons. The resulting material is similar to that of the smaller tubing. Solar cells with more than 13% efficiency are fabricated.
