In 1996 a conversion efficiency of 17.1% had been obtained on 15 cm x 15 cm
me-Si solar cell. In this paper, large-scale production technology of the
high-efficiency processing will be discussed. Enlarging reactive ion etchin
g (RIE) equipment size, technology of passivation, and fine contact grid wi
th low resistance by screenprinted metallization, which is firing through P
ECVD SiN, have been investigated. (C) 2001 Published by Elsevier Science B.
