We have developed a-Si-based solar cells with plastic film substrate and ac
hieved a stabilized efficiency of 9% in a 40 cm x 80 cm cell. The structure
and fabrication process of flexible solar cells are presented. Then we dis
cuss the merits and demerits of our process from the viewpoint of mass prod
uction, and clarify that the SCAF cell has a good adaptability to mass prod
uction. (C) 2001 Elsevier Science B.V. All rights reserved.
