NOVELTY - Fabrication of solar cell comprises forming a P-doped layer and N-doped layer in a silicon substrate (100), forming a dielectric top passivation layer and dielectric bottom passivation layer (140) on top surface of substrate, forming an antireflective coating (145) on top passivation layer, photolithographically forming two sets of openings, forming first and second metal silicide contacts, forming metal contact frames (170) and metal bus bars (175) on metal silicide contacts, and singulating the substrate into solar cell chips each including a contact frame and bus bar.    USE - Fabrication of solar cell.    ADVANTAGE - The method has migrated the costs of fabricating solar cells by using combinations of conventional semiconductor processes, integrating solar cell fabrication into conventional integrated circuit chip fabrication facilities and utilizing scrap integrated circuit chip wafers.    DETAILED DESCRIPTION - Fabrication of solar cell comprises:    (A) forming a P-doped layer and N-doped layer in a silicon substrate (100), where P-doped layer is adjacent to a top surface of substrate and N-doped layer is adjacent to a bottom surface of substrate;    (B) forming a dielectric top passivation layer on top surface of substrate and dielectric bottom passivation layer (140) on top surface of substrate;    (C) forming an antireflective coating (145) on top passivation layer;    (D) photolithographically forming a first set of openings through antireflective coating and through top passivation layer to P-doped layer, and photolithographically forming a second set of openings through bottom passivation layer to N-doped layer;    (E) forming first metal silicide contacts to P-doped layer and second metal silicide contacts to N-doped layer in first and second openings, respectively;    (F) forming metal contact frames (170) on first metal silicide contacts and metal bus bars (175) on second metal silicide contacts; and    (G) singulating the substrate into solar cell chips each including a contact frame and bus bar.
