It is demonstrated that the deposition and postdeposition sintering of an antireflection (AR) coating in hydrogen acts to passivate silicon solar cells. Cells with and without an SiO/sub 2/ passivating layer, coated with a TiO/sub x//Al/sub 2/O/sub 3/ AR coating showed comparable enhancements in short-wavelength spectral response and in open-circuit voltage V/sub oc/ after sintering at 400 /sup 0/C for 5 min in a hydrogen ambient. The improvement in V/sub oc/ of cells without SiO/sub 2/ is attributed to front surface passivation by the AR coating during processing.
