Abstract
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 SiO2 passivating layer, coated with a TiOx/Al2O3 AR coating showed comparable enhancements in short-wavelength spectral response and in open-circuit voltage Voc after sintering at 400 °C for 5 min in a hydrogen ambient. The improvement in Voc of cells without SiO2 is attributed to front surface passivation by the AR coating during processing.Keywords
