摘要
The optical impacts of thin SiO2 passivation layer on industrial Si solar cells are modeled. The modeling shows that negligible optical loss results from SiO2 of <18 nm thickness in combination with an adjusted thickness of conventional SiNx anti-reflective coating. Thermally-grown SiO2 was applied as the front surface passivation of industrial Si solar cells with high sheet-resistivity (115 Omega/sq) emitter. Considerable improvement was observed in effective minority carrier lifetime, and 9 mV of Voc and 0.1% ( absolute) of cell efficiency gains have been attained with similar to 18 nm thick SiO2 grown at 850 degrees C over the industrial-type reference cells.
