Abstract

Intrinsic hydrogenated amorphous silicon oxide i-a-SiO:H films were used as front and rear buffer layers in crystalline silicon heterojunction c-Si-HJ solar cells. The surface passivity and effective lifetime of these i-a-SiO:H films on an n-type silicon wafer were improved by increasing the CO2-SiH4 ratios in the films. Using i-a-SiO:H as the front and rear buffer layers in c-Si-HJ solar cells was investigated. The front i-a-SiO:H buffer layer thickness and the CO2-SiH4 ratio influenced the open-circuit voltage , fill factor FF, and temperature coefficient TC of the c-Si-HJ solar cells. The highest total area efficiency obtained was 18.5%  mV,  mA-cm

, and . The TC normalized for this c-Si-HJ solar cell efficiency was −0.301%-°C.
