Abstract :
Hydrogenated amorphous silicon oxide (a-SiO:H) deposited by plasma-enhanced chemical vapor deposition(PECVD) using a mixture of silane (SiH4), hydrogen (H2), and nitrous oxide (N2O) at a low substrate temperature were used as passivation layers for heterojunction solar cells. The ratio of SiH4 to N2O and annealing time were optimized. The heterojunction solar cells manufactured under the optimum conditions exhibited the power conversion efficiency of >;17 %.
