High Performance Amorphous Silicon Oxide Thin Film Solar Cells Fabricated at Very Low Temperature

Present thin film solar cells with hydrogenated amorphous silicon oxide (a-SiO:H) as an absorber suffer from low fill factor(FF) of 61~64 [%] in spite of its benefits related to high open circuit voltage ( $V_{oc}$ ). Since degraded quality of a-SiO:H absorber by alloying with oxygen can affect th...
