We report the properties of nanocrystalline silicon nip solar cells deposited onto two types of silver/zinc oxide backreflector with substantially different morphologies and reflectances. For both types, the short-circuit photocurrent density J SC un

We found that for O content as high as ∼2×10 19 at./cm 3 , hydrogenated nanocrystalline silicon (nc-Si:H) solar cell having 10.6% efficiency is attainable, when a small amount of B ∼1–3×10 16 at./cm 3 is incorporated. Micro-doping compensatio

We studied the effect of Ag/ZnO back reflectors (BRs) with textured Ag and thin ZnO layers on hydrogenated nanocrystalline silicon (nc-Si:H) solar cell performance. We found that the photocurrent density increases with Ag texture when the surface roo

We report on a direct measurement of electrical potential and field profiles across the n-i-p junction of hydrogenated nanocrystalline silicon (nc-Si:H) solar cells, using the nanometer-resolution potential imaging technique of scanning Kelvin probe

We report the results of using n-type hydrogenated nanocrystalline silicon oxide alloy (nc-SiOx:H) in hydrogenated nanocrystalline silicon (nc-Si:H) and amorphous silicon germanium alloy (a-SiGe:H) single-junction solar cells. We used VHF glow discha

Microscopic structure and solar cell performance in hydrogenated mixed-phase thin film silicon (Si:H) solar cells are studied. The samples were made with RF glow discharge with different hydrogen dilution profiles. The material properties were measur

We show experimentally that the photocurrent of thin-film hydrogenated microcrystalline silicon (?c-Si:H) solar cells can be enhanced by 4.5?mA/cm2 with a plasmonic back reflector (BR). The light trapping performance is improved using plasmonic BR wi

We optimized Ag/ZnO back reflectors (BR) for hydrogenated nanocrystalline silicon (nc-Si:H) solar cells by independently changing the textures of the Ag and ZnO layers. We found that Ag/ZnO with textured Ag and thin ZnO provides the highest nc-Si:H s

We report on our systematic study of light trapping effects using Ag/ZnO BRs for nc-Si:H solar cells. The texture of Ag and ZnO was optimized to achieve enhancement in photocurrent. The light trapping effect on photocurrent enhancement in solar cells

We present an approach to estimating the light-trapping of thin film silicon solar cells by comparing the measured quantum efficiency spectrum and the theoretical absorptance spectrum based on ideal diffractive light scattering. The ideal diffractive
