A 16.6% efficient Silicon-Film
TM solar cell has been
demonstrated and verified on a one-square-centimeter device. This result
was achieved with an improved blue response using an optimized
low-temperature PECVD oxide passivation and reduced optical losses by
the reduction of grid obscuration and front reflectance. Ongoing efforts
have been centered on the material growth to better

impurities and defects, post-growth material enhancements to effectively
remove impurities and passivate bulk defects, and device optimisations
to further reduce device optical and electrical losses. Model
calculations indicate that an efficiency over 18% is achievable if
further optimizations in antireflection coating and improvements in
minority carrier diffusion length can be effected
