Low cost - high efficiency MIS/inversion layer solar cells

This letter reports the highest total area efficiency (a probable 16% or greater for AM1 conditions) yet achieved for MIS Inversion Layer (I.L.) silicon solar cells. The cells have the MIS-IL structure with the inversion layer contacted by a MIS grid and induced on p-silicon by a spin-on tantalum oxide layer containing some SiO
