Low cost - high efficiency MIS/inversion layer solar cells

Abstract

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 <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> .
