Abstract

In a recent article, Peters et al. [J. Appl. Phys. 105, 124509 (2009)] claim to have observed photosensitization of crystalline silicon by energy transfer from an optically absorbing thin polymer film. We show that this claim is not justified. Their experimental design is not adequate to establish enhanced photoexcitation of silicon; moreover, the theoretical arguments in their interpretation do not stand up to scrutiny.
